alias [ -grm ] [ name[=value] ] ...
With no arguments, print the list of aliases in the
form name=value on the standard output. For each
name with a corresponding value, define an alias
with that value. A trailing space in value causes
the next word to be checked for alias substitution.
If the -g flag is present, define a global alias;
global aliases are expanded even if they do not
occur in command position. For each name with no
value, print the value of name, if any. If only
the -g or the -r flags are given only global or
regular aliases are listed. If the -m flag is given
the arguments are taken as patterns (they should be
quoted to preserve them from being interpreted as
glob patterns) and the aliases matching these pat-
terns are printed. The exit status is nonzero if a
name (with no value) is given for which no alias
has been defined.
unalias [ -m ] name ...
The alias definition, if any, for each name is
removed. With the -m flag the arguments are taken
as patterns (should be quoted) and all aliases with
matching names are removed.
