List(V1.3, 2.x, 3.x in C:)
NAME
List - List contents of a directory.
SYNOPSIS
List listname Dir P=PAT/k KEYS/s DATES/s NODATES/s SUB/k
SINCE/k SORT/s TO/k UPTO/k QUICK/s BLOCK=BLOCKS/s
NOHEAD/s FILES/s DIRS/s LFORMAT/k
DESCRIPTION
List displays the contents of a given directory. By
contents, we mean the names of the subordinate files and
directories, not the file data. Typing the List command
by itself with no parameters generates a listing of the
current directory. It also lists any comments attached by
a FILENOTE command.
THE LISTING DISPLAY
List displays your files and directories one per
line, with all the protection flags currently turned on
right next to the filename. The fields which may appear
in a Listed file are
name [KEY] size/type protection date time
:comment
Methods are provided for getting a selective listing
of files, as well as suppressing/adding most of the above
display elements.
A description of each one of the above elements is
given below:
Name
The name of the file or directory. This can be a
device or volume name. AmigaDOS wildcards are supported
100%. The inclusion of wildcards eliminates the need for
the P (or PAT) keyword. PAT is retained to keep
compatiblility with older versions of AmigaDOS.
KEY
This is the actual block number of the file or
directory block header. This is not displayed by
default, you must use the KEYS switch to generate this
element of the listing.
size/type
This element gives the size of the file in bytes, or
the string "empty" if the file is empty. If this is a
directory and not a file, then the directory indicator
("Dir") will appear here.
protection
The protection bits of the current file, in the order
hsparwed. If any of these is disabled, a dash (-) will
appear in its place. The protection bits stand for
"hidden, script, pure, archived, read, write, execute and
delete", respectively.
date time
The date and time of the last modification to the
file or directory. The format of the date display is
determined by the value of the environment variable
dateformat. These elements of the listing appear by
default, but may be selectively added or subtracted by
using the DATES or NODATES keywords.
comment
The comment as set by Filenote. If no comment
exists, this field will not be displayed. Note that it
is displayed on a line by itself, preceded by a colon.
SELECTIVE LISTING OF FILES
The methods described in this section allow you to
list a portion of the files and directories on your
disks. Ways exist to generate a list of files that
conform to a certain pattern, or that were
created/modified before or after a certain date. You may
also combine these options, for example, you may get a
list of all files which end in .c and were created or
modified since a certain date. These options are
described below:
Dir
List this directory instead of the current directory.
This parameter may be a filename, in which case the
single file is shown. You may also use any legal
AmigaDos pattern in this position, in which case the
files and directories listed will be those which match
the pattern, if any. (This feature was added to the BCPL
List in the V1.3 enhancer.)
PAT
List only files and directories which match the
pattern. You must specify the keyword PAT or its
abbreviation P. This is no longer truly necessary with
the expanded capabilities of AmigaDOS wildcards, since it
is usually more convenient to simply include the pattern
in the directory specification as described above. It is
included for BCPL compatibility.
SUB
In this option the SUB keyword must come before the
string. If spaces are in the string, it must be enclosed
in quotes. With the inclusion of AmigaDOS wildcards, this
keyword is really not needed. It searches for an
occurence of the substring anywhere within the directory
name or filename. Think of this as a short form of "List
PAT *substring*" or a long form of "List *substring*".
List will reject any attempts to combine the use of PAT
and S. Wildcards in the initial DIR argument are matched
and then checked again to match against the substring.
SINCE
While the pattern matching options above filter files
and directories on the basis of their names, this option,
and the following UPTO option, filter out files based on
their last modification date. SINCE displays only files
which have been created or modified on or later than the
specified date. All older files are not displayed. You
may specify the date in the currently defined dateformat
(see Environment Variables) or you may use a word such as
SUNDAY, TODAY, YESTERDAY, etc.
UPTO
The inverse of SINCE, this option displays only files
and directories which have been modified or created on or
before the specified date. Files younger than this date
are not displayed. See SINCE for a description of the
date format list expects.
FILES
Display only files, and not the directories.
DIRS
Display only directories, and not the files.
CONTROLLING THE DISPLAY
The options below allow you to alter the format of
the display listing, or to send it to another file or
output display device (that's usually a printer).
TO
You can specify a file or a device you wish the
listing to be sent to using this keyword. If not
specified, the default of the current screen will be
used. If the file already exists then the old file will
be replaced (and gone forever) while being replaced with
this new file. If the protection bit is set on the old
file LIST will not work. It is very useful to LIST TO
prt: to get a hard copy of your disk listing.
DATES
Forces the date and time of creation to be displayed
in the current dateformat. This keyword does not have to
be used unless you are using the QUICK or NODATES
keywords.
NODATES
Will not display time and date information, only the
filename, size, protection and comment fields will be
displayed. Using DATES with this will force the creation
dates and times to display.
QUICK
Displays only the filename field, one filename per
line, with no trailing spaces. You can LIST just the
files or direcotries by using the FILES or DIR options.
You can combine this with other options such as DATES and
KEYS to selectively enable these fields. Under 2.x/3.x
KEYS no longer works with this keyword.
KEYS
Displays the block number of each file header or
directory header. All files are assigned using block
numbers. This is how AmigaDOS keeps track of your files.
Each file has a unique block number assigned to it. This
is its address on the disk. The block number appears to
the left of the file length.
SORT
Sorts the file and directory names into ascending
alphabetical order. Case is disregarded. Note that this
is an option available only with the ARP list. Sorts by
DATE if you include the DATES keyword.
BLOCK=BLOCKS
Displays filesizes in blocks, rather than bytes.
NOHEAD
Suppresses the default "Directory..." header and the
"x files -x directories -x blocks used" footer display.
LFORMAT
LFORMAT can be used to control the output of list,
and especially to generate command lines to be fed to the
shell. LFORMAT can is most useful when you want to
generate a script file. To send the LIST output to a
script file, you can either redirect LIST's output using
the ">" or "TO" keywords. LFORMAT takes a string as an
argument which can be any ascii string.
The LFORMAT substring can be used multiple times.
This allows you to use the listing name more than once
per line. The second time you use the string the first
relative path will be replaced by %S, and the path of the
second argument will be used (BTW, a relative path is
merely the list of directories you must traverse to get
from the specified directory to the current one.) If you
use three substrings, then the first will be replaced by
the relative path, while the second and third will be the
file or subdirectory names. If you use it four times, the
first and third will be the relative paths, and the
second and fourth will be the subdirectory or file names.
To include the output of List in this string, you can
use the "%S" sequence under 1.3 or 2.x/3.x as follows:
"%S" Filename
"%S%S" Pathname/Filename
"%S%S%S" Pathname/FilenamePathname
"%S%S%S%S" Pathname/FilenamePathname/Filename
The following information may be substituted for the
string as output and is for 2.x/3.x Only:
%A :Attributes (protection flags)
%B :Size of file in blocks
%C :Comments attached to the file
%D :Date of file creation or last update
%F :The complete absolute path (starting with the
volume name)
%K :Key block number
%L :Length of the file in bytes
%N :Name of the file
%P :The relative path(starting at the current directory)
%T :Time of creation or last update
The following information may be substituted for the
string as output and is for 2.1/3.x Only:
%E :Extension only (the part of the filename after the
last period)
%M :Filename minus the extension (everything up to
the last period)
ALL :Lists the contents of all the subdirectories of the
specified directory, as well as the directory itself.
The %S's may be separated by spaces, other ascii text
or nothing, as above. Here is an example of LFORMAT that
will create a script to Type each file:
List LFORMAT="Type %S%S"
Of course, to use this, you must save it in a file
using TO or one of the IO Redirection operators ('>',
'>>'). If you are using 2.x/3.x, you can also pipe the
output of List directly into the Execute command.
ENVIRONMENT VARIABLES
The List uses the same dateformat variable as used by
the Date command, and in essentially the same way. If it
is not defined, or if it has an illegal value, the
default AmigaDOS display and input is used. Otherwise,
the display and the input of dates is determined as
follows:
0 AmigaDOS format DD-MMM-YY.
1 International format YY-MM-DD.
2 U.S. format MM-DD-YY.
3 Canada DD-MM-YY
If you prefix the above numbers with a dash, then the
display of names like TODAY, MONDAY, FUTURE, etc., will
be disabled and the format string as defined above will
be used exclusively. Note that this governs the format
that List expects as input as well as the format List
uses for display.
EXAMPLES
1. To display all files in df1: ending with the
characters "#?.c" which were modified later than TUESDAY
at 00:00 hours.
List df1:#?.c SINCE WEDNESDAY
2. To output just the names and dates for items in
the current directory beginning with the letters 'stuff'
that were created or last updated on or before April 16,
1967. Sent the output out to a file called 'StuffOut' in
the Ram:T directory.
LIST stuff#? QUICK DATES UPTO 16-Nov-67 TO Ram:T/StuffOut
3. To list the information about the contents of the
current CLI directory.
LIST
4. To print the block number of all the files in the
current directory.
LIST KEYS to PRT:
or
LIST > PRT: KEYS
5. To display the information about the files in the
directory art/adult whose names contain the string
'girls'
LIST art/adult/#?girls#?
(note: Information about both 'Really Ugly Girls' and
PrettyGirls would be displayed)
6. To set the pure bit of every file in the stuff:
directory.
LIST >RAM:ThisFile stuff:#? LFORMAT "protect %S +p"
(now you have a file called Ram:ThisFile which contains
the commands to set the PROTECT bit on all the files in the
stuff: directory. Now, just EXECUTE RAM:ThisFile
