Full Discussion: Test -e not working as expected (by me)
Top Forums UNIX for Advanced & Expert Users Test -e not working as expected (by me) Post 302938169 by MadeInGermany on Thursday 12th of March 2015 03:43:43 PM

I did some tracings.
Indeed test -L does an lstat() i.e. does not try to follow a symlink.
test -e does either a stat() or an access() i.e. follows a symlink and a symlink's symlink... This is meant with "resolve".
In order to test for anything, you need test -L "$file" || test -e "$file".

perlio::via::symlink5.18

symlink(3)						User Contributed Perl Documentation						symlink(3)

NAME

       PerlIO::via::symlink - PerlIO layers for create symlinks

SYNOPSIS

	open $fh, '>:via(symlink)', $fname;
	print $fh "link foobar";
	close $fh;

DESCRIPTION

       The PerlIO layer "symlink" allows you to create a symbolic link by writing to the file handle.

       You need to write C"link $name" to the file handle. If the format does not match, "close" will fail with EINVAL.
