How do I write a regex to match any file that begins with “history_” except for “history_all”?
I think the easiest thing to do would be to split it into two tests:
/history_\w+/and then check that it isn’t equal tohistory_all.If you don’t want to split it up, you can use something like
/history_(?!all\b)\w+/.Here the
(?!all\b)is a negative lookahead, which can be read as “not followed byall[end of word]“.
