Implementing Directory Management using Shell Script

Directory management constitutes the functions dealing with organization and maintenance of various directories. Directories usually contain files of any type, but this may vary between file systems. The content of a directory does not affect the directory object itself.

Some of the directory functions are:

• Navigation
• Absolute/ Relative Pathnames
• Listing Directories
• Creating Directories
• Modifying Directories

You can write your script in an editor like pico etc. Execute your files as mentioned below in the output screenshot. The following shell script implements these functions of directory management, using commands available in Linux.
