File INFo V1.131 by Peter Struijk
Introduction
------------
FInf is a very versatile directory listing utility. It can examine the
contents of files and display a short type description. In addition to
this, FInf has a whole slew of options that allow you to filter files by
type, date, age, size etc., as well as recursive directory descending,
and adjustable output formatting. So next to simply listing
directories, FInf is extremely useful for creating hybrid commands that
perform functions closely tuned to your specific needs.
Command Line Arguments
----------------------
Usage: FInf [file/dir] [-lf=LFORMAT ["..%s.."]] [-nl=NOLINE [prefix]]
[EXE] [IMP] [DOC] [IFF] [NOI] [-t=TYPE string] [-nt=NOTYPE]
[-na=NOANSI] [-nh=NOHEAD] [NEWER [object]] [OLDER [object]]
[-d=DIRS] [-f=FILES] [-q=QUICK] [-p=PATH] [-a=ALL] [NOX] [NOC]
[BLOCK(S)] [DATES] [-lt=LONGTYPE] [SUB string] [BATCH]
[LARGER size] [SMALLER size] [SINCE [n] date] [UPTO [n] date]
[-ho=HEADONLY]
Arguments surrounded by double-quotes are NOT recognized as keywords,
this, or the use of -?? shortcuts can help you circumvent problems with
identically named files and keywords. Keywords/switches are case
independent.
FInf parses its arguments in a left to right order, which may cause
keywords to be overridden by keywords that occur later in the command
line. E.g. "FInf -nt doc" displays only text files while "FInf doc
-nt" will disable file type checking.
You may use the backslash "\" as a fixed escape character; If you enter
\n it will be replaced by a new-line, while \" implements a
double-quote.
FInf sets a returncode level of 20 (FAIL) on a serious error. If no
errors occur, yet no matching file can be found, a returncode 5 (WARN)
will be set.
Examples
--------
In order to whet your appetite, I'll start with a few examples. A
complete option reference is given later on.
Typing "FInf" without any options will display the files in the current
directory, e.g.
EM 14228 --p-rwed 12-Jul-90 22:47:39 XLIB IMP
TeX 130344 ----rwed 04-Feb-90 19:29:42 EXECUTABLE
Introduction 1918 ----rwed 21-Jul-90 15:23:12 ASCII TEXT
Read Me 1532 ----rwed 22-Jul-90 16:31:52 ASCII TEXT
Graph 4526 ----rwed 01-Jun-90 18:13:47 IFF PIC
Tmp (dir)
5 files - 1 directory - 307 blocks - 152548 bytes
Typing "FInf doc" will display all text files in the current directory,
and "FInf disk* exe" will show all executables starting with "disk".
If you use a shell that supports unnamed pipes and aliases, you can very
easily construct new commands as shown below. If you do not have
unnamed pipes, you can use the BATCH option, the PIPE: device or
temporary files to obtain equivalent though less elegant functionality.
The BATCH option will cause FInf to output to a temporary file and execute
the contents like a batchfile once it's done. This will give you the
same functionality as single level unnamed pipes.
------
E=FInf [] noi doc path files lformat " \"%s\"" noline ED | execute
or
E=FInf [] noi doc path files lformat " \"%s\"" noline ED batch
This alias will execute the command ED with a list of text files that
match any wildcards you specify. Typing "E" while in the directory shown
above would have executed the command `Ed "Introduction" "Read Me"'.
Note how escaping the quote character allows you to put quotes around
the produced filename, thus avoiding problems with filenames that have
spaces in them.
Do not be deterred by the numerous parameters. Aliases need to be
constructed only once, and when you are examining the requirements of
a new alias, you'll almost automatically conclude you're in need of
certain options. Chances are FInf provides them.
------
find=FInf NOTYPE FILES QUICK NOHEAD NOANSI PATH ALL SUB []
or abbreviated:
find=FInf -nt -f -q -nh -na -p -a SUB []
This alias will search your current directory, and all subdirectories
for filenames that contain a string you specify. You can search any
directory by specifying a directory name *after* the search string.
Very useful for finding files on your harddrive. If a matching file is
found, the full path will be displayed.
------
FInf *.c Quick Path All | Zoo aI <archive>
The I option in Zoo causes it to read filenames from the standard input,
and these are provided by FInf. This particular example will archive
all C source files in the current directory and its subdirectories.
File Type Filtering Options
---------------------------
FInf has a set of command line switches that causes it to display
only specific file types. Here's a list:
-t=TYPE <string>
When FInf recognizes a file, it is able to print a string describing its
type. The TYPE option allows you to display only those files where the
pattern <string> occurs in this file typeádescription. This keyword can
be used to select virtuallly any file type or groups of file types just
by supplying a carefully chosen <string>. Note that the LONGTYPE option
causes FInf to search the extended file type description instead of
searching the short description.
List of currently recognized file types:
The following list can be generated by "FInf ?" followed by another "?"
at the ":" prompt. FInf's file type recognition is not by any means
complete and even a bit outdated but serves well to distinguish between
major groups of files like e.g. executables, text, iff.
SHORT LONG
UNREADABLE "Unable to read"
UNKNOWN "Unknown type"
FIMP DATA "FImp data file"
OBJ CODE "Linkable object code"
TTW PIC "TTW picture"
PW DATA "PowerWindows data"
DIMP DATA "DImp data file"
IFF PIC "IFF picture"
IFF SOUND "IFF sound"
IFF SCORE "IFF score"
IFF TEXT "IFF text"
IFF DMS "IFF Deluxe Music score"
IFF ANI "IFF animation"
IFF S3D "IFF Sculpt 3D scene"
IFF DLV "IFF Deluxe Video"
IFF DOC "IFF document"
IFF FILE "IFF data file"
ASCII TEXT "ASCII Text"
OLD IMP "Old imploded"
NORM IMP "Normal imploded"
PURE IMP "Pure imploded"
OVLY IMP "Overlayed imploded"
XLIB IMP "Library imploded"
XLIB IMP! "Short library imploded"
EXECUTABLE "Executable"
OVERLAYED "Overlayed executable"
NORM IMP* "Protected normal imploded"
PURE IMP* "Protected pure imploded"
OVLY IMP* "Protected overlayed imploded"
XLIB IMP* "Protected library imploded"
FONT HDR "Font header"
WB ICON "WB icon"
DISK ICON "WB disk icon"
DRAWER "WB drawer icon"
TOOL "WB tool icon"
PROJECT "WB project icon"
GARBAGE "WB garbage icon"
DEVS ICON "WB device icon"
KICK ICON "WB kick icon"
In addition to filtering file types with the TYPE option there are a
number of often used types that may be directly specified by keyword.
These are:
EXE - Display executable files (except imploded executables).
IMP - Display imploded files and imploded data files.
DOC - Display ASCII text files.
IFF - Display all kinds of IFF files. You may also use the TYPE keyword
to accomplish further differentation.
Other Filtering Options
-----------------------
In addition to type filtering, FInf can also examine other properties
with which to exempt certain files from being displayed:
NEWER <object>
Display only objects which were created after or at the same time as
<object>.
OLDER <object>
Display only objects which were created before or at the same time
as <object>.
UPTO <date>
Display only those objects created UPTO a specified date. UPTO accepts
three formats:
DD-MMM-YY
TODAY/YESTERDAY/TOMORROW/MONDAY...SUNDAY/FUTURE
[n] TICK(s)/SECOND(s)/MINUTE(s)/HOUR(s)/DAY(s)/WEEK(s)/MONTH(s)/YEAR(s)
The integer [n] is optional, default is 1. The latter option is
extremely handy to cleanup your news directory.
E.g. FInf NEWS: -a -p -lf "Delete %s" UPTO 8 WEEKS BATCH
Make sure that your system clock contains the correct time! :-)
SINCE <date>
Display only object since a specified date. For information on the date
formats see UPTO.
LARGER <integer>
Display only files with a size smaller than or equal to <integer> bytes.
SMALLER <integer>
Display only files with a size smaller or equal than <integer> bytes.
SUB <string>
Display only objects containing at least one occurance of <string> in their
objectname.
NOI
Do not display .info files.
-d=DIRS
Display directories only.
-f=FILES
Display only files.
-a=ALL
Recursively displays the contents of any subdirectories in addition to
the files/dirs in the current directory. Wildcards in the path description
are not supported (yet), so for now this option will cause FInf to
recursively enter ALL encountered directories.
Formatting Options
------------------
These switches and keywords control the way in which FInf generates its
output:
BATCH
This will capture FInf's output into a uniquely named temporary file in
the T: directory, and subsequently will execute the file as a batch file
that will be deleted after completion.
This option is handy if you don't have unnamed pipes and something like
the ARP execute command which will execute any commands piped to it.
BLOCK=BLOCKS
This switch will cause FInf to display the number of blocks files occupy
on disk instead of their lengths. Note that for devices using the fast
filing system, this value will include any extension blocks.
DATES
This will cause FInf to print absolute dates instead of dates with
"Yesterday" of "Sunday" in them.
-lt=LONGTYPE
If specified, FInf will generate listings with a more verbose type
description. In order to create printing space for this, the date and
protection flags will not be displayed.
-nt=NOTYPE
If you use this switch, the contents of files will not be examined. The
type description will therefore not be displayed. The EXE, IMP, DOC,
IFF etc. filters won't work if NOTYPE is set. NOTYPE will cause FInf
to operate about twice as fast because of the decreased amount of work
it has to do for each file.
-na=NOANSI
This surpresses the generation of ANSI codes used by FInf to select bold
or italic font styles in the footer and such.
-nh=NOHEAD
Like with the normal List command, NoHead will stop FInf from generating
headers/footers with additional information on the examined files.
-ho=HEADONLY
This option is included to quickly simulate the unix DU command.
DU stands for Directory Usage, an example alias:
du = finf -ho -a []
NOX
This option removes extensions from the filenames. This might be handy
when you only wish to pass the filename root into the LFormat output.
E.g. FInf *.twiddle NOX LFormat "Rename %s.twiddle %s.twaddle" |
execute changes all .twiddle extensions into .twaddle extensions.
NOC
This simple option tells FInf to NOT print any filenotes (comments)
which might be attached to a file or directory. Note that when the
QUICK option is in effect filenotes are already been ignored.
-q=QUICK
In quick mode, FInf will display only filenames and any paths. No
lengths, flags, dates, comments or types will be printed, the type
filter switches will still function though. These bare (path+)file
names can be more readily used by programs you intend to feed FInf's
output to.
-p=PATH
If set, a full path will be pasted in front of any displayed filenames.
This option is useful e.g. in conjunction with the LFormat or ALL
switches.
-lf=LFORMAT <"...%s...%s...">
Works like List's LFormat option. Briefly, you can specify a string
with a "%s" in it (up to 8 %s expansions are supported), and where FInf
normally would have printed paths+file names, it displays the given
string with the path + file at the %s location. Useful for pasting
commands in front of filenames so you can pipe the output of FInf to a
batchfile, or directly to execute (if your shell supports this). E.g.
FInf LFORMAT "rename \"%s\" \"%s.doc\"" FILES DOC BATCH will append a
".doc" extension to all ASCII files found. Note: LFormatáautomatically
causes the Quick, NoAnsi and Nohead switch modes to be selected.
-nl=NOLINE [prefix]
This causes FInf not to print linefeeds between filenames. If you use
this together with a LFormat " %s" and a QUICK switch, you'll get a line
with file names separated by spaces. In the prefix position you may
optionally specify a string to be pasted in front of this line. This
will probably be the name of a command which requires a list of
filenames as its parameters. Note that this line will only be printed
if any filenames matching your wildcard specification were found. E.g.
FInf NOLINE "Ed " LFORMAT "\"%s\" " PATH FILES
will produce something like: Ed "ram:file1" "ram:doc1" "ram:readme"
General Information
-------------------
This program is Freely-Distributable, as opposed to Public Domain.
Permission is given to freely distribute this program provided you
include this documentation and any other related files, and no fee is
charged in excess of reasonable media and mailing costs.
Currently FInf supports the #,? and * wild cards. OS 2.0 wildcarding
will be implemented sometime in the future. Also high on the wish list
is a SORT option switch. If, during normal operation, there is only one
file matching the file/wildcard specification, and it is a program file,
some additional information about the number of hunks and the memory usage
will be displayed. FInf has a lot of switches, so there's a chance that
you might want to examine a file or directory that has the same name as
one of these switches. You can inform FInf that the object you
specified isn't a switch by putting quotes "" around it.
FInf is pure and can be made resident. Enjoy.
