Aliases are defined with alias <rhs>=<cmd> so that <cmd>
is substituted for <rhs> - not unlike a macro substitution.
Aliases are usually placed in .bashrc file in your home directory.
Some examples:
alias rm="rm -i"
alias vi="gvim"
alias ls="ls -F --color=auto"
alias proj="cd ~/cs453/prog5"
Then typing the command proj takes you to the directory ~/cs453/prog5. If for some reason you need to remove an alias, just use
the unalias command.
