Some Useful Shell Aliases

These are just some shell aliases that I find personally useful, and tend to drop onto machines I'm using (if they're not already installed thanks to the default Bash/ZSH configuration).

# Useful aliases
alias ls="ls --color"
alias ll="ls -l"
alias l="ls -al"
alias less="less -R"  # for color preservation (sometimes)
alias c="clear"
alias newscreen="screen -D -R"
