alias - create a function¶
alias alias [--save] NAME DEFINITION alias [--save] NAME=DEFINITION
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
NAMEis the name of the alias
DEFINITIONis the actual command to execute.
$argv, so that all parameters used with the alias are passed to the actual command.
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
Saves the function created by the alias into your fish configuration directory using funcsave.
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'
