Text Expansions for Fish

Typing consecutive dots after .. will automatically expand to ../.., then ../../.. and so on. It expands in place as you type to allow directory tab-completion to work. This can be useful with any command where you want to reference a parent directory that is more than one back. i.e. cd .... or vi .../Cargo.toml.

It's a little hard to see in the demo because it expands as you type, but cp ..../template/Makefile . is being typed.

Typing !! will expand to the previous command, similar to Zsh, Bash, and other shells. For example, if you type apt update you will likely see a permission error. You can then type sudo !! and it will expand to sudo apt update.

This can be especially useful if you don't want to retype a long command, or navigate around with the arrow keys. Or if you want to re-run a command as part of pipeline.

some-long-command -abcdef --long-option --another-long-option /a/long/path/to/somewhere

cat file1 file2 | !! | grep 'search-key' | wrap -s

Typing !$ will expand to the last argument. For example, if you searched packages with pacman and found nothing, you'd like to also search in the AUR.

pacman -Ss something

paru -Ss !$

Typing !* will expand to all arguments. For example, if you created some directories and then wanted to run chmod on them.

mkdir /tmp/a /tmp/b /tmp/c

chmod 700 !*

Install with Fisher:

Copy functions/* and conf.d/* to your $__fish_config_dir directory. Make sure to create them if they don't already exist.
