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 com-
       mand described here, you must specify the full path /usr/bin/alias.  See the csh(1) reference page for a description of the  built-in  com-
       mand.

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

       [Tru64 UNIX]  Sets or lists tracked aliases.  [Tru64 UNIX]  Sets or lists exported aliases.

									  Note

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

OPERANDS

       Prints the alias definition on standard output.	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: Successful completion.	One of the name operands specified did not have an alias definition, or an
       error occurred.

EXAMPLES

       Change ls to give annotated output in columns: alias ls="ls -CF" Create a simple redo command to repeat previous  entries  in  the  command
       history	file:  alias r='fc -s' Cause du to use 1K units instead of the default 512-bytes: alias du=du -k 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: 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 vari-
       ables contain an invalid setting, the utility behaves as if none of the variables had been defined.  If set to a  non-empty  string  value,
       override the values of all the other internationalization variables.  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).  Determines the locale for  the  format
       and contents of diagnostic messages written to standard error.  Determines the location of message catalogues for the processing of LC_MES-
       SAGES.
