Linux nohup process terminated when using tailf

Here is my script (run.sh):

rm -f nohup.out
nohup myproc &
tailf nohup.out

If I run the script (sh run.sh) then press Control-C, myproc will be terminated, but if I comment the tailf nohup.out part, myproc will run on background as expected. Am I doing anything wrong?

The problem is not SIGHUP (which nohup would catch) but SIGINT which you send by pressing Control-C. This is propagated to your process.

See this blog post for more details.

From what I read from that post you could change your code to something like this:

setsid myproc 1> output.log 2>&1  &
tail -f output.log

If you dont want to use your own output redirection, you can still use nohup:

setsid nohup ping -c 30 localhost &
tail -f nohup.out

Hope this helps!
