How to create shell aliases to speed up your workflow

Shell Aliases

Aliases are shortcuts: you define a short name for a longer command. They save keystrokes and reduce typos for commands you run dozens of times a day.

Alias syntax

alias gs='git status'
alias gp='git push'
alias gc='git commit -m'

No spaces around =. Use single quotes to prevent the shell from expanding variables at definition time.

Practical developer aliases

alias ll='ls -lah'
alias ..='cd ..'
alias ...='cd ../..'
alias cls='clear'
alias serve='python3 -m http.server 8000'

Making aliases permanent

echo "alias ll='ls -lah'" >> ~/.bashrc
source ~/.bashrc

Removing an alias in the current session

unalias gs

When to use a function instead

Aliases cannot accept arguments. If you need logic or parameters, use a function:

mkcd() {
  mkdir -p "$1" && cd "$1"
}
# Usage: mkcd new-project

Add functions to .bashrc the same way as aliases.
