I’ve just started a new series at IBM developerWorks looking at UNIX related system administration tricks. The aim is to cover some generic tips and help on a particular area (for example, process administration), and not only handle the tricks on different platforms, but look at ways of getting the same information through a script or alias if you manage UNIX machines in a heterogeneous network. In the first, Process Adminsistration, I look at the basics of using ps, how to get the same information out of different ps tools in different Unix variants, and how to kill, manage, and organize multiple processes within a shell.
