I have installed git, github, and various python utilities ...

Pythonista gits tend to like *nix-ish utilities, so I wouldn't be surprised if one of those installs smuggled the Windows port of the GNU utilities aboard. From my Windows system:

c:\@Work\Perl\monks>which which.exe
c:\UnxUtils\wbin\which.exe
[download]

And git on Windows comes with its own perl, which on my system is version 5.26.2. That would explain the extra perl in the path.

ScarletObsidian: where perl will list the location of all the perls in your path, and I would assume one will be under git's usr/bin subfolder. And now I think of it, if you are running the git console then calling which perl will list /usr/bin/perl, which is what you reported in your first post.

There you'll have which and a Perl installation and Unix paths notation.

That doesn't effect the normal cmd.exe unless you change PATH to point to the git utilities. ( I never tried this)

Anyway perldoc -l MODUL will point you to your Perl's installation directory.

For instance the doc location of a core module like warnings always works.

update

s/-t/-l/

update

Fired up my Win box and inside cmd.exe it works

D:\>perldoc -l warnings
C:\Perl_524\lib\warnings.pm
[download]

But seems that git-bash comes without perldoc

$ perldoc -l warnings
Can't locate Pod/Perldoc.pm in @INC ...
[download]

But the following works on both variations, provided you swap ' and " accordingly for cmd.exe

$ perl -Mwarnings -e 'print $INC{"warnings.pm"}'
/usr/share/perl5/core_perl/warnings.pm
[download]

D:\>perl -Mwarnings -e "print $INC{q'warnings.pm'}"
C:/Perl_524/lib/warnings.pm
[download]

I took a look at my path variable. Turns out I have something called MinGW, so MINimalist Gnu for Windows, installed. It shows up right after Brackets' Path entry and before a whole stack of earlier Strawberry perl entries.

 which which returns:  usr/bin/which

 which perl returns: usr/bin/perl

perl -e "print$^X" returns: perl

Note, this is only true if I open a default windows terminal; if I use the portable shell executable packaged with portable Strawberry perl, which perl gives me the correct file path (to my desktop, atm, where I unpacked portable Strawberry perl).
