What bash aliases can't you live without?

#bash #alias #discuss

Here's some of mine:

Change up 1, 2 or 3 directories:

alias .....='cd ../../../..'
alias ....='cd ../../..'
alias ...='cd ../..'
alias ..='cd ..

Example:

mcrowe in /tmp/level-1/level-2/level-3/level-4/level-5 
$ ....
mcrowe in /tmp/level-1/level-2 
$

Grep history:

alias gh='history | grep --colour=auto'

Strip line numbers from history "history cut"

alias hc="history | cut -b 8-

ps commands:

alias psa='ps faux'
alias psag='ps faux | grep

psa: shows detailed output:

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root         2  0.0  0.0      0     0 ?        S    Jan15   0:00 [kthreadd]

psag: Grep psa output:
