Do you know the Alias command?

An important shell feature is the ability to create aliases or shortcuts for commands. It can be used to simplify commands with many options or execute multiple processes in sequence. &feature=youtu.be The alias creates these shortcuts:

# alias psuira='ps aux |grep uira'

# psuira

root 1200 0.0 1.3 5040 1752 ? S 10:17 0:00 sshd: uira@pts/4

uira 1201 0.0 1.3 2872 1656 pts/4 S 10:18 0:00 -bash

root 2657 0.0 0.4 1764 552 pts/4 S 21:19 0:00 grep uira

In this example the alias psuira corresponds to the commands ps aux | grep uira.

The list of aliases can be displayed with the alias command without any parameters:

# alias

alias +='pushd .'

alias -='popd'

alias ..='cd ..'

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

alias beep='echo -en "\007"'

alias dir='ls -l'

alias l='ls -alF'

alias la='ls -la'

alias ll='ls -l'

alias ls='/bin/ls $LS_OPTIONS'

alias ls-l='ls -l'

alias lsw='ls -l |more'

alias md='mkdir -p'

alias o='less'

alias psuira='ps aux |grep uira'

alias rd='rmdir'

alias rehash='hash -r'

alias unmount='echo "Error: Try the command: umount" 1>&2; false'

alias which='type -p'

alias you='yast2 online_update'
