Understanding File Permissions (chmod, chown)
Learn about Linux file permissions, how they protect your data, and how to change them using 'chmod' and 'chown'.
What are File Permissions?
Welcome! In Linux, file permissions are security settings that control who can access and modify files and directories. They are crucial for protecting your data and ensuring system stability.
Think of them as digital bouncers for your files, deciding who gets in and what they can do once inside.
Read, Write, Execute (rwx)
There are three basic types of permissions:
- Read (r): Allows viewing the content of a file or listing the contents of a directory.
- Write (w): Allows modifying or deleting a file, or creating/deleting files within a directory.
- Execute (x): Allows running a file (if it's a script or program) or entering a directory.
