Killing the correct process

[Maarten Litmaath]

In article <22332 at adm.BRL.MIL>,
	marwood at ncs.dnd.ca (Gordon Marwood) wants to timeout ftp.

How about using the following general purpose script?  If that's out of the
question, the script might still give you a hint how to solve your problem.
----------8<----------8<----------8<----------8<----------8<----------
#!/bin/sh
# @(#)timeout 4.1 90/01/10 Maarten Litmaath

prog=`basename $0`
verbose=0

case $1 in
-v)
	verbose=1
	shift
esac

expr $# \< 2 \| 0"$1" : '.*[^0-9]' > /dev/null && {
	echo "Usage: $prog [-v] <timeout in seconds> <command>" >&2
	exit 2
}

timeout=$1
shift

exec 3>&1 4>&2 2> /dev/null

pid=`
	sh -c '
		(sleep '$timeout' > /dev/null & echo $!; exec >&-;
		wait; kill -9 $$) & exec "$@" >&3 3>&- 2>&4 4>&-
	' $prog "$@"
`

kill -9 $pid && exit 0
test $verbose = 1 && echo TIMEOUT >&4
exit 1
