Define or display aliases.

Without arguments, `alias' prints the list of aliases in the reusable
form `alias NAME=VALUE' on standard output.

Otherwise, an alias is defined for each NAME whose VALUE is given.
A trailing space in VALUE causes the next word to be checked for
alias substitution when the alias is expanded.

Options:
-p[tab]print all defined aliases in a reusable format

Exit Status:
alias returns true unless a NAME is supplied for which no alias has been
defined.
