Re: Getting current directory

[oakley]

To get the current working directory, you could use:

$currdir = $ENV{PWD};

or

$currdir = $0; <-- (gives full execution path AND program name though)

Whoa, careful with that advice:

print $ENV{PWD}, "\n";
chdir('perl');

print $ENV{PWD}, "\n";
print `ls`;

Yeah, I wouldn't normally use the backticks there, but it proves my point. Also, $0 is spoofable. Cwd is a more reliable solution.

Update: You can spoof $0 by using symlinks, at least if your OS supports them.

Unlike argv[0] in C, $0 in Perl is not spoofable. See FindBin is broken (RE: How do I get the full path to the script executing?) for more details.

But $0 is certainly inappropriate for getting the full path to "the current working directory" or "where the script was called from" (though I could see misinterpretting this last phrase to mean the full path to the script). $0 often tells you the full path to where the script resides.
