It really sucks when your script does: cd `cat /sys/names/parent_directory` only to have it bomb out because cat can't open it. It sucks even worse if it actually *works* because some b0rked script had previously done: mkdir `cat /sys/names/parent_directory` Don't believe me? I've seen plenty of scripts that will do an 'rm $foo' where $foo is a parameter passed - so somebody runs the script with /usr/local/bin/foo -o /dev/null and later on you're trying to figure out why /dev/null is a 49 megabyte regular file.. ;)
