From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Good article. Rather than aliasing `cd ../.." etc. I've got this function in my setup:

up () {
	local x='' 
	for i in $(seq ${1:-1})
	do
		x="$x../" 
	done
	cd $x
}

This lets me do up 4 to go up 4 directories.

You could also do a "up" for one up "upp" for 2 and "upppp" for 4 because of fun

[–] executivechimp@discuss.tchncs.de 4 points 11 months ago

True. That is something that could be done.

Oh I really like this. I never had an alias for this since I need to do multiple backwards cds very rarely, but I might just copy this

[–] taladar@sh.itjust.works 3 points 11 months ago

I have the zsh option autopushd set which calls pushd in interactive shells for every cd, that way 90% of the time when I want to go back up to another path I can just use popd

[–] executivechimp@discuss.tchncs.de 1 points 11 months ago

Go for it. I've been using it for years without a problem.

I use Fish and have keybinds for previous and next directory, 99% of the time when going up in a directory it's to (one of) the previous directory/ies I was in

Holy shit

[–] beeng@discuss.tchncs.de 2 points 11 months ago (1 children)

Look into zoxide.

z direc

Will take you to the most used directory starting with "direc" eg "/home/me/random/directory"

[–] executivechimp@discuss.tchncs.de 2 points 11 months ago (1 children)

I've tried things like that before but never got on with them. I found when I had many projects with similar directory structures it was easy to end up in the wrong place and took more thought to get to the right place than just cding

[–] beeng@discuss.tchncs.de 1 points 11 months ago* (last edited 11 months ago)

The dir's are the same names or similar? A few extra key strokes to get the fullname should be easier than cd'ing back and forth.

There's also z foo "space" "tab" as per docs to get interactive list for matches.

But, just a suggestion!

What I use to automatically extend stuff like ls .... to ls ../../../..

function expand-dots() {
    local MATCH
    if [[ $LBUFFER =~ '(^| )\.\.\.+' ]]; then
        LBUFFER=$LBUFFER:fs%\.\.\.%../..%
    fi
}

function expand-dots-then-expand-or-complete() {
    zle expand-dots
    zle expand-or-complete
}

function expand-dots-then-accept-line() {
    zle expand-dots
    zle accept-line
}

zle -N expand-dots
zle -N expand-dots-then-expand-or-complete
zle -N expand-dots-then-accept-line
bindkey '^I' expand-dots-then-expand-or-complete
bindkey '^M' expand-dots-then-accept-line

(for zsh)
