Theory: Making custom commands with aliases

Lesson notes

• alias to view all aliases
• alias name='command' to create a new alias named name for the command command (e.g. alias lss='ls | sort -r')
• unalias name to unalias an alias named name

Some useful aliases

• alias c='clear' — clears the screen with c
• alias ..='cd ..' - quickly go one level up with ..
• alias h='history' — quickly access history with h
