主要目的是用于重启后台比较重要的进程，如果采用killall -9强制kill掉，可能会引起问题。比如数据库进程。代码如下：
复制代码 代码如下:
#!/bin/sh
if [ -z "$1" ]; then
/bin/echo "$0 <command line>"
exit 1
fi
param=''
list='2 3 4 5 6 7 8 9'
for i in $list; do
eval p='$'$i
if [ -z $p ]; then
break
fi
param="$param $p"
done
if [ -f /bin/awk ]; then
AWK=/bin/awk
else
AWK=/usr/bin/awk
fi
if [ -f /bin/grep ]; then
GREP=/bin/grep
else
GREP=/usr/bin/grep
fi
program=`/bin/echo $1 | $AWK -F '/' '{print $NF;}'`
count=`/bin/ps auxww | $GREP -w $program | $GREP -v grep | /usr/bin/wc -l`
if [ $count -gt 0 ]; then
i=0
/bin/echo "stopping $program ..."
while [ 1 -eq 1 ]; do
if [ $i -eq 0 ]; then
/usr/bin/killall $program
else
/usr/bin/killall $program >/dev/null 2>&1
fi
if [ $""
count=`/bin/ps auxww | $GREP -w $program | $GREP -v grep | $GREP -v $0 | /usr/bin/wc -l`
if [ $count -eq 0 ]; then
/bin/echo "starting $program ..."
exec $1 $param
else
/bin/ps auxww | $GREP -w $program | $GREP -v grep | $GREP -v $0
/bin/echo "already running $program count: $count, restart aborted!"
fi
