The ALIAS command sets a new alias, displays an existing alias, or displays a list of all aliases.
If no arguments are supplied, ALIAS writes a list of all currently defined aliases to its standard output, one per line, in the form "name=value". If an alias name is supplied, ALIAS writes the value of that alias to standard output, in the form "name=value".
If a name and a value are both specified, ALIAS defines (or redefines) the alias with that name to have the given value.
Because of the syntax of the command, it is not possible to create an alias whose name contains an equals sign.
