alias: alias [-p] [name[=value] ... ] 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 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.
