What does 'cd -' stand for?

Question

In a bash shell script today I noticed the below command at the end of the script. I know what is cd but I am unaware of the significance of a dash after it.

Answer 1

From the man found here : http://ss64.com/bash/cd.html

Quickly get back
$ cd - 

Answer 2

cd - brings you back to the last directory.

$ cd ~/Desktop
$ pwd
/Users/daknok/Desktop
$ cd /
$ pwd
/
$ cd -
$ pwd
/Users/daknok/Desktop

Answer 3

If a single dash is specified as the argument, it will be replaced by the value of OLDPWD.

The OLDPWD is set by cd command and it is the previous working directory.

Answer 4

“ Current Directory “ Is what the bash cd terminal command means. It means “ keep me in this directory “

Answer 5

cd - returns to the directory you were previously.

For instance:

marcelo@marcelo:~$ cd /opt
marcelo@marcelo:/opt$ cd /usr/bin
marcelo@marcelo:/usr/bin$ cd -
/opt
marcelo@marcelo:/opt$ 

I was in /opt, changed to /usr/bin, and then went back to /opt with cd -

Answer 6

cd - bring you back to the last directory you were. e.g.

cd ~/Documents
cd ~
cd /

Now you are in '/', and if you run 'cd -' you will be in '~'. BTW, run 'cd -' once again, you will return to '/' but not '~/Documents'
