Display CPU usage in percentage

Using the output of 'ps' to determine CPU usage is misleading, as the CPU column in 'ps' shows CPU usage per process over the entire lifetime of the process. In order to get *current* CPU usage (without scraping a top screen) you need to pull some numbers from /proc/stat. Here, we take two readings, once second apart, determine how much IDLE time was spent across all CPUs, divide by the number of CPUs, and then subtract from 100 to get non-idle time.

Hide the name of a process listed in the `ps` output

exec -a $NAME $COMMAND $ARGS

`your_cmd -erase_all_files` is the real process, but harmless-looking getty appears in the process table.

Never actually had a need to do this, but interesting nonetheless... Tested in bash, dash.

-a $NAME

"pass NAME as the zeroth argument to COMMAND", i.e. customise the name of the process (as commonly seen with `ps`)

Show WebSphere AppServer uid|pid|cell|node|jvms

Tested in bash on AIX & Linux, used for WAS versions 6.0 & up. Sorts by node name.

Useful when you have vertically-stacked instances of WAS/Portal. Cuts out all the classpath/optional parameter clutter that makes a simple "ps -ef | grep java" so difficult to sort through.
