alias(1)
NAME
  alias - Defines or displays aliases

SYNOPSIS
  alias [-tx] [alias-name[=string...]]

				     Note

       The C shell has a built-in version of the alias command.	 If you are
       using the C shell, and want to guarantee that you are using the
       command described here, you must specify the full path /usr/bin/alias.
       See the csh(1) reference page for a description of the built-in
       command.

STANDARDS
  Interfaces documented on this reference page conform to industry standards
  as follows:

  alias:  XCU5.0

  Refer to the standards(5) reference page for more information about
  industry standards and associated tags.

OPTIONS
  -t  [Tru64 UNIX]  Sets or lists tracked aliases.

  -x  [Tru64 UNIX]  Sets or lists exported aliases.

				     Note

       See the ksh(1) reference page for a description of tracked and
       exported aliases.

OPERANDS
  alias-name
      Prints the alias definition on standard output.

  alias-name=string
      Assigns the value of string to the alias alias-name.

  If no options and no operands are specified, all alias definitions are
  printed on standard output.

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
  described, the alias definition will not affect the parent process of the
  current shell nor any utility environment invoked by the shell.

NOTES
  [Tru64 UNIX]	This reference page describes the creation and maintenance of
  aliases.  See the Command Aliasing section of the ksh(1) or sh(1p)
  reference pages for the description of alias substitution.

RESTRICTIONS
  [Tru64 UNIX]	If you use either the -t option or the -x option, you must
  use at least one alias-name or alias-name=string operand.

  [Tru64 UNIX]	Aliasing is performed when scripts are read, not while they
  are executed.	 Therefore, for an alias to take effect, the alias definition
  command has to be executed before the command that references the alias is
  read.

  [Tru64 UNIX]	Aliases can be used to redefine special built-in commands but
  cannot be used to redefine the reserved words listed in the ksh(1)
  reference page.

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 annotated output in columns:
	    alias ls="ls -CF"

   2.  Create a simple redo command to repeat previous entries in the command
       history file:
	    alias r='fc -s'

   3.  Cause du to use 1K units instead of the default 512-bytes:
	    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 "

ENVIRONMENT VARIABLES
  The following environment variables affect the execution of alias:

  LANG
      Provides a default value for the internationalization variables that
      are unset or null. If LANG is unset or null, the corresponding value
      from the default locale is used.	If any of the internationalization
      variables contain an invalid setting, the utility behaves as if none of
      the variables had been defined.

  LC_ALL
      If set to a non-empty string value, override the values of all the
      other internationalization variables.

  LC_CTYPE
      Determines the locale for the interpretation of sequences of bytes of
      text data as characters (for example, single-byte as opposed to
      multibyte characters in arguments).

  LC_MESSAGES
      Determines the locale for the format and contents of diagnostic
      messages written to standard error.

  NLSPATH
      Determines the location of message catalogues for the processing of
      LC_MESSAGES.
