Bash Shell Scripting- String Operations on Paths | Useful for Real-time

The video tutorial explains three command line utilities: real path, base name, and directory name. The real path command converts file names to absolute paths without validating them. The base name command strips directory information and suffixes from file names. The directory name command removes suffixes starting from the last slash in a path, returning the directory name. These commands are useful for file path operations in scripting.
