alias - Defines or displays aliases
alias [-tx] [alias-name[=string...]]
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.
Interfaces documented on this reference page conform to
industry standards as follows:
Refer to the standards(5) reference page for more information
about industry standards and associated tags.
[Tru64 UNIX] Sets or lists tracked aliases. [Tru64
UNIX] Sets or lists exported aliases.
See the ksh(1) reference page for a description of tracked
and exported aliases.
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.
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
[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.
[Tru64 UNIX] If you use either the -t option or the -x
option, you must use at least one alias-name or aliasname=string
[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
[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.
The following exit values are returned: Successful completion.
One of the name operands specified did not have an
alias definition, or an error occurred.
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 [Toc] [Back]
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 variables
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_MESSAGES.
