Cd Command

cd is a shell built-in command and stands for "changes directory".

You can point to directories in two ways:

  1. Absolute Paths: Like /home/devtalks/lpic1/lesson1
  2. Relative Paths: Like lpic1/lesson1 In this case, we are not adding the / in the beginning so the bash will try to find lpic1 directory where we are (local / relative)

You can check your current working directory with the pwd command.

Tips and Tricks

Toggle Between Directories:

Use cd - to switch back to the previous directory.

cd /path/to/first-directory
cd /path/to/second-directory
cd -  # returns to /path/to/first-directory

Go Home Quickly:

Use cd ~ or just cd to return to your home directory.

cd ~  # or just: cd

Move Up One Directory:

Use cd .. to move up one level.

cd ..      # moves up one directory level
cd ../../  # moves up two directory levels

Navigate to Root:

Use cd / to go to the root directory.

cd /  # navigates to the root directory

Visit Another User's Home:

Use cd ~username to access another user's home directory

cd ~ali  # navigates to Ali's home directory

Leverage Tab Completion:

Type part of a directory name and press Tab to auto-complete it.

cd /usr/lo[Press Tab]  # auto-completes to /usr/local/

Reuse Last Argument:

Use cd !$ to reuse the last argument from the previous command.

echo /some/directory/path
cd !$  # equivalent to: cd /some/directory/path

Quick Access with CDPATH:

Set CDPATH for quick navigation to frequent directories.

export CDPATH=.:~/projects:/var/log # seperated with colon
cd myproject  # jumps to ~/projects/myproject if it exists

Note: For persistent usage, you can add this to your .bashrc file.(use absolute path)

Enable AutoCD for Implicit Navigation:

Use the shopt command to enable or disable automatic directory navigation without explicitly typing cd.

shopt -s autocd  # enable auto cd
/path/to/dir     # automatically navigates to /path/to/dir
shopt -u autocd  # disable auto cd

Note: For persistent usage, you can add this to your .bashrc file.

Use Directory Stack:

Use pushd to save directories and popd to return.

pushd /path/to/directory1
pushd /path/to/directory2
popd  # returns to /path/to/directory1
