Replace word pattern using sed

I have a file with the following structure:

prefix_postfix123456 some text1  other stuff
prefix_postfix88989898 some text2 other stuff

I want to replace all prefix* to prefix, and keep the rest of the file as is:

prefix some text1  other stuff
prefix some text2  other stuff

I have try this:

sed -i 's/prefix[\s]*/prefix/g' fileName

But this doesn't work.

Could you please show me how can I do that?

OutPut:

prefix some text1  other stuff
prefix some text2 other stuff

Assuming that your data is separated by spaces, then this should do what you want:

sed -i 's/\bprefix[^ ]*/prefix/g' fileName
