When sourcing this script (version 1), it will print y after receiving
an interrupt, but not in the 2 different versions (2 and 3).
# version 1
echo x
sleep 99
echo y
# version 2
echo x; sleep 99
echo y
# version 3
echo x
sleep 99; echo y
Is this a bug or expected behaviour??
Thanks for your
Hi
In a small bash script we have a trap to cleanup some files when exiting. You
run the script by ssh to the machine in question and execute the script. If
your ssh session dies the trap should trigger and clean up the files as the
script exit but this doesn't happen.

I tried to use read -t 0 to check if there is any data on the STDIN or not.
The man page said:
If timeout is 0, read returns success if input is available on the specified
file descriptor, failure otherwise.
Maybe I made a mistake but I tested and I got variable results:

There is a race condition, you cannot know if echo will run before read.
I see, and it's logical. But this stills confuses me.
