\ADDBUF ADDBUFFERS
Reduces disk access time by adding cache buffers
Format:  ADDBUFFERS df<x>: <nn>
Adds <nn> buffers to drive df<x>:
Example: ADDBUFFERS df0: 20
This would add 20 buffers to drive df0:.
Notes: Adding buffers to a drive can improve disk access times significantly,
although if you add more than about 30 buffers to any one drive the improve-
ment will be much less noticeable.~
\ASSIGN ASSIGN
Assigns a logical device name to a directory
Format:  ASSIGN [[<name>]<dir>][LIST]
Assigns logical device name <name> to directory <dir>.
Example: ASSIGN C: RAM:C
This assigns logical device C: to directory RAM:C. In otherwords it tells
AmigaDos to look at RAM:C whenever a reference to C: is encountered.
Notes: If ASSIGN is suplied without a parameter or with the LIST switch set
then a list of all the current assignments will be displayed.~
\BINDDR BINDDRIVERS
Binds device drivers to add-on hardware
Format:  BINDDRIVERS
Example: BINDDRIVERS
This would bind any device drivers found in the SYS:Expansion drawer to the
relevant add-on hardware. If there is an icon in the SYS:Expansion drawer
for a piece of add-on hardware then that hardware will be configured auto-
matically when the BINDDRIVERS command is called. It is usually called as
part of the startup-sequence.~
\BREAK  BREAK
Sets attention flags in a process
Format:  BREAK <task>[ALL][C][D][E][F]
Sets the attention flags of task <task>. C would set the CTRL-C flag, D
would set the CTRL-D flag and so on. If ALL is specified then all the
CTRL flags for the given task will be set.
Example: BREAK 2 C
This would set the CTRL-C flag of task 2 (thereby stopping the task).~
\CD     CD
Sets or changes the current directory
Format:  CD [<dir>]
Changes the current directory to directory <dir>. If CD is supplied without
any parameters then the name of the current directory will be displayed.
Example: CD C
Would change the current directory to C/.
Notes: The <dir> parameter can also be supplied as a /. This would change
the current directory to the directory that owns the current one, if any.~
\CHANGE CHANGETASKPRI
Changes the priority of a task
Format:  CHANGETASKPRI <priority>
Changes the priority of the current CLI task to <priority>. The priority
can be in the range -128 to +127 although you should only use -5 to +5 to
avoid upsetting important system tasks.
Example: CHANGETASKPRI 5
Would change the priority of the current CLI task to 5. This would give the
current task and any other task started from it priority of any other CLI
tasks.
Notes: Normally, most user CLI tasks have a priority of 0.~
\COPY  COPY
Copies a file or directory from on place to another.
Format:  COPY [[FROM]<name1>][TO<name2>][ALL][QUIET]
Places a copy of the file or directory <name1> in the file or directory
<name2>. If ALL is specified, any subdirectories will be copied and created
in the TO directory <name2>. The names of the files currently being copied
will be displayed unless the QUIET switch is set.
Example: COPY file1 to D:file2
Copies file1 from the current directory to file2 in directory D:
         COPY TO df1:
Copies all the file from the current directory to drive df1:
         COPY DF0: TO DF1: ALL
Copies all the files from drive DF0: to drive DF1:
         COPY DF0: TO DF1: ALL QUIET
Does the same as the previous example but doesn't tell you the file that is
currently being copied.
         COPY file1|file2|file3 TO df1:
Copies file1, file2 and file3 to drive df1:~
\DATE   DATE
Sets or displays the system date or time
Format: DATE [<date>][<time>][TO|VER<name>]
Date <date> sets the date which should be supplied in the format DD-MMM-YY.
You can also set the date forward to a particular day by specifying the day
or by specifying 'tommorow' or 'yesterday'.
Date <time> sets the time which should be supplied in the format HH:MM.
You can specify both the date and the time together by placing a space
between the two. You can specify where the output from DATE is sent by using
the keywords TO or VER which both mean the same.
Example: DATE
Displays the current date and time
         DATE 28-SEP-88
Sets the date to the 28th September 1988
         DATE 11:34
Sets the time to 34 minutes past 11.
         DATE 28-SEP-88 11:34

         DATE TO DATERECORD
Send the current date to file DATERECORD~
\DELETE DELETE
Deletes a file or directory
Format:  DELETE <name>[<name*>][ALL][Q|QUIET]
Deletes each file that you specify. If you specify more than on file the
filenames should be seperated by a space. You can delete up to ten files
in this way. If you specify a directory to be deleted, that directory
must contain no files.
You can also specify ALL when deleting a directory. The directory and all
it's files and subdirectories and all their files will be deleted.
As each file is deleted a message will be displayed telling you such unless
you specify the QUIET flag.
Example:  DELETE file1
Deletes file1 from the current directory
          DELETE mydirectory ALL QUIET
Deletes all the files and all the subdirectories and their files from
directory mydirectory without displaying the files it deletes.
          DELETE file1 file2
Deletes file1 and file2 from the current directory~
\DIR    DIR
Displays the files in a directory
Format:  DIR [<name>][OPT A|I|AI]
Displays a list of all the files and subdirectories in directory <name>. DIR
without any parameters will display the files and subdirectories in the curr-
ent directory. If OPT A is specified, all the files and subdirectories of any
subdirectories in the current directory will be displayed. If OPT I is speci-
fied, DIR will go into interactive mode. The files and directories will be
displayed with a question mark to the right of each name. You can then do one
of the following:
 Press RETURN to go onto the next file in the directory
 Enter Q to quit displaying the directory
 Enter B to go back to the last name in the list
 Enter E to enter the directory and display the files and subdirectories of
 that directory
 Enter DEL to delete that particular file or directory
 Enter T to 'type' that file to the screen (display it).
Example:  DIR
Displays all the files and subdirectories in the current directory.
      DIR C
Displays all the files and subdirectories in directory C/.
      DIR df0: OPT A
Displays all the files and subdirectories and all the files in those subdir-
ectories of drive df0:. In otherwords it shows everything on the disk.~
\DISKCH DISKCHANGE
Tells AmigaDos that you have changed the disk in a 5╝" drive
Format:  DISKCHANGE <drive>
Tells AmigaDos that you have inserted a different disk in dive <drive>
Example: DISKCHANGE df2:
Tells AmigaDos that you have changed the disk in drive df2:~
\DISKCO DISKCOPY
Copies the contents of one 3╜" disk to another
Format:  DISKCOPY [FROM]<disk1>TO<disk2>[NAME<name>]
Makes a copy of <disk1> on <disk2>, formatting disk2 as it does so. You can
also set the name of <disk2> by specifying <name>.
Example: DISKCOPY DF0: TO DF1:
Copies the entire contents of the disk in drive df0: to the disk in drive
df1:
Notes: Normally this command is used to make a backup of a disk.
During the copy DISKCOPY will prompt you to change disks if neccessary by
displaying a requester. You should change the disks then click on continue.~
\DISKDO DISKDOCTOR
Repairs a corrupted disk
Format:  DISKDOCTOR <drive>
Repairs the disk in drive <drive>. If AmigaDos reports that a disk could
not be validated, then that disk is corrupt. DISKDOCTOR will restore as much
of the disk's file structure as possible.
Example: DISKDOCTOR DF1:
Tells DISKDOCTOR to try and restore the files on the disk in drive Df1:.
Notes: Once you have used DISKDOCTOR on a disk you should copy
all the files from that disk that you want to keep onto another disk and
re-format the corrupted disk.~
\ECHO   ECHO
Displays a message
Format:  ECHO <string>
Writes the string <string> to the current output stream (usually the console)
Example: ECHO "Hello!"
Displays the message "Hello!".~
\ED     ED
Calls the screen editor
Format:  ED [FROM]<filename>[SIZE<bytes>]
Calls the screen editor to edit the file <filename>. ED will allocate a
number of bytes in memory for the file to be copied into. The default number
of bytes that ED allocates is 40000 but this can be changed by specifying the
SIZE parameter. If <filename> does not exist, ED will create it.
Example: ED myfile
Edits the file myfile. If myfile didn't already exist then it will be created
         ED myfile 60000
Edits the file myfile allocating 60000 bytes of workspace~
\EDIT   EDIT
Calls the line editor
Format:  EDIT [FROM]<file1>[[TO]<file2>][WITH<file3>][VER<file4>]
           [OPT<option>]
Edits file <file1>, writing the edited file to <file2>, if specified. If the
TO file is not specified, a temporary file is created and the edited file is
copied into it. Then, if the edit commands Q or W are used, the temporary
file is renamed to the name of the FROM file. Before this renaming takes
place, the unedited original file is copied into a file in directory t/
called edit-backup. If the edit command STOP is used no changes will be made
to the original FROM file.
Edit commands are usually taken from the keyboard but they can also be
taken from a file. You specify this file as the WITH parameter.
Messages from EDIT can be sent to a file instead of the screen by specifying
a VER file.
You can specify options with OPT. Option Pn sets the maximum number of prev-
ious lines to n. Option Wn sets the maximum line width to n characters.
Example: EDIT myfile
Edits the file myfile then when editing is finished copies the old unedited
file into t/edit-backup.
           EDIT myfile TO thatfile
Edits the file 'myfile' and writes the edited file to 'thatfile'.
           EDIT myfile TO thatfile WITH edits VER messages
Edits the file 'myfile' to 'thatfile' using the editing commands in the file
'edits'. Any messages from EDIT will be sent to file 'messages'~

Format:  ENDCLI
Example: ENDCLI
Ends the current interactive CLI process.~
\EXECUT EXECUTE
Executes a file containing CLI commands
Format:  EXECUTE <commandfile>[<args>*]
Executes the file called <commandfile> and passes the arguments <args> to
the file.
Example: EXECUTE mycommands df0:
Executes the file 'mycommands' passing the argument 'df0:' to the file.~
\FAILAT FAILAT
Tells a command sequence to fail if a specified error occurs
Format:  FAILAT <errno>
Instructs a command sequence to fail if an error that has an error code of
<errno> or greater occurs.
Example: FAILAT 30
Instructs a command sequence to fail if an error code of 30 or greater is
generated.~
\FAULT  FAULT
Displays error messages corresponding to the specified fault codes
Format:  FAULT [<faultno>*]
Displays the error message associated with fault code <faultno>.
Example: FAULT 225
This would display the error message associated with fault code 225. In this
example, this would be 'not a DOS disk'.
        FAULT 225 226 227 228
Would display the error messages associated with fault codes 225, 226, 227
and 228.~
\FILENO FILENOTE
Attaches a note or comment to a file
Format:  FILENOTE [FILE]<file>COMMENT<comment>
Attaches comment <comment> to the file <file>
Example: FILENOTE myfile COMMENT "This file took days to enter"
Attches the comment 'This file took days to enter' to file 'myfile'. This
has the effect that if you do a LIST of the file the comment will appear
on the line below the filename.~
\FORMAT FORMAT
To format a disk in the format required by AmigaDos
Format:  FORMAT DRIVE <drivename> NAME <volumename>
Formats a disk in drive <drivename> and initialises it and calls it
<volumename>. The name to be given to the disk can be up to 30 characters
long. If the name contains a space, you should enclose it in quotes.
WARNING - FORMAT WILL COMPLETELY CLEAR THE DISK. IF THE DISK IS NOT
          EMPTY YOU WILL LOOSE THE CONTENTS.
Example: FORMAT DRIVE df0: NAME mydisk
Will format and initialise the disk in drive df0: and assign the name
'mydisk' to it.~
\IF     IF
To allow conditionals within a command sequence
Format:  IF [NOT][WARN][ERROR][FAIL][<string>EQ<string>][EXISTS
         <filename>]

Notes: The MOUNT command is normally issued as part of the
startup-sequence.~
\NEWCLI NEWCLI
Creates a new interactive CLI process with a window
Format:  NEWCLI [<window>][FROM <filename>]
Creates a new CLI window. You can specify the size, position and title of
the new window using the <window> parameter. This take the form:

where x and y are the coordinates of the window's upper left hand corner,
width and height are width and height of the window in pixels and title
is the title of window, displayed in the windows title bar. If the title
contains a space the entire <window> parameter should be enclosed in
double quotes.
You can also specify a FROM parameter which tells the new CLI to execute

\PATH   PATH
Adds or changes the directories that AmigaDos searches for commands to
execute
Format:  PATH [SHOW]|[ADD <dir>[,<dir>]...]|RESET <dir>[,
         <dir>]...]
By default AmigaDos looks in the current directory then SYS:C for a command
to execute. PATH ADD <dir> tells AmigaDos to look in directory <dir> for
commands to execute. PATH SHOW or PATH displays the directories in which
AmigaDos will look for commands. PATH RESET <dir> will replace the existing
search path with <dir>. Up to 10 directories can be specified with the PATH
command.
Example: PATH SHOW
Displays the directories in which AmigaDos will look for commands.
          PATH newcommands
Tells AmigaDos to look in directory 'newcommands' in addition to any other
directories that is looking in to find commands.

The options are as follows:
 r    means that the file may be read
 w    means that the file may be written to
 d      means that the file may be deleted
 e    means that the file may be executed
To set a file's protection status follow the filename with one or more of
the options. If you omit a particular option PROTECT assumes that you don't
require that option. So, if you gave all the options except d, the file
would be protected from deletion.
Example: PROTECT myfile re
Sets the protection status of file 'myfile' so it can only be read and
executed. It cannot be deleted or written to.
         PROTECT myfile rwed
Sets the protection status of file 'myfile' so it can be read, written to,
executed or deleted~
\QUIT   QUIT
Exits from a command sequence
Format:  QUIT [<returncode>]

Example: RENAME ThisFile TO Thatfile
Renames the file 'ThisFile' to 'ThatFile'~
\RUN    RUN
Executes commands as background processes
Format:  RUN <command>
Executes the command <command> as a noninteractive CLI process. A new non-
interactive CLI process will be started and <command> will be passed to it
as input. This new process will be run as a background task. If you want to
RUN several commands from a single RUN command type the command followed by
a plus (+) sign and press RETURN. Then type in the next command. When you
have finished typing in each command just press RETURN after the last one.
Example: RUN COPY myfile to PRT:
Sets up a noninteractive CLI process to copy the file 'myfile' to the
printer. Copying will take place as a background task, allowing you to
continue with what you are doing.
         RUN DISKCOPY DF0: TO DF1:+
     ECHO "Copy finished"
Sets up a CLI process to copy the entire contents of the disk in drive DF0:
to the disk in drive DF1: then displays the message 'Copy finished' when
DISKCOPY has completed.~
\SEARCH SEARCH

Format:  SEARCH [FROM]<dir>|<pattern>[SEARCH]<string>[ALL]
Saerch will look through all the files in directory <dir>  and, if you
specify ALL, all the subdirectories in that directory for the text string
<string>. It will display the name of the file that it is currently
searching and also the line in the file containing the text string that
you specified. You can also specify a pattern which will cause search to
only look for text matching this pattern.
Example: SEARCH mydirectory "Plastic chicken" ALL
Searches through the directory 'mydirectory' and it's subdirectories for
the text string 'Plastic chicken'.~
\SETDAT SETDATE
Changes the timestamp of a file or directory
Format:  SETDATE <filename> <date> [<time>]

\SETMAP SETMAP
Changes the key map of the keyboard
Format:  SETMAP <mapfilename>
Sets the key map of the keyboard to <mapfilename>. The <mapfilename>
parameter should contain the name of a file in directory :devs/keymaps
that holds the relevant key map information.
Example:  SETMAP usa
Sets the key map to usa, which is the standard key map on the Amiga. If
your Amiga has a British keyboard layout you would set the keymap to gb.~
\SKIP   SKIP
Peforms a jump in a command sequence
Format:  SKIP <label>
Jumps to the line a command sequence labelled as <label>. The label will
have been defined using the LAB command. If <label> is not specified, SKIP
will jump to next label in the command sequence.
Example: SKIP EndOfProg
Jumps to the line in a command sequence containing LAB EndOfProg~
\SORT   SORT
Sorts a file
Format:  SORT [FROM]<file1>[[TO]<file2>][COLSTART <n>]
Sorts the file <file1> into alphabetic order and puts the sorted file into
file <file2>. If the TO file isn't specified then <file1> will contain the
sorted text.
You can also specify the COLSTART parameter where <n> is the column number
that SORT will take as the starting point on each line to sort from.
Example: SORT file1 TO file2 COLSTART 5
Will sort file1 into alphabetical order into file2. Only text after the
5th character on each line will be sorted.~
\STACK  STACK
Sets or displays the stack size for commands
Format:  STACK [<n>]
Sets the stack size to <n> bytes. If the <n> parameter is ommitted STACK
will display the current stack size. The initial size of the stack is
4000 bytes.
Example: STACK 20000
Sets the stack size to 20000 bytes.
Notes: Some programs and commands may require a stack size
greater than the usual 4000 bytes. If you are unsure how large the stack
needs to be, it is best to overestimate the stack size. If there is not
enough space on the stack THE AMIGA WILL CRASH!~
\STATUS STATUS
Displays information about current CLI processes
Format:  STATUS [<process>][FULL][TCB][SEGS][CLI|ALL]
STATUS displays information about one or all existing CLI processes. It can
have a number of parameters. If the process number is specified as <process>
then the information displayed will be relevant to that process. The other
parameters are as follows:
SEGS    Displays the names of the sections on the segment list of each
    process
TCB    Displays information about the priority, stacksize and global vector
    size of each process
CLI    Displays CLI processes and the currently loaded command, if any.

FULL    Displays all of the information above

If STATUS is supplied without any parameters then the process number and
the program running in each CLI process will be displayed.
Example: STATUS 1 FULL
Displays full information about CLI process 1~
\TYPE   TYPE
Displays a text file as plain text or hexadecimal
Format:  TYPE [FROM]<file1>[[TO]<file2>][OPT N|H]
Copies the file <file1> to the screen or to <file2> if specified. If option
N is specified line numbers will be added to the output. If option H is
specified the file will be shown in hexadecimal format.

         TYPE myfile OPT H
Displays the file 'myfile' in hexadecimal form~
\WAIT   WAIT
Waits a specified time
Format:  WAIT <n>[SEC|SECS][MIN|MINS][UNTIL<time>]

specified WAIT will wait until the specified time. If wait is specified
with out any parameters the wait will be 1 second.
Example: WAIT 10 MINS
Waits 10 minutes
         WAIT UNTIL 10:00
Waits until ten o'clock in the morning~
\WHY    WHY
Explains why the previous command failed
Format:  WHY
Will display a fuller exaplanation of why the previous command failed
Example: Lets say that you had entered the command
            TYPE DF0:
AmigaDos displays the error message 'can't open DF0:'. You then type
            WHY
and the better explanation 'Last command failed because object not of
required type' is displayed.~

\HELP
                                   HELP ON HELP!

HELP! uses the following notations to explain the layout of a command:

< >        This indicates that you should fill in this parameter
                For example, CD <name>

[ ]        Square brackets indicate that the parameter or parameters
                are optional. For example, DIR [<name>]

|               A vertical bar seperates a number of alternatives you can
                use for the parameter. For example, DIR [OPT A|I]

<name>*        Means that more than one of the same kind of parameter can
                be supplied, seperated by at least one space. For example,
                DELETE <name>[<name>*]

    Remember, the more characters you supply in the keyword, the more
    chance you have of getting the help you need.
