Absolute path and Relative path

What is a path?

A path is a unique location of a file or a folder in a file system of an OS. A path to a file is a combination of / and alpha-numeric characters.

What is an absolute path?

An absolute path is defined as specifying the location of a file or directory from the root directory(/). In other words, an absolute path is a complete path from the start of the actual filesystem from the / directory.

Some examples of the absolute path:
/home/imran/linux-practices/
/var/ftp/pub
/etc/samba.smb.conf
/boot/grub/grub.conf

If you see all these paths started from the / directory which is a root directory for every Linux/Unix machine.

What is the relative path?

The relative path is a path related to the present working directory(pwd). Suppose I am located in /home/imran and I want to change the directory to /home/imran/linux-practices. I can use the relative path concept to change the directory to Linux practices and also the devopsdir directory.

If you see all these paths did not start with / directory.

➔ Copying directories from one location to another.

➔ Moving files from one location to another.
