It's a port of GNU tar, so if you're comfortable with that, it should be fairly close. Any significant differences will likely be related to binary versus text file mode issues that sometimes crop up in windows but don't exist in unix, commandline parameter quoting and shell expansion issues in the Windows commandline shell(in short, the DOS-style commandline shell handles neither quotes nor expansion, any programs that want that behavior must do it themselves), or filenames that are possible on UNIX but not windows, or case sensitivity issues(it's possible to have file, File, and FILE as three separate files in UNIX, Windows will only let you have one of them), permissions, links(tar can store symlinks, which only a few odd Server versions of Windows can handle), etc, etc.

file::which
File::Which(3) User Contributed Perl Documentation File::Which(3)
NAME
File::Which - Portable implementation of the `which' utility
SYNOPSIS
use File::Which; # exports which()
use File::Which qw(which where); # exports which() and where()
my $exe_path = which('perldoc');
my @paths = where('perl');
- Or -
my @paths = which('perl'); # an array forces search for all of them
DESCRIPTION
"File::Which" was created to be able to get the paths to executable programs on systems under which the `which' program wasn't implemented
in the shell.
"File::Which" searches the directories of the user's "PATH" (as returned by "File::Spec->path()"), looking for executable files having the
name specified as a parameter to "which()". Under Win32 systems, which do not have a notion of directly executable files, but uses special
extensions such as ".exe" and ".bat" to identify them, "File::Which" takes extra steps to assure that you will find the correct file (so
for example, you might be searching for "perl", it'll try perl.exe, perl.bat, etc.)
Steps Used on Win32, DOS, OS2 and VMS
Windows NT
Windows NT has a special environment variable called "PATHEXT", which is used by the shell to look for executable files. Usually, it will
contain a list in the form ".EXE;.BAT;.COM;.JS;.VBS" etc. If "File::Which" finds such an environment variable, it parses the list and uses
it as the different extensions.
Windows 9x and other ancient Win/DOS/OS2
This set of operating systems don't have the "PATHEXT" variable, and usually you will find executable files there with the extensions
".exe", ".bat" and (less likely) ".com". "File::Which" uses this hardcoded list if it's running under Win32 but does not find a "PATHEXT"
variable.
VMS
Same case as Windows 9x: uses ".exe" and ".com" (in that order).
Functions
which($short_exe_name)
Exported by default.
$short_exe_name is the name used in the shell to call the program (for example, "perl").
If it finds an executable with the name you specified, "which()" will return the absolute path leading to this executable (for example,
/usr/bin/perl or C:PerlBinperl.exe).
If it does not find the executable, it returns "undef".
If "which()" is called in list context, it will return all the matches.
where($short_exe_name)
Not exported by default.
Same as "which($short_exe_name)" in array context. Same as the `where' utility, will return an array containing all the path names matching
$short_exe_name.
BUGS AND CAVEATS
Not tested on VMS or MacOS, although there is platform specific code for those. Anyone who haves a second would be very kind to send me a
report of how it went.
File::Spec adds the current directory to the front of PATH if on Win32, VMS or MacOS. I have no knowledge of those so don't know if the
current directory is searced first or not. Could someone please tell me?

Originated in modperl-2.0/lib/Apache/Build.pm. Changed for use in DocSet (for the mod_perl site) and Win32-awareness by me, with slight
modifications by Stas Bekman, then extracted to create "File::Which".
Version 0.04 had some significant platform-related changes, taken from the Perl Power Tools `which' implementation by Abigail with
enhancements from Peter Prymmer. See <http://www.perl.com/language/ppt/src/which/index.html> for more information.
