[Help-bash] Difference between INT and TERM?

[Peng Yu]

Hi,

I have the following scripts.
==> main.sh <==
#!/usr/bin/env bash

set -v
./script.sh &
pid=$!
sleep 1
kill -s INT "$pid"


==> script.sh <==
#!/usr/bin/env bash

trap "echo $0:$$:EXIT" EXIT
sleep 10
exit -1

I will see something like "./script.sh:15449:EXIT" printed to the
screen in 10 sec.

But if I change INT in main.sh to TERM, I will see the message printed
right after kill.

I understand that the default for INT and TERM are both exit. Why they
are different in the above test cases?
