Subject: Trap bug?
Date: Fri, 09 Jan 1998 12:11:19 +0100 [thread overview]
Message-ID: <34B605D7.28EA4ABF@rrz.uni-hamburg.de> (raw)
This doesn't work correctly in 3.1.2:
function f
{
( trap 'print "INT f"; return 0' INT
while true; do :; done
)
print "Leaving f"
}
f
print "Leaving script"
Hitting Ctrl-C during the loop in f causes an immediate exit from the
_script_, not just a return from the function, as it should (IMHO).
If the trap command is outside the parentheses, it works:
function f
{ trap 'print "INT f"; return 0' INT
(
while true; do :; done
)
print "Leaving f"
}
But then the traps won't be automatically restored before leaving the
function, which is what I intended.
