Intro To 'cd' Command In Linux

2023-04-25 - By Robert Elder

     I use the 'cd' command to change the current working directory. Whenever I use the 'cd' command, the output from running the 'pwd' command changes:

pwd

     Outputs:

/home/robert/important

cd my-favourite-directory

pwd

     Now outputs:

/home/robert/important/my-favourite-directory

     I can also see that the value of the shell variable 'PWD' changes as well:

echo $PWD

     Outputs:

/home/robert/important/my-favourite-directory

     I can provide an absolute path to the 'cd' command like this:

cd /home/robert/important/my-other-directory

pwd

     Outputs:

/home/robert/important/my-other-directory

     I can also provide a path that's relative to my current working directory. This command will move up one directory:

cd ..

pwd

     Outputs:

/home/robert/important

     And this command will move up two directories:

cd ../..

pwd

     Outputs:

/home

     And that's why the 'cd' command is my favorite Linux command.
