• apropos – Often a wrapper for the “man -k” command, the apropos command is used to search all manual pages for the string specified. This is often useful if one knows the action that is desired, but does not remember the exact command or page name. In simple it’s search man pages for topic.

• egrep – Search for a pattern using extended regular expressions. egrep is essentially the same as running grep with the -E
