Common Linux file and folder permissions | chmod chown octal home src


Here is a list of some common settings, numerical values and their meanings:
-rw------- (600) — Only the owner has read and write permissions.
-rw-r--r-- (644) — Only the owner has read and write permissions; the group and others have read only.
-rwx------ (700) — Only the owner has read, write, and execute permissions.
-rwxr-xr-x (755) — The owner has read, write, and execute permissions; the group and others have only read and execute.
-rwx--x--x (711) — The owner has read, write, and execute permissions; the group and others have only execute.
-rw-rw-rw- (666) — Everyone can read and write to the file. (Be careful with these permissions.)
-rwxrwxrwx (777) — Everyone can read, write, and execute. (Again, this permissions setting can be hazardous.)

Here are some common settings for directories:
drwx------ (700) — Only the user can read, write in this directory.
drwxr-xr-x (755) — Everyone can read the directory; users and groups have read and execute permissions.
