手工执行一个shell就可以,但加入crontab -e 后执行就报错.
系统sco openserver 5.0.4

shell如下:
backserver=`ps -ef|grep backupserver`
if [ "X$backserver" = "X" ]
then
echo "启动备份数据库!\n"

/usr/sybase/install/startserver -f /usr/sybase/install/RUN_backup &
sleep 3

backserver=`ps -ef|grep backupserver`

if [ "X$backserver" = "X" ]
then
echo "未能成功启动备份服务器!!!\n"
exit 1
fi
fi

echo "开始恢复数据库\n"

if [ $? -ne 0 ]
then
exit 1
fi
