When 776 is the right answer

Owner and group full, others read and write but not execute. On a directory this is a strange half-measure: others can create and delete entries but cannot traverse into subdirectories.

The command

chmod 776 filename
chmod -R 776 directory/

Because the owner has the execute bit, this works on a directory as well as a file — on a directory, execute is what grants the right to enter it and reach the entries inside.

Frequently asked questions

What does chmod 776 mean?

chmod 776 sets owner to read, write, execute, group to read, write, execute, others to read, write. In symbolic notation that is rwxrwxrw-.

How do I apply 776?

Run chmod 776 filename. Add -R to apply it to a directory and everything inside, though be careful: a recursive numeric chmod marks every file the same way, which is rarely correct for a mixed tree of files and directories.

Is 776 safe?

chmod 776 is world-writable, so any account on the system can modify the contents. That is only appropriate for a shared scratch area, and even then the sticky bit should normally be set as well. For anything else, grant access through a group instead.

What is 776 in symbolic notation?

rwxrwxrw-. Written as ls -l shows it, with a leading file-type character, an ordinary file would appear as -rwxrwxrw- and a directory as drwxrwxrw-.
