Seriously the command line does it for me, gets me all hot and bothered ;). I just love having all the tools (including the shell itself) to be able to do what I need to do. Let me not even get started on awk and grep, though I think shortly I will write a *my top 5* command line tools or tools that a sysadmin should not live without (as I mainly handle backups this will differ greatly on both experience and preference so your mileage / kilomeratage may vary accordingly).
