[Linux] bulk deletion job

When accidentally cast a giant multi-tasking, or delivery of resources is unreasonable, I want to kill the bulk of these tasks.

kill method is not to say, I use qdel way.
With such a single command:

 qstat |sed '1,2d' |awk -F' ' '{print $1}' |sed ':x;N;s/\n/ /;b x'|cat

And then qdeldelete it. Here it is a two-step, and with sedthe replacement line breaks with spaces look very complex, unfriendly.

In fact, it can be directly used xargsto simplify:

qstat |sed '1,2d' |awk -F' ' '{print $1}' | xargs qdel

May also be selectively deleted by the user or the operating state, such as a task only deleted without deleting the task wait state operation.

qstat -u USERNAME | grep "qw" | cut -d" " -f1 | xargs qdel

Also, delete tasks running:

qstat -u USERNAME | grep "r" | cut -d" " -f1 | xargs qdel
