# Setting Folder Permissions
|
|
|
|
## Symbolic Notation
|
|
|
|
'''bash
|
|
chmod u+rwx foldername # Give owner read, write, execute
|
|
chmod g+rx foldername # Give group read and execute
|
|
chmod o-rwx foldername # Remove all permissions for others
|
|
chmod -R u+rw foldername # Recursively give read/write to owner
|
|
'''
|
|
|
|
## Numeric Notation
|
|
|
|
'''bash
|
|
chmod 755 foldername # rwxr-xr-x (owner: all, group: read+execute, others: read+execute)
|
|
chmod 700 foldername # rwx------ (owner: all, no permissions for group or others)
|
|
chmod 777 foldername # rwxrwxrwx (all permissions for everyone - use cautiously)
|
|
'''
|
|
|
|
The -R flag makes it recursive within every subfolder beneath the folder referenced.
|
|
|
|
Common permission numbers:
|
|
|
|
755: Owner can do anything, others can read and execute
|
|
644: Owner can read/write, others can read
|
|
700: Only owner has access
|
|
777: Everyone has full access (generally avoid this)
|
|
|
|
## Setting Permissions to a Specific User
|
|
|
|
Use chown to set permissions to a specific user. (You'll almost always need to run with sudo)
|
|
|
|
'''bash
|
|
# Change owner of a file/folder
|
|
chown username foldername
|
|
|
|
# Change both owner and group
|
|
chown username:groupname foldername
|
|
|
|
# Recursively change ownership (include all files and subfolders)
|
|
chown -R username foldername
|
|
|
|
# Change owner and group recursively
|
|
chown -R username:groupname foldername
|
|
