Review your most oft-used UNIX commands  IBM author Michael
Stutz lists several ways UNIX users can benchmark and increase
their productivity at the command line. One is to use the built
in history tool to review what programs you use the most, using
this command:   The result will be a list of commands you've
issued ordered by frequency. This is a fabulous way to identify
what commands could use a shorter alias; for example, if I type
ssh 20 times a day, it's worth setting up an alias like sshg to
get that done in fewer keystrokes. What commands show up the
most in your history? Let us know in the comments.
