chmod 764 — what rwxrw-r-- means

When to use 764

A shared data file the owner and group both edit, while everyone else may view but not change it. Note the owner also gets execute here — drop to 664 if it isn't meant to be run.

Set it with chmod

Apply this permission to a file:

chmod 764 filename

Or apply it recursively to a directory and everything inside it:

chmod -R 764 directory/

Other common permissions

• chmod 777 rwxrwxrwx
• chmod 755 rwxr-xr-x
• chmod 644 rw-r--r--
• chmod 700 rwx------
• chmod 600 rw-------
• chmod 640 rw-r-----
