chmod 710
chmod 710 is rwx--x---.
What 710 grants
| Who | Digit | Permissions | Adds up as |
|---|---|---|---|
| Owner | 7 | read, write, execute | 4 + 2 + 1 = 7 |
| Group | 1 | execute | 1 = 1 |
| Others | 0 | no access | 0 |
When 710 is the right answer
Owner has full access; the group may traverse the directory but not list it. This lets a group reach a known path inside without being able to discover what else is there.
The command
chmod 710 filename
chmod -R 710 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 710 mean?
It sets owner to read, write, execute, group to execute, others to no access. In symbolic notation that is rwx--x---.
How do I apply 710?
Run chmod 710 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 710 safe?
It grants no write access outside the owner, so it is a reasonable setting as long as the owner is the account you intend.
What is 710 in symbolic notation?
rwx--x---. Written as ls -l shows it, with a leading file-type character, an ordinary file would appear as -rwx--x--- and a directory as drwx--x---.
