NAME

alias - create a function

SYNOPSIS

alias
alias [OPTIONS] NAME DEFINITION
alias [OPTIONS] NAME=DEFINITION

DESCRIPTION

alias is a simple wrapper for the function builtin, which creates a function wrapping a command. It has similar syntax to POSIX shell alias. For other uses, it is recommended to define a function.

fish marks functions that have been created by alias by including the command used to create them in the function description. You can list alias-created functions by running alias without arguments. They must be erased using functions -e.

NAME is the name of the alias
DEFINITION is the actual command to execute. The string $argv will be appended.

You cannot create an alias to a function with the same name. Note that spaces need to be escaped in the call to alias just like at the command line, even inside quoted parts.

The following options are available:

-h or --help displays help about using this command.
-s or --save Automatically save the function created by the alias into your fish configuration directory using funcsave.

EXAMPLE

The following code will create rmi, which runs rm with additional arguments on every invocation.

alias rmi="rm -i"
# This is equivalent to entering the following function:
function rmi --wraps rm --description 'alias rmi=rm -i'
    rm -i $argv
end
# This needs to have the spaces escaped or "Chrome.app..."
# will be seen as an argument to "/Applications/Google":
alias chrome='/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome banana'
