I’ve been encountering a problem while trying to simulate “Ctrl + C” within a bash script. Basically, I am trying to simulate keystrokes after another command has been run. While I seem to have no problem terminating the script all together, I am only trying to interrupt it without actually killing it off or closing it, or if possible continue on with the rest of the script.
This is the trouble line here:
netstat -a -c & sleep 60 && kill SIGHUP 26777
I just want to scan for a minute, and interupt without closing/terminating. I have tried every combination of commands I can think of. Some of the solutions I have seen seem incredibly complicated and have only resulted in error for me. Is there an easier way to go about this? -Thanks in advance
How about this:
[user1@centos6 ~]$ netstat -a -c > /tmp/tmp.netstat-out & (nsPID=$! ; sleep 10 ; kill -STOP $nsPID)  25658 [user1@centos6 ~]$ + Stopped netstat -a -c > /tmp/tmp.netstat-out [user1@centos6 ~]$ ps -p 25658 PID TTY TIME CMD 25658 pts/1 00:00:00 netstat [user1@centos6 ~]$ jobs + Stopped netstat -a -c > /tmp/tmp.netstat-out [user1@centos6 ~]$ kill -CONT %1 [user1@centos6 ~]$ jobs + Running netstat -a -c > /tmp/tmp.netstat-out & [user1@centos6 ~]$
I stop the process with the SIGSTOP signal after 10 seconds (I’m impatient ;-)) and I can restart it any time I want with the SIGCONT signal (
