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".

lchgrp

LCHGRP(3)								 1								 LCHGRP(3)

lchgrp - Changes group ownership of symlink

SYNOPSIS

       bool lchgrp (string  $filename, mixed  $group)

DESCRIPTION

	Attempts to change the group of the symlink $filename to $group.

	Only the superuser may change the group of a symlink arbitrarily; other users may change the group of a symlink to any group of which that
       user is a member.

PARAMETERS

	      o $filename
		- Path to the symlink.

	      o $group
		- The group specified by name or number.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Changing the group of a symbolic link

	      <?php
	      $target = 'output.php';
	      $link = 'output.html';
	      symlink($target, $link);

	      lchgrp($link, 8);
	      ?>

NOTES

       Note

	      This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.

       Note

	      When safe mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as  the  script
	      that is being executed.

       Note

	      This function is not implemented on Windows platforms.
