~/bin: scroff

I play movies using mplayer, and it's somewhat annoying when my screen goes to sleep after half an hour. scroff runs a command with gnome-screensaver or DPMS disabled (depending on which is available).

$ scroff mplayer big_buck_bunny_720p_stereo.ogg

And the script:

#!/bin/sh

if [[ -x `which gnome-screensaver-command 2>/dev/null` ]]
then
    gnome-screensaver-command --inhibit &
    pid=$!
    "$@"
    kill $pid
elif [[ -x `which xset` ]] \
    && [[ `xset q | grep "DPMS is Enabled"` ]]
then
    xset -dpms
    "$@"
    xset +dpms
else
    "$@"
fi

Since I use mplayer all the time I've saved the following as ~/bin/mplayer:

  #!/bin/sh

  scroff /usr/bin/mplayer "$@"
