It’s a builtin shell variable that helps us to **[navigate to inside a directory without cd command][1]**. + +If you want to come back to previous directory then you have to type `cd ..`. + +If you want to go back to two directories then you have to type `cd ../..`. + +It’s normal in Linux but if you want to come back from 9th directory to 3rd directory, then it’s horrible to use cd command. + +What will be the solution for this. + +Yes, we have a solution in Linux for everything. We can go with bd command, to make easy this kind of situation. + +### What Is bd Command? + +bd command allow users to quickly go back to a parent directory in Linux instead of typing `cd ../../..` repeatedly. + +You can list the contents of a given directory without mentioning the full path `ls `bd Directory_Name``. It supports following other commands such as ls, ln, echo, zip, tar etc.. + +Also, it allow us to execute a shell file without mentioning the full path `bd p`/shell_file.sh`. + +### How To Install bd Command in Linux? + +There is no official distribution package for bd except Debian/Ubuntu. Hence, we need to perform manual method. + +For **`Debian/Ubuntu`** systems, use **[APT-GET Command][2]** or **[APT Command][3]** to install bd. + +``` +$ sudo apt install bd +``` + +For other Linux distributions. + +Download the bd executable binary file using **[wget command][4]**. + +``` +$ sudo wget --no-check-certificate -O /usr/local/bin/bd https://raw.github.com/vigneshwaranr/bd/master/bd +``` + +Set executable permission to the bd binary file. + +``` +$ sudo chmod +rx /usr/local/bin/bd +``` + +Append the below values in the `.bashrc` file. + +``` +$ echo 'alias bd=". bd -si"' >> ~/.bashrc +``` + +Run the following command to make the changes to take effect. + +``` +$ source ~/.bashrc +``` + +To enable auto completion, perform the following two steps. + +``` +$ sudo wget -O /etc/bash_completion.d/bd https://raw.github.com/vigneshwaranr/bd/master/bash_completion.d/bd +$ sudo source /etc/bash_completion.d/bd +``` + +We have successfully installed and configured the bd utility on the system. It’s time to test it. + +I’m going to take the below directory path for this testing. + +Run the `pwd` command or `dirs` command or `tree` command to know your current location. + +``` +daygeek@Ubuntu18:/usr/share/icons/Adwaita/256x256/apps$ pwd +or +daygeek@Ubuntu18:/usr/share/icons/Adwaita/256x256/apps$ dirs + +/usr/share/icons/Adwaita/256x256/apps +``` + +I’m currently in `/usr/share/icons/Adwaita/256x256/apps` and if i want to go to `icons` directory quickly then simple type the following command. + +``` +daygeek@Ubuntu18:/usr/share/icons/Adwaita/256x256/apps$ bd icons +/usr/share/icons/ +daygeek@Ubuntu18:/usr/share/icons$ +``` + +Even, you no need to type full directory name instead you can type few letters. + +``` +daygeek@Ubuntu18:/usr/share/icons/Adwaita/256x256/apps$ bd i +/usr/share/icons/ +daygeek@Ubuntu18:/usr/share/icons$ +``` + +`Note:` If there are more than one directories with same name up in the hierarchy, bd will take you to the closest.
