\section alias alias - create a function
\subsection alias-synopsis Synopsis
\fish{synopsis}
alias NAME DEFINITION
alias NAME=DEFINITION
\endfish
\subsection alias-description Description
`alias` is a simple wrapper for the `function` builtin. It exists for backwards compatibility with Posix shells. For other uses, it is recommended to define a <a href='#function'>function</a>.
`fish` does not keep track of which functions have been defined using `alias`. 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 in the commandline _even inside the quotes_.
\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
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'
\endfish
