杀掉一个进程
#!/bin/bash
pid=`(ps -ef | grep /home/jiao/8.3.1.4b23/etc/gs_express.cnf | grep -v "grep") | awk '{print $2}'`
kill -9 $pid
 
------------------------------------------------------------------
ps -ef|grep 条件|grep -v grep |awk '{print $2}'|xargs -n1 kill -9
------------------------------------------------------------------
 
批量杀掉进程
#!/bin/sh
keys=`(ps -ef |grep "rsync" |grep -v "grep") | awk '{print $2}'`
for key in ${keys[*]}
do
       kill -9 $key
done
------------------------------------------------------------------
 
转一个脚本stop.sh
 
#!/bin/bash
#stop.sh
if [ ! $1 ]; then
echo "Usage: $0 <name> [l]"
echo " l just list"
else
param=$1
fi
if [ "$2" = "l" -o "$2" = "L" ]; then
ps aux | grep $1 | grep -v "grep"
exit
fi
# process every prog like $1
for pid in `ps aux | grep $param | grep -v "grep" | awk '{print $2}'` ; do
ok=true
pid_name=` ps aux | grep $pid | sed -n '1P' | awk '{print $11}'`
#sed -n '1P' 相当于 grep -v grep
# if have such pid,(becaus some time when the first be killed , the forked pid will be killed all the same, for example mozilla.)
if [ $pid_name ]; then
echo -n "name: $pid_name pid: $pid Kill? [Y/n/q]:"
read confirm
#want quit...
if [ "$confirm" = "q" -o "$confirm" = "Q" ]; then
echo " Quit..."
exit
fi
#echo "$confirm"

#want to kill..
if [ "$confirm" = "" ]; then
echo -n " killing...default"
kill -9 $pid
echo "ok."
else
if [ $confirm = 'n' -o $confirm = 'N' ]; then
echo -n " Canceled..."
echo $'a'
continue
else
if [ "$confirm" = "y" -o "$confirm" = "Y" ]; then
echo -n " killing...(confirmed)!"
kill -9 $pid
echo "ok."
fi
fi
fi
# no such pid
else
echo "no such pid $pid";
continue
fi
done
# kill over. 
if [ $ok ]; then
echo "All prog like "$1" were prcessed by you!"
else
echo "Sorry, No such prog like "$1""
fi

使用方法：杀掉进程
sh stop.sh gbased
name: /usr/bin/mozilla pid: 26608 Kill? [Y/n/q]
默认为Y,输入时大小定皆可,
直接回车为杀,输Y或y也杀.
输n或N为不杀,并继续下一个.
输q或Q为退出脚本.
----------------------------
查看进程
sh stop.sh gbased L

翻译该脚本
#!/bin/bash
#####-----#！表示用之后跟的shell来运行该脚本
#stop.sh
 
if [ ! $1 ]; then
#####---------------------------首先判断“要杀掉的进程”是否存在，$1代表第一个用户变量，即你要输入的进程名字。
echo "Usage: $0 <name> [l]"
#####---------------------------若不存在，打印当前命令的帮助。Usage无意义，$0代表当前程序，<name>
<>代表其内的参数是必须要存在的，[]代表其内的参数是可选的。即打印出来的帮助信息是，执行stop.sh脚本时，必须要跟上想杀掉的进程名字，用l仅列出所有该进程的程序名。
echo " l just list"
else
param=$1
fi
if [ "$2" = "l" -o "$2" = "L" ]; then
#####-----------------------------------实现l和L不区分大小写。-o是“或者”
ps aux | grep $1 | grep -v "grep"
#####-----------------------------------当输入l或者L时，输出所有进程名为$1的程序
exit
fi
# process every prog like $1
for pid in `ps aux | grep $param | grep -v "grep" | awk '{print $2}'` ; do
ok=true
pid_name=` ps aux | grep $pid | sed -n '1P' | awk '{print $11}'`
#####-----------------------------------------------------------sed -n '1P' 相当于 grep -v grep
#####-----------------------------------------------------------将进程名字对应的程序名输出
# if have such pid,(becaus some time when the first be killed , the forked pid will be killed all the same, for example mozilla.)
if [ $pid_name ]; then
#####-----------------------------------------------当pid_name存在，则印出下句内容
echo -n "name: $pid_name pid: $pid Kill? [Y/n/q]:"
read confirm
#####-----------------读取confirm变量的内容，即键盘上敲入的Y/n/q
#want quit...
if [ "$confirm" = "q" -o "$confirm" = "Q" ]; then
echo " Quit..."
exit
fi
#echo "$confirm"

#want to kill..
if [ "$confirm" = "" ]; then
echo -n " killing...default"
kill -9 $pid
echo "ok."
else
if [ $confirm = 'n' -o $confirm = 'N' ]; then
echo -n " Canceled..."
echo $'a'
continue
else
if [ "$confirm" = "y" -o "$confirm" = "Y" ]; then
echo -n " killing...(confirmed)!"
kill -9 $pid
echo "ok."
fi
fi
fi
# no such pid
else
echo "no such pid $pid";
continue
fi
done
 
# kill over. 
if [ $ok ]; then
echo "All prog like "$1" were prcessed by you!"
else
echo "Sorry, No such prog like "$1""
fi
