python的paramiko源码修改了一下，写了个操作命令的日志审计，但是记录的日志中也将backspace删除键记录成^H这个了，于是改了一下代码，用字符串的特性。
字符串具有列表的特性
>>> a="hello world" >>> a[:-1] ‘hello worl‘
转义符
转义字符 \(在行尾时) 续行符 \\ 反斜杠符号 \‘ 单引号 \" 双引号 \a 响铃 \b 退格(Backspace) \e 转义 \000 空 \n 换行 \v 纵向制表符 \t 横向制表符 \r 回车 \f 换页 \oyy 八进制数yy代表的字符，例如：\o12代表换行 \xyy 十进制数yy代表的字符，例如：\x0a代表换行 \other 其它的字符以普通格式输出
代码部分
if sys.stdin in r:
x = sys.stdin.read(1)
if x == ‘\b‘:
cmd=cmd[:-1]
else:
cmd+=x
#records.append(x)
if x == ‘\r‘:
#print "your input is:",cmd
log_line = "-login_user:%s\t|host_addr:%s\t|%s|HISTORY_CMD: %s \n" % (username,hostname,time.strftime("%Y_%m_%d %H:%M:%S"),cmd)
cmd = ‘‘
log_file.write(log_line)

shell 变量传入python脚本，修改后的源码脚本就不粘贴了。
root@python:~/baolei# cat remote.sh #!/bin/sh #created by liujianzuo list(){ #cd /home/liujianzuo/server/scripts echo "\033[33;1m########################################################\033[0m" awk ‘{printf "\033[35;1m%s:\t[%-4s]\t%20s\t%s\033[0m\n",NR,$2,$1,$NF}‘ remote_ip.log echo "\033[33;1m########################################################\033[0m\n" } wai_t(){ echo "\033[32;1m before choose items will be sleep a monent\033[0m\n" # for i in {1..3};do sleep 0.6 && echo -e "\033[35;1m..........................\033[0m";done #read -p "Please choose ip of top:" num while true do if [ -z $num ] && [ -z $username ];then read -p "Please choose ip of top:" num read -p "Please input your username:" username continue else break fi done IP=`awk -v ip=$num ‘NR == ip{printf "%s:\t[%10s]\t%-20s\t%s\n",NR,$2,$1,$NF}‘ remote_ip.log|awk ‘{print $NF}‘` } list wai_t python=`which python` echo $username $IP python demo.py $IP $username
还有几个bug要修改：
终端内切换ip，审计日志的ip要相应变化。
登陆服务器密码失败一次不退出。
