Where do I find things?

If you are trying to find a program, log into the shell. Typing “whereis program”, where ‘program’ is the program you are looking for, will show you one or more possibilities for what you are looking for. If you have more than one copy of a program, say one in /usr/bin and another in /usr/local/bin/, typing “which program” will show you which one will be called first. If you can’t find it at all, typing “locate program” will show you everyfile that matches “program.” Some of the most common programs are:

• /usr/sbin/sendmail
• /usr/bin/perl
• /bin/mail
• /usr/bin/php
