\subsection alias-description 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 <a href='#function'>function</a>.
|
|
|
|
`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 <a href='#funcsave'>funcsave</a>.
|

\subsection alias-example Example
|
|
|
|
The following code will create `rmi`, which runs `rm` with additional arguments on every invocation.
|
|
|
|
\fish
|
|
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'
|
|
