I am trying to use sed to strip out everything after the comma in a file that contains the following text:

#text1-text2,text1.text2,,,,text
#text31-text32,text31.text32,,,,text
etc

I want to be left with

#text1-text2
#text31-text32
etc

I am using sed for windows and the command I am using is:

sed "s/,*$//" < input.txt >output.txt

it is not working and I can't work out what I am doing wrong.

Can anyone help?

sed "s/,.*$//" < input.txt >output.txt


* in regular expressions is different than globs

* means "match the previous character 0 or more times"
. means "match any character"

Unfortunately I did manage to work it out last night, but your answer is bang on.  Thanks for the guidance.
