Execute command after process terminates in different shell

bashcommand lineshell

I am running a command that's processing some data in one shell window (let's say it has pid 200). Unfortunately I forgot to add the & to run it in the background.

I need to run some analysis script after pid 200 is finished. I thought I could just open up another shell window and do

wait 200; ./myanalysis.sh

But it complains to me

"-bash: wait: pid 200 is not a child of this shell"

With that in mind, is there a way I can execute my analysis script automatically after this process terminates?

You can't "wait" for non-child processes, and you have to manually check it periodically. See for example this stack overflow answer.

You could simply add the following command into System > Preferences > Startup Applications:

bash /full/path/to/your/script.sh

That should do the trick ;)

You can use bash job control:

#!/bin/bash

./server &
./client
kill %1

Be sure to put the #!/bin/bash at the beginning of the script so that bash is used to execute the script (I'm not sure if job control is supported in sh, please correct me if it does).
