Scripts I wrote that I use all the time

I have a bunch of little scripts and aliases I've written over the years, but none are used more than these...

alias ..='cd ..'

alias ...='cd ../..'

alias ....='cd ../../..'

alias .....='cd ../../../..'

alias ......='cd ../../../../..'

alias .......='cd ../../../../../..'

up() { local d="" for ((i=1; i<=$1; i++)); do d="../$d" done cd "$d" }

up 2, up 3 etc.

Does zsh support this out-of-the-box? Because I definitely never had to setup any of these kinds of aliases but have been using this shorthand dot notation for years.

I have setup a shortcut: alt+. to run cd.., it's pretty cool.

I also aliased - to run cd -

Yes it does.

Not on my Mac.

    zsh: permission denied: ..
    zsh: command not found: ...

I need this *so* often that I programmed my shell to execute 'cd ..' every time I press KP/ i.e. '/' on the keypad, without having to hit Return.

Other single-key bindings I use often are:

KP* executes 'ls'

KP- executes 'cd -'

KP+ executes 'make -j `nproc`'

but alt-. in bash is used for pasting the last argument to the previous command into the current one.

fish lets you cd to a folder without 'cd' although you still need the slashes. I use it all the time.

    c $> pwd
    /a/b/c
    c $> dir1
    dir1 $> ..
    c $> ../..
    / $>

How? Readline macros?

It's an oh-my-zsh thing.
