I can navigate down in directory using cd in the terminal. How do I navigate back up if I go too far?

cd .. will bring you back exactly one directory up.

You can string together those to go up multiple directories, e.g. up 3

cd ../../..

Instead of typing cd .. multiple times, what you could to is to place the function bellow into your .bashrc somewhere at the top, save .bashrc, and run source .bashrc or just close and reopen a terminal. Now, you have a function that does cd.. exactly how many times you told it to.

function goUp {
  num=$1
  while [ $num -ne 0  ];do
    cd ..
    num=$((num-1))
  done
}

Demo:

$ cd /usr/share/backgrounds/                                                  

backgrounds:$ goUp 2

usr:$ 

Alternatively:

goup(){ 
    cd $(n=$1 awk 'BEGIN{
        for(i=1;i<=ENVIRON["n"];i++) 
            printf "../"}';) 
}

Note that such method brings you back along the symlinks. Here's what I mean:

$ namei "$PWD" 
f: /home/user/VirtualBox VMs/CentOS
 d /
 d home
 d user
 l VirtualBox VMs -> /mnt/ubuntu/vboxvms
   d /
   d mnt
   d ubuntu
   d vboxvms
 d CentOS

$ goup 2
$ pwd
/home/user

  • Added some more info, check it. – Sergiy Kolodyazhnyy Nov 28 '15 at 23:36
  • That could be just for i in $(seq "$1"); do cd ..; done. – deltab Nov 29 '15 at 2:08
  • @deltab true, could be done as well . . . .But I prefer using while + counter to simulate a for loop. I've asked a relevant question before on U&L site – Sergiy Kolodyazhnyy Nov 29 '15 at 2:14

I found a simple way to go up.

cd ../

./ means current directory

../means one level up directory

  • Upvote because I did not know that the cd .. stands for cd ../, I thought it would be just like cd.. in Windows and did not understand the space in between until now. – questionto42 Feb 11 at 14:48

    @questionto42 Yeah, .. is same as ../, as well as . vs ./. You can even join multiple slashes like this: .///. It's still same as .. There are also other cd tricks, like cd -, which will change the directory to the previous one. But that's a bit off topic :) – adazem009 Feb 11 at 21:23

you can use popd and pushd too, to "checkpoint" or "bookmark", or as I tend to describe it; "set a spawn-point":

pushd ./ # set the spawn point to the current folder ./

go to another directory, like cd .. or whatever

popd     # get back to where we set pushd

This is, hopefully something useful for someone,

Have a great day reader!
