Workload Scheduler power users: You need rlwrap

If you use the Linux shell very much, you find its history functions very useful. You can recall previous commands very easily, just using the arrow keys.
If you use the Workload Scheduler command-line interfaces, conman and composer, you really miss the history. Sure there's the redo command, but its editing capability is limited to the last command you typed.


grep with color and context

GNU grep on Linux provides some interesting options. When you search for text in a log file, you can also highlight the text in color, and display two lines of context (the two lines preceding and succeeding the line containing the search expression). For example:
# grep --color -C 2 -E "res=failure" /var/log/audit/audit.log
