求完整shell 语句，并执行

a.txt
222.83.128.0/17
222.84.0.0/16
222.85.0.0/17
222.85.128.0/17
222.86.0.0/15
222.88.0.0/15

b.txt
222.174.245.2

求循环输出成下列格式
ip route add 222.83.128.0/17 via 222.174.245.2
ip route add 222.84.0.0/16 via 222.174.245.2
ip route add 222.85.0.0/17 via 222.174.245.2
ip route add 222.85.128.0/17 via 222.174.245.2
ip route add 222.86.0.0/15 via 222.174.245.2
ip route add 222.88.0.0/15 via 222.174.245.2

justlooks大哥  和nomyself 大哥给的代码都可以输出，

sed -r '1{h;d};G;s/(.*)\n(.*)/ip route add \1 via \2 /;' <(cat b.txt a.txt)

cat a.txt | xargs -n 1 -i{} echo ip route add {} via `cat b.txt`

怎样设计成脚本执行呀？不用把输出变成文件
我自己的办法是先输出成文件

sed -r '1{h;d};G;s/(.*)\n(.*)/ip route add \1 via \2 /;' <(cat b a) >test
sh test

有没更简单的方法？写成shell怎样写

kwokcn

1. 
   
2. sed -r '1{h;d};G;s/(.*)\n(.*)/ip route add \1 via \2 /;' <(cat b a) | while read line; do $line; done
   

复制代码

1. 
   
2. sed -r '1{h;d};G;s/(.*)\n(.*)/ip route add \1 via \2 /;' <(cat b a) | sh -

用什么解释器呢？

写成文件mvvvv
sed -r '1{h;d};G;s/(.*)\n(.*)/ip route add \1 via \2 /;' <(cat b a) | sh -


[root@sdfsf test]# vi mvvvv
[root@sdfsf test]# sh mvvvv
mvvvv: line 1: syntax error near unexpected token `('
mvvvv: line 1: `sed -r '1{h;d};G;s/(.*)\n(.*)/ip route add \1 via \2 /;' <(cat b a) | sh -'

kwokcn

换成cat b a | sed ... | sh -
或者sed ... <<< cat b a | sh -

好像是转义输出的问题
是这样吗
我存储了也不行

你自己存储成shell 执行下看看

怎麼 s 貼不上的?再貼，  sorry, 班竹

gawk 'FILENAME == "j.txt"{x=NR;s[NR]=$0}END{for(i=1;i<=x;i++){
  print "ip route add", s, "via", $0}}' j.txt k.txt

------我看不到 s 和 加在一起，只見到一個 s, 編輯就見到，怪,-----

gawk 'FILENAME == "j.txt"{x=NR;s[NR]=$0}END{for(t=9;t<=x;t++){
    print "ip route add", s[t], "via", $0}}' j.txt k.txt
