Commands

chmod 755 fileset it on one file or directory
chmod u=rwx,g=rx,o=rx filethe same thing in symbolic form
chmod -R 755 dir/recursively — careful: it applies to files and directories alike
ls -l filecheck the result: -rwxr-xr-x (a directory shows drwxr-xr-x)

On a directory, read lets you list it, write lets you create and delete entries, and execute lets you enter it and open what's inside. That's why directories usually get 755 or 750 while files get 644 or 640.
