Change permissions recursively?

99.99% of terminal commands aren't Sailfish-specific, but rather they apply to most Linux and Unix systems. So you'll have more luck searching for solutions on the internet with the keywords Linux / Unix / bash / sh rather than on Jolla sites.

Also, since you only want read and execute (although read should be enough, no?), use +rx. the basic rule is to not set all permissions to everybody if it's not necessary.

There is no need to set the execute bit on regular files, but you will need it on directories. Use an upper case X to only add the execute bit for group and others where it is already set for the owner: chmod -R a+rwX /home/nemo/Music

thanks raimue i think thats my answer a little more accurately than mine, whats the "a" btw?

'a' is for all of user, group, and others. You could also use 'u', 'g', or 'o' before the plus sign to only change the respective rows you saw in your initial screenshots.
