Need help with sed command

I'm trying to delete everything after (and including) a particular phrase. The phrase that needs to be removed is anything with the letters "KV." For example:


would become:

I'm using the following, but i'm not having much luck. Any help would be greatly appreciated.

sed s/*KV*//g < file_1.txt > file_2.txt

Assuming that XXXXKV is always preceded with a space this should work:

sed 's/ [^ ]*KV.*//' input-file >output-file

From your original post you want the 230 from 230KV to be removed too. If not, then the solution by bartus11 will work. My solution drops the leading prefix of KV too.

thanks for the help. I actually tried your command, but i found that the numbers still remained. For example, the first line returned ATHENIA 230. I was looking for just ATHENIA.

However, I was able to modify your code to give me my desired output:
sed 's/[0-9]*KV.*//' < file_1.txt > file2.txt

However, is there a way to remove decimal values? My command only removes integers

Nevermind... I was able to figure it out with
sed 's/[0.0-9.0]*KV.*//' < file_1.txt > file2.txt

Thanks for pointing me into the right direction!

Change [0-9] to [0-9.] which will include the decimal point (dot) as a legit character in the pattern.

The command I posted initially will also handle decimal values; actually anything that prefixed the KV. That might match more than you want too.
