I have a task, to replace specific pattern in a string.
So far I tried commands like
sed -e 's/text_to_find/text_to_replace/g' file
but I don't why it changed all string, not just a part which I wanted to change.
what I want to do is in every string that contains word
china to add this
To make it very clear, what I am looking for, there is file I am using:
987173,businesswirechina.com 988254,chinacfa.com 988808,1012china.com 989146,chinawise.ru 989561,chinaretailnews.com 989817,mobileinchina.cn 990894,cmt-china.com.cn 990965,chinajoy.net 992753,octaviachina.com 993238,chinadftzalex.com 993447,china-kena.com
And this is I would like to see in a new file
987173,Tomas_proxy.lt/businesswirechina.com 988254,Tomas_proxy.lt/chinacfa.com 988808,Tomas_proxy.lt/1012china.com 989146,Tomas_proxy.lt/chinawise.ru 989561,Tomas_proxy.lt/chinaretailnews.com 989817,Tomas_proxy.lt/mobileinchina.cn 990894,Tomas_proxy.lt/cmt-china.com.cn 990965,Tomas_proxy.lt/chinajoy.net 992753,Tomas_proxy.lt/octaviachina.com 993238,Tomas_proxy.lt/chinadftzalex.com 993447,Tomas_proxy.lt/china-kena.com
P.s. This is just example file, In real file I am using, not every line has word
china ,there is 100000 strings and lets say about 500 has
