这是个片段上来
黏贴上来没有#！/bin/bash   
那个是我刚才打的

Shell_HAT

试试这样能否把cut省掉

1. wc -l < $PATH/release.txt

复制代码

big_turnip

就是因为我自己也觉的搓才上来求改进的
目的就是 读取release.txt
然后根据有几个IP列出例如
1:192.168.1.2
2:192.168.1.3
。。。。。。
然后输入数字选择IP
接着在列出IP后面的文件夹例如
1:/home/www
2:/home/iii
选择文件夹
release.txt里面的行数不固定

1. cat release.txt
   
2. 192.168.1.2 /home/www/ /home/iii
   
3. 192.168.1.3 /var/log /var/log/aaa
   
4. 192.168.1.100 /home/faa /home/tttt /home/ccc
   
5. 193.168.1.200 /home/www/yyyy /home/www/bbbb
