Difference between absolute path and relative path ?

  • Absolute Path: An absolute path specifies the complete location of a file or directory from the root directory (/ in Linux or C:\ in Windows).
  • Relative Path: A relative path specifies the location of a file or directory relative to the current working directory.

Command to find empty files in a given directory?

find /path/to/directory -type f -empty

Delete empty file
find . -type f -empty -delete

I want to delete log which is 10 days old in Linux ?

find /path/to/logs -type f -mtime +10 -exec rm -f {} \;

Explain the difference between chmod, chown, and chgrp.

  • chmod: Modifies the file or directory permissions (read, write, and execute).
  • chown: Changes the ownership of a file or directory. It assigns a new user and/or group as the owner.
  • chgrp: Changes the group ownership of a file or directory.
