Aliases in Nushell offer a way of doing a simple, textual replacement. This allows you to create a shorthand name for a longer command, including its default arguments.
For example, let's create an alias called
ll which will expand to
> alias ll = ls -l
We can now call this alias:
Once we do, it's as if we typed
ls -l. This also allows us to pass in flags or positional parameters. For example, we can now also write:
> ll -a
And get the equivalent to having typed
ls -l -a.
How to write an alias with Pipes
If you want to add a pipe to your alias you must must enclose it with parentheses which are a pair of round brackets ( ) used to mark off your set of commands with pipes.
alias lsname = (ls | get name)
Here is an alias with more than one pipe
alias lt = (ls | sort-by modified -r | sort-by type)
To make your alias persistent it must be added to your config.nu file.
For more details about how to persist aliases so that they're visible when you start up Nushell, see the configuration chapter.
