Hi all,

I'm experiencing this problem usign "onintr" command: if you run a csh script from a sh prompt, the onintr command has no effect.

Here is the csh script (working fine if run from a csh prompt):

#!/bin/csh
set exitreq = 0
onintr exit_request

while ( 1 == 1 )
if ( $exitreq == 1 ) then
printf "\n\nExit request (via signal 2), exiting..."
exit 2
endif

end

exit_request:

printf "\n\nWARNING: **** signal INTERRUPT (2) received ****...\n"
set exitreq = 1
continue


And here is the problem:

ibdvsmt1{ubmcopyprod} sh
$ mytest.csh &
8650
$ kill -2 8650
$ ps -ef | grep mytest.csh | grep -v grep
eodprod 8650 8475 2 11:16:51 pts/115 0:11 /bin/csh ./mytest.csh
$

Truss output says the signal is received but ignored:

sigprocmask(0, 0x00000000, 0xFFBED3D8) = 0
Received signal #2, SIGINT [ignored]
siginfo: SIGINT pid=5919 uid=5129
sigprocmask(SIG_BLOCK, 0xFFBED3D8, 0xFFBED3C8) = 0

Did anyone have to fight with this ?

Thanks in advance.
Ciao,
Marco

Try on Solaris:

ible-mx2% sh -c "mytest.csh" &
[2] 21658
ible-mx2% ps -ef | grep mytest
mxtest 21659 21658 2 15:41:04 pts/21 0:02 /bin/csh -f ./mytest.csh
mxtest 21678 20844 0 15:41:08 pts/21 0:00 grep mytest
mxtest 21658 20844 0 15:41:04 pts/21 0:00 sh -c mytest.csh
ible-mx2% kill -2 21658
ible-mx2% <no effect>


Try on AIX:


sumuser@usi_tes /home/sumuser # sh -c "mytest.csh" &
[1] 256306
sumuser@usi_tes /home/sumuser # kill -2 256306
sumuser@usi_tes /home/sumuser #
