A few well chosen words to BASH. . .  

Many, many small utils available from BASH

    grep -i dedicated -A4 -B3  Negotiator.log

The Pipe

• Send the output of one programme into another:

    ps auxw | grep -i vnc
        # ...who is using VNC on Man2e?

• Who is hogging all the disk space?

    root@man2e> du -s /home/* | sort -nr 

Looping

• BASH is a full programming language:

    for i in *.sh; do echo $i; dos2unix -n $i $i.unix; done
