If I run this script in xterm, and I maximize (not resize) the window,
I'll get (nearly always) a very strange error... something like
./test: line 17: wait_for: No record of process 22659
but if I use 'read' without timing or with a very long time ( -t10 ) the
error does not raise.
-------
#!/bin/bash
trap trapfunc SIGWINCH
trapfunc () {
for i in {1..1000}; do
tput cup 0 0
echo OK
done
}
clear
echo maximize your window
while true; do
read -sn1 -t1
done
------
- read + SIGWINCH - strange error,
