Linux Up Command for Multilevel Directories in Shell-Bash

The up command in Linux is a convenient way for navigating multiple levels of directories quickly. This command allows users to move up one or more levels in the directory hierarchy with a single command instead of using repetitive cd .. commands.

Syntax

The syntax of the up command is as follows:

up [number]

Here, number is the number of levels to move up in the directory hierarchy. By default, number is set to 1.

Usage

To use the up command, first, you need to install the up script. This can be done using the following commands:

sudo wget -O /usr/local/bin/up https://raw.githubusercontent.com/sharadchhetri/Shell_scripts/master/up/up.sh
sudo chmod +x /usr/local/bin/up

Once the up script is installed, you can use it as follows:

$ pwd
/home/user/Desktop/projects/code/scripts
$ up 2
$ pwd
/home/user/Desktop

In the above example, the user was in the directory /home/user/Desktop/projects/code/scripts. The up 2 command was used to move up two levels in the directory hierarchy, and as a result, the user ended up in the directory /home/user/Desktop.

You can also use the up command without specifying a number to move up one level in the directory hierarchy.

$ pwd
/home/user/Desktop/projects/code/scripts
$ up
$ pwd
/home/user/Desktop/projects/code

Conclusion

The up command is a simple yet powerful command that can save time and effort when navigating multiple levels of directories in Linux. It is easy to use and can be customized to meet your specific needs by modifying the up script.
