请教如何进行格式修改?

shizier

我想将
Tue Oct 23 14:51:00 CST 2007
<caps> 19.5000 </caps>
合并为一行显示,
Tue Oct 23 14:51:00 CST 2007  <caps> 19.5000 </caps>
该如何编辑?谢谢

davistar

1. 
   
2. sed '/Tue Oct 23 14:51:00 CST 2007/{N;s/\n//}'
   

复制代码

应该有很多行,时间不相同,但格式一样,该怎么做?

davistar

1. 
   
2. sed -r '/.*CST [0-9]{4}/{N;s/\n//}'
   

复制代码

还不行的话，就给出点数据来

springwind426

写一个麻烦的
test.sh

1. 
   
2. #!/bin/bash
   
3. read old
   
4. while read new
   
5. do
   
6.    echo -n $old;
   
7.    if [ "${new:0:4}" == "<cap" ];then
   
8.      echo $new;
   
9.      read old;
   
10.    else
    
11.      echo;
    
12.      old=$new;
    
13.    fi
    
14. done
    
15. echo $old
    

复制代码

chmod +x test.sh
test.sh file

springwind426

再用awk写一个

1. 
   
2. awk '{printf (/^<cap/||NR==1)?$0:"\n"$0}END{print ""}'
   

复制代码

这样做以后，凡是以<cap开头的，都移动到上一行去打印
