resolving symbolic links in a pathname

PerlDisciple has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks,

There's a resolvepath system call in Unix (man pages section 2, unistd.h on Solaris) that resolves all the symbolic links of its pathname argument. Does anyone know of a way, via CPAN module or otherwise, to get the same functionality in Perl?

Regards,
PerlDisciple

I think you want `abs_path` in Cwd. -- Randal L. Schwartz, Perl hacker	[reply] [d/l]

Pardon the not-very-useful wild guess, but wasn't there a nice example program in some old Camel Book that would print out an output like `/home/mjd/foo.c /home/mjd/bar/baz/foo.c /home/mjd/bar-1.0/baz/foo.c /userhomes/m/j/mjd/bar-1.0/baz/foo.c /mnt/homevol/m/j/mjd/bar-1.0/baz/foo.c` [download] as it progressively resolved the symlinks in higher and higher components of a path? I thought it might have been one of those abandoned items in the Perl source `eg/` directory, but I couldn't find it there, so the Camel Book was my next guess. Addendum: This looks kinda interesting too. -- Mark Dominus Perl Paraphernalia	[reply] [d/l]

You might be thinking of my column about expanding symbolic links. -- Randal L. Schwartz, Perl hacker	[reply]

Yeah, in the pink Camel Book. I posted it here some time ago: Re: Following symlinks manually (historical code) ;-) --shmem _($_=" "x(1<<5)."?\n".q·/)Oo.

Funny, Googling perl symbolic pathname turned up File::Find fairly quickly. See `$File::Find::fullname` in that document for something that sounds like it would work for you.	[reply] [d/l]
