"Do you know the whereis command, then?"

On most systems, the commands whereis and which are simply aliases to "type", a bash built-in shell command. This is useful to know when you work on SCO or Solaris and simply have bash, without the default linux bashrc and bash_profile files.

These only search your current $PATH, too. If you su to root (very likely, if you are telnet/ssh'ing in, since remote root logins SHOULD be disabled), the $PATH var will be the users path. Try "su -". "su -" switches users AND runs their login scripts. "su - ronelson", for instance, switches to ronelson and runs his login scripts. This is great when a user on your system calls and tells you something isn't working. Since you are root, you don't need to ask for their password. Great when their login scripts put them in a menu that pulls info based on the login name.
