写了一个脚本，用来查找打开了某个路径下文件的进程都是哪些，例子中，假设需要匹配的进程是打开了路径包含IDMDomain的文件。
我写的脚本如下：
for pid in `lsof 2>/dev/null |grep IDMDomain |awk '{print $2}' | uniq`
do
ps -ef |grep ${pid}
done
实例输出如下：

可以看到，结果还是比较乱，包含了grep命令本身的输出。
对于这个需求，还有其他更好的实现吗？
将ps -ef |grep ${pid}替换成ps -p ${pid} -o comm=
lsof 2>/dev/null |grep IDMDomain
这样写不行么？
