XScreenSaver是在X-windows下一个标准的屏幕保护和锁定软件，具有高可配置性，内含超过100个显示模式。但是当我们在X-windows下运行游戏时，不想让XScreenSaver老是跳出来干扰，于是写了这个shell脚本。
它可以在运行一个特定的命令时暂时使xscreensaver失去功能，即在此期间用kill命令杀死xscreensaver的进程，直到相关命令停止运行。
该shell脚本(run-without-xscreensaver.sh)的代码如下：
#!/bin/sh

# Written by Michal Kosmulski <mkosmul _at_ users _dot_ sourceforge _dot_ net>
# This script is hereby put in the public domain.
#
# Run the program specified on the command line, disabling xscreensaver for the
# time that program is running (useful for games)
if [ $# -lt 1 ]; then
echo "Usage: $0 command [command-parameters]"
exit
fi
( while true; do xscreensaver-command -deactivate &>/dev/null; sleep 30; done ) &
pid="$!"
eval "$@"
kill "$pid" |
