$rootcrontab
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/

$test.sh
ps -e>; psf
if grep '<defunct>;' psf >;/dev/null 2>;&1
then
echo "socks5 is dead!"
stopsocks -p 1888 -KILL
echo "start socks5!"
socks5 -b 1888 -t -s 2>; /var/log/socks5
else
if grep 'socks' psf >;/dev/null 2>;&1
then
echo "socks5 is running"
else
echo "start socks5"
socks5 -b 1888 -t -s 2>; /var/log/socks5
fi
echo "socks5 is ok!"
fi
