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 - 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. SEE ALSO
chgrp(3), lchown(3), chown(3), chmod(3). PHP Documentation Group LCHGRP(3)
