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 aliasDEFINITION
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'
