阐明

其实我之前文章中已经有说过这个的解决办法
expect结合scp主动输入密码的脚本提取linux主机的ip和其mac地址、scp结合expect运用【不用spawn发动scp】、while遍历目录获取一切文件称号【cat文件＞＞到同一目录】 -
但是今天，我在expect中运用scp的时分，我又忘了上面脚本中已经遇到过这个问题，所以一直报错，搞得我真是难过，良久才想起来之前遇到过的，但想起了没用啊，发现本次的需求和上一次的底子不相同，不能直接套现来用，所以我觉得有必要独自拿一个文章来说说这个问题！！！！
-
标题中你可能没能理解是啥意思，反正便是，当你在expect脚本中运用scp指令的时分，咱们知道scp 后边是需求跟文件名参数的，而咱们批次跑scp后边文件称号不可能相同，那么问题就来了，已然每台主机上的scp文件称号不能相同，那么咱们可能就需求用其他办法来动态获取这个scp称号【如下指令行】。
- 所以我想表达的便是，这个动态称号，在expect中是无法动态获取的，获取到的参数是你履行机的参数，而非expect登录的主机参数，所以就会造成参数获取失利。
- 如下履行代码，
ls /tmp/|grep 10.20.获取到的值只能是履行机的，而非登录主机，至于为什么获取到的只能是履行机的参数，我这不做阐明，牵扯到履行的子bash了，解说起来有点复杂。
expect "*]#" {send "scp `ls /tmp/|grep 10.20.` 10.20.101.6:/tmp/hegui\r"}
- 解决办法便是，把这个指令放在登录主机上，然后expect调用登录主机上的这个指令，简略来说便是把这行指令剥离开expect脚本。
- 我文章最初脚本中的办法是将scp脚本固定到履行机上，然后登录主机复制履行机上的这个脚本再调用履行，我这换一种办法，直接用echo动态的办法将这个脚本内容写入到登录机，然后再调用，相对来说更灵活一点?
需求&脚本代码
- 上面文章中脚本和本脚本的区别，这2种区别基本上也便是scp所遇到的一切场景了：
- 上面文章中脚本是将指令回来的结果重定向到一个文件名中，此时文件名是固定的【内容是变化的，但不影响】，scp的文件名也便是固定的 ，所以能够直接将scp代码写入sh脚本中，将sh脚本放到某个主机上，expect脚本复制sh脚本过来履行即可。
- ==本篇文章中的脚本是经过脚本获取到一个文件，该文件名不是固定的，所以上面办法不能用，必须想办法再本机上获取到跑脚本生成的文件名，再将该文件名放到scp后边【难就难在 expect脚本中不能用
$()这种办法来获取值，得想办法获取到文件名，然后界说到scp后边】==
- 我这的需求是：
- 1、经过rpm包装置2个指令
- 2、履行合规脚本
- 3、复制文件到履行机上汇总【首要是这个】
- 先解说下本文章的首要困难完成代码
上面文章中 思路是对的，将scp代码放到一个sh脚本中，本文章便是难在，如何生成这个scp的sh代码，scp 后边跟的是文件名，这个文件名到底咋动态获取并跟在scp后边！
# 主机上，下面代码就能定位到脚本生成的文件
[root@compute01 ~]# ls /tmp/ | grep 10.241
10.20.101.1_46c221be-6ab2-ef53-1589-fe16877914f4_chk.xml
[root@compute01 ~]#
# 手动履行的话就简略了 scp `ls /tmp/ | grep 10.241`10.20.101.6:/tmp/hegui' >/tmp/scp.sh
# 可是expect中不支持 ` ` 回来结果，所以ls /tmp/ | grep 10.241的值咋放到scp后边真的有点折磨人
# 脚本可能是不能放到其他地方复制过来的，因为文件名不固定，本机上不能用`` 动态获取也就完成不了。
# 我尝试了许多许多办法，最后发现下面代码是正解，也是最简略的！ 直接将代码写入文件 ，让`不履行就行了。
expect "*]#" {send "cd /tmp/\r"}
#下面grep条件要改
expect "*]#" {send " echo 'scp \`ls /tmp | grep 10.20.\` 10.20.101.6:/tmp/hegui' >/tmp/scp.sh \r"}
expect "*]#" {send "sh scp.sh\r"}
- 下面全体结构我一直再用，变化的仅仅send中的内容，所以我就不对代码做啥解说了，有看不懂的，留言或私信即可。

代码履行
- 履行前需求在履行机中创建一个
/tmp/hegui文件【上面界说的文件都放到这个文件夹中】
[root@controller01 ccx]# mkdir /tmp/hegui
- 然后就能够履行代码了 :
sh hegui.sh ip.list
[root@controller01 ccx]# sh hegui.sh ip1-6.txt
