Start an X app remotely
Launch a gui app remotely. In this example smplayer is installed on the remote machine, and movie.avi is in the remote user's home dir. Note that stdout/stderr is still local, so you'll have feedback locally, add '&>/dev/null' to suppress. This is surprisingly not well known (compared to running an X app locally via ssh -X). (NB. if your distro requires ~/.Xauthority file present, then try -fX if you have problems) Resubmitted (and trimmed, thanks sitaram) due to ridiculous voting on previous submission. Fingers crossed, it gets a better rating this time.

Hiding and Show files on Mac OS X
These commands will mark a file as hidden or visible to Mac OS X Finder. Notice the capitol V vs the lowercase v. This will also work for directories. setfile -a V; // This marks the file invisible setfile -a v; // This marks the file visible I have also found that adding the following aliases are helpful: alias hide='setfile -a V' alias show='setfile -a v'
