Alias often...

It's often very frustrating to retype shell commands over and over.  One thing that I sometimes forget to do is to create aliases for common commands.  I just added an alias for something I do quite often - search the shell history for some command I typed in either the previous or current session.

Edit your config file of choice (I updated .profile) and add the following:

alias hgrep='history | grep'

Now I can just type hgrep along with the search phrase of choice.  ie,

somemachine:someuser:/opt/somedir/home/username: hgrep 'start'
  235  ../bin/startup.sh
  250  ../bin/startup.sh
  256  ../bin/startup.sh
 1023  hgrep 'startserv'
 1024  hgrep 'start'
