I am on a cluster equiped with IBM LSF job system.

I want to realize a feature, so that I can peek current output of every job I am running

So I write

for((i=2;i<=$(bjobs|grep RUN|wc -l)+1;i+=1)); do bpeek -f $(bjobs | awk '{print $1}'| head -n $i|tail -1);done

However, since bpeek enters into peeking mode, the loop is not gonna loop.

So I thought maybe I could kill bpeek at the end of each peak. However I found that PID of bpeek is not listed in ps -ef. So this seems not working.

Does anyone knows how to work around this?

bpeek will definitely be in ps. – 123 May 06 '16 at 09:07
@123 Hi. I tried it. At least `ps -ef|grep bpeek` only returns grep itself – user15964 May 06 '16 at 15:48
bpeek will exec() a process called nios. You can ps -ef | grep for that. – Michael Closson May 09 '16 at 20:46
@MichaelClosson Hi, MichaelClosson. I am curious how do you know that? – user15964 May 10 '16 at 10:57
You can use `strace`. You can also check the child processes of the shell that ran the bpeek. – Michael Closson May 10 '16 at 12:20
