how can I recursively set pemission to all sub directories of a directory specified?

Question

with this command

sudo chmod 777 /var/www/

I get 777 on www but not under www/subdir1/subdir2 how can I set all subdirectories recursively to 777 with one command?

Answer 1

Use the -R flag.

so the command would be sudo chmod -R 777 /var/www/.

This is, however a bad idea and you should normally do it one at a time.
