Find everything after first comma in lines and remove it

Question

I have a file containing a bunch of lines like this blabla-any-characters**,**numbers-and-characters
I would like to keep everything before the first comma and remove everything else.
Any hint how to do this with awk or sed?
Thanks

Answer 1

You can use sed like this:

sed -i.bak 's/,.*$//' file

,.*$ will match anything after first comma and will replace it by an empty string.

-i.bak is for inline editing in sed.

Answer 2

Try this with cut:

cut -d ',' -f 1 file
