- | + | \\ | |
+ | chmod 777 examply.py | ||
+ | ls -l | ||
+ | -rwxrwxrwx 1 pi pi 4452 Jul 25 18:01 example.py | ||
+ | \\ | ||
+ | \\ | ||
+ | We just did a CHMOD 777 on a file, so: | ||
+ | \\ | ||
+ | File has FULL permissions | ||
+ | -rwxrwxrwx is -111111111 or in octal 777 | ||
+ | \\ | ||
+ | \\ | ||
+ | Now we will revert the permissions: | ||
+ | \\ | ||
+ | chmod 644 example.py | ||
+ | \\ | ||
+ | \\ | ||
+ | Now we have used CHMOD 644, so: | ||
+ | \\ | ||
+ | ls -l | ||
+ | -rw-r--r-- 1 pi pi 4452 Jul 25 18:01 example.py | ||
+ | |||
+ | Now our file is back to its original permissions. | ||
