NAME
     alias - define or display aliases

SYNOPSIS
     alias [alias_name[=string] ...]

DESCRIPTION
     The alias utility creates or redefines alias definitions or writes the
     values of existing alias definitions to standard output. An alias
     definition provides a string value that replaces a command name when it
     is encountered.

     An alias definition affects the current shell execution environment and
     the execution environments of the subshells of the current shell. When
     used as specified by this specification, the alias definition will not
     affect the parent process of the current shell nor any utility
     environment invoked by the shell.

OPERANDS
     The following operands are supported:

     alias_name		 Write the alias definition to standard output.

     alias_name=string	 Assign the value of string to the alias alias_name.

     If no operands are given, all alias definitions will be written to
     standard output.

STDOUT
     The format for displaying aliases (when no operands or only name operands
     are specified) is:

	  "%s=%s\n", name, value

     The value string will be written with appropriate quoting so that it is
     suitable for reinput to the shell.

EXIT STATUS
     The following exit values are returned:

     0	  Successful completion.

     >0	  One of the name operands specified did not have an alias definition,
	  or an error occurred.

EXAMPLES
     1.	  Change ls to give a columnated, more annotated output:

	  alias ls="ls -CF"

     2.	  Create a simple "redo" command to repeat previous entries in the
	  command history file:

	  alias r='fc -s'

     3.	  Use 1K units for du:

	  alias du=du -k

     4.	  Set up nohup so that it can deal with an argument that is itself an
	  alias name:

	  alias nohup="nohup "
