Schedule a script or command in x num hours, silently run in the background even if logged out
This is helpful for shell scripts, I use it in my custom php install script to schedule to delete the build files in 3 hours, as the php install script is completely automated and is made to run slow. Does require at, which some environments without crontab still do have. You can add as many commands to the at you want. Here's how I delete them in case the script gets killed. (trapped) atq |awk '{print $1}'|xargs -iJ atrm J &>/dev/null

Search google and show only urls
Get the first 10 google results form a querry, but showing only the urls from the results. Use + to search diferent terms, ex: commandlinefu+google .

recursive search and replace old with new string, inside files
Search and replace recursively. :-) Shorter and simpler than the others. And allows more terms: replace old new [old new ...] -- `find -type f`

quickly backup or copy a file with bash
less symbols, tab completion. including # export SIMPLE_BACKUP_SUFFIX="_`date +%F`" in your .bashrc provides you to easily timestamp your files

list block devices
Shows all block devices in a tree with descruptions of what they are.

Factorial With Case
Computes factorials.

list files recursively by size

Monitor connection statistics with netstat and watch

Ultimate current directory usage command
Based on the MrMerry one, just add some visuals and sort directory and files

Using a single sudo to run multiple && arguments
This will also work with bash instead of sh shell sudo bash -c 'apt update -y && apt upgrade -y'
