only try fc-cache reset on linux

[CarlQLange]

fc-cache doesn't exist on osx :)

I'm pretty sure if [[ -n -which fc-cache]] checks if fc-cache exists in $PATH, so this command shouldn't run if fc-cache is unavailable.

fyi it did actually try to run fc-cache on my machine, hence the need for this patch, as the script bombed out without it.

if [[-n `which fc-cache ]]

actually checks if the output of which fc-cache and tests if it's a null string or not. At least on my machine, if which can't find fc-cache, it says 'fc-cache not found', not an empty string. A better test is something like:

if command -v fc-cache 2>/dev/null; then fc-cache -f $font_dir; fi

Here's more info about why you should avoid which in this script

And here's a screenshot of the current if not working:

Allright, that makes sense. On Linux the output of which is empty if the command doesn't exist, I didn't realize this behavior isn't consistent across systems. I think that instead of testing the uname output we should fix the issue with using which so it works consistently across systems.

I agree with the if command... solution you posted, if you could update the PR I'll merge it.

[CarlQLange]

OK, updated. You might want to make sure it works the same way on your system. It works fine for me now. :)

Works like a charm, thanks a lot!
