如何退出tail -f并恢复脚本

Question

I have a simple script, that sets up logging, runs tail -f on the log file and then, after I exit tail , performs some cleanup. Basically something like this

echo 'monitoring started'
tail -f /var/log/some.log
echo 'never gets here'

Problem is, exiting tail by Ctrl+C breaks the script execution too, so cleanup is not called. Is there a way to 'properly' exit tail and resume script call? I found a few solutions based on saving PID and killing it by timeout, but that's not what I want here, I may need the monitoring for a few minutes or few hours, so I'd like to have a manual switch.

You can do something like this

echo "monitoring started"
tail -f /var/log/some.log & #execute tail in background
read -sn 1 #wait for user input
kill %1 #kill the first background progress, i.e. tail
echo "Is reached"
