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： #!/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 [ $? -ne 0 ]; then break fi /usr/bin/printf . /bin/sleep 1 let i=$i+1 done fi /bin/echo "" 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 (责任编辑：IT) |
