用sed和awk填写路径

亞利艾爾

我承认我有病，在钻牛角尖。我知道我在做蠢事，所以不要问我做什么，我现在睡不着，就是这样……


1.

1. secludedsage@secludedsage-laptop:/home/secludedsage$ echo "sds" > 1.txt
   
2. secludedsage@secludedsage-laptop:/home/secludedsage$ cat 1.txt
   
3. sds
   
4. secludedsage@secludedsage-laptop:/home/secludedsage$ sed "s/d/\/home\/secludedsage/g" < 1.txt
   
5. s/home/secludedsages
   
6. secludedsage@secludedsage-laptop:/home/secludedsage$ sed "s/d/${PWD}/g" 1.txt
   
7. sed: -e expression #1, char 6: unknown option to `s'
   
8. secludedsage@secludedsage-laptop:/home/secludedsage$ echo $PWD
   
9. /home/secludedsage
   
10. secludedsage@secludedsage-laptop:/home/secludedsage$ sed "s/d/${PWD//\//\\\/}/g" 1.txt
    
11. sed: -e expression #1, char 8: unknown option to `s'
    
12. secludedsage@secludedsage-laptop:/home/secludedsage$ echo ${PWD//\//\\\/}
    
13. \/home\/secludedsage

复制代码

完全一样就是换不了……

另外就是awk的一个小问题：

1. secludedsage@secludedsage-laptop:/home/secludedsage$ mkdir s\\\\d
   
2. secludedsage@secludedsage-laptop:/home/secludedsage$ cd s\\\\d
   
3. secludedsage@secludedsage-laptop:/home/secludedsage/s\\d$ echo "1" > 1.txt
   
4. secludedsage@secludedsage-laptop:/home/secludedsage/s\\d$ awk -v PWD=$PWD '{print PWD}' 1.txt
   
5. /home/secludedsage/s\d
   
6. secludedsage@secludedsage-laptop:/home/secludedsage/s\\d$ echo $PWD
   
7. /home/secludedsage/s\\d

复制代码

　　显然两个不一样。一个是s\d一个是s\\d。
　　后面的我能想到的办法就是 PWD=${PWD//\\/\\\\}。但是太长了，不知道有没有好点的办法。前面的sed还真不知道为什么。



依然谢谢大家的回答。

echo sds | sed -e "s#d#$PWD#"
上面行不行?

另外,你似乎问错地方了,linuxsir有专门讨论脚本的地方,貌似
比这里更加合适啊.

sed "s@d@${PWD}@g" 1.txt
这样就可以了.

我当shell只是写shell，没有想到sed / awk编辑器也算……

问题有点欠抽。我之所以不换是因为PWD里也可能有#或者@……
