centos 5.5 系统
/usr/bin/which: no expect in (/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)这是which出来的

安装expect包。。。

如果是64位选这个

    ftp://ftp.muug.mb.ca/mirror/cent ... .0-8.el5.x86_64.rpm

32位选这个
  
   ftp://ftp.muug.mb.ca/mirror/cent ... 43.0-8.el5.i386.rpm

装好了再跑一遍脚本就ok了

原来是没装expect  现在安装了。执行脚本提示-bash: spawn: command not found
couldn't read file "Escape character is '^]'.": no such file or directory
-bash: send: command not found
couldn't read file "ok": no such file or directory
-bash: send: command not found

    expect 1.sh

或者
   
   ./1.sh

来运行

话说。。。你知道 . 1.sh是在做什么呢。。。

    用 . 或者 source 运行脚本 会改变当前session的状态和环境变量， 不推荐～～～ 建议随手放一本shell脚本的参考书翻翻。

    [root@localhost shdir]# expect 1.sh
spawn /usr/bin/telnet 127.0.0.1 11211
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
flush_all[root@localhost shdir]#
现在这样 是正常的吗？

    正常。。。虽然我不晓得你的flush_all 是在做什么。。。

    而且也没有你所说的 "ok" 输出
