I found this in Ubuntu repos, and consider it better than timeout.

write the output of a command to /var/log/user.log… each line will contain $USER, making this easy to grep for.

This command is useful if you want to copy the output of a series of commands to a file, for example if you want to pastebin the output from ‘uname -a’, ‘lspci -vvv’ and ‘lsmod’ for video driver trouble-shooting on your favorite Linux forum.

Empty a file

This one is for those who know the “touch” command. Hope all of us do not follow a  command just because it is on one of the popular site without trying to understand the command and the output.

Bash Script Beautifier

Today I was working on a bash script written by someone else. And the script was maintained since long and had actually become quite big and there was no indentation followed.

In general, this is actually not better than the “scrot -d4” command I’m listing it as an alternative to, so please don’t vote it down for that.

I’ve found xwd handy on boxen that I don’t want to (or am not allowed to) install packages on.
