Insert the last argument of the previous terminal command

Wed, 20 May 2026 00:00:00 +0000

Today I learned that you can use !$ in bash to use the last argument of the previous command.

The simplest example is:

mkdir /some/long/path
cd !$

You can do something similar in powershell by using a PSReadline binding:

Set-PSReadLineKeyHandler -Chord "Alt+." -Function YankLastArg

Shell Check

Today I learned about ShellCheck which is essentially a linter for bash scripts.

You can try it on the website but I recommend installing the vscode extension. I like that you can look up the rationale for each of the rules so it’s a great way to learn some best practices for bash scripts.
