chmod 714 — the rwx--xr-- permission
714 is rwx--xr--. The owner gets rwx, and everyone else gets r.
Who can do what
Three rows for owner, group and others; three columns for read, write and execute. On a folder that last one means the right to go inside.
| Read | Write | Execute | |
|---|---|---|---|
| Owner7 | ✓ | ✓ | ✓ |
| Group1 | · | · | ✓ |
| Others4 | ✓ | · | · |
On a folder the execute bit means going inside. With read but no execute you can list the names yet open nothing in it.

One digit away
How to read this
- Read is 4, write 2, execute 1; add them for one digit. 7 is 4+2+1, 5 is 4+1.
- The digits are owner, group, others, left to right.
- umask is what gets taken away: from 777 for directories, from 666 for files.
- Special bits (setuid 4000, setgid 2000, sticky 1000) add a fourth digit in front — /tmp is 1777.
