🔐 Bash File Permissions

Bash lets you control who can read, write, or execute files with chmod, chown, and ls -l to check permissions.

📖 Example: Change and View Permissions

# View permissions
ls -l myfile.txt

# Add execute permission for the user (owner)
chmod u+x myfile.txt

# Remove write permission for group
chmod g-w myfile.txt

# Change owner to user "alex"
chown alex myfile.txt

💡 Tip: Use u, g, and o for user, group, others; +/- to add/remove permissions; r, w, x for read, write, execute.
