I have a list of items that is generated with other code, and the result looks something like this:
text0161: "blah", text0162: "blah blah", text0163: "blah blah blah",
I need to take the very last line,
text0163: "blah blah blah", and remove the trailing comma, so it becomes
text0163: "blah blah blah".
At this point in my processing, there is nothing after
text0163: "blah blah blah", so I can just look for the very last line in the file and remove the comma. However, the contents of the line might change, so it won't always be exactly
text0163: "blah blah blah",. It might become just about anything else, like
text2020: "doobie doobie doo",.
I know I can use sed to delete the comma, like this:
sed -i 's@,@@g' file.txt
But I don't know how to only do that on the last line.
