Linux (commonly pronounced LIH-N?ks in English; variants exist) is a Unix-like computer operating system. Linux is one of the most prominent examples of free software and open source development: typically all underlying source code can be freely modified, used, and redistributed by anyone.

Showing the difference between runlevels

If you want to quickly find out what the difference between runlevels in linux (say if you want to switch from a GUI to a non-gui) you can use

# /sbin/chkconfig --list

This will print columns showing you what is on and what is off for each runlevel. Neat but it's too much information, I just want to compare 5 and 3. Here is how you can clean that up:

# /sbin/chkconfig --list|awk '{printf("%-19s%-19s%-19s\n", $1,$5,$7)}'

This gives the output nice and still column formatted
