Synopsis:
$unlink(<file> [<file> ...])
Technical:
This function is roughly equivalent to the C library unlink() call. It
deletes the given files from the filesystem. Standard shell tilde-
expansion is permitted.
Practical:
This function is used to delete files. One possible use might be to
remove old client log files. Any tilde (~) found in the filename is
converted to the user's home directory.
Returns:
0 successful
>0 number of files that could not be unlinked
Examples:
$unlink(~/.ircmotd) force client to see client motd on next startup
$unlink(/etc/passwd) will probably return >0
Restrictions:
Naturally, filesystem permissions will limit what the user can and cannot
unlink.
