Regex - help remove a dot after two-factor code

I found a KM macro on the Internet, which copies the two-factor code to the clipboard.

This also works very reliably for me under macOS Big Sur and macOS Monterey.

However, I have an advertiser who puts a dot directly after the number code - 765452. - because the number code is the end of a sentence.

Could someone please help me with which input you have to add to the following script to get this dot removed.

sqlite3 "$HOME/Library/Messages/chat.db"   "select text from message order by date desc limit 1" | perl -lpe "s/.* (\d+) .*/\1/g"

Not absolutely sure, but try this instead of the above

perl -lpe "s/.* (\d+).*/\1/g"

so the full script would be:

sqlite3 "$HOME/Library/Messages/chat.db"   "select text from message order by date desc limit 1" | perl -lpe "s/.* (\d+).*/\1/g"

Thank you @tiffle for the quick reply :+1:

Your supplement is the right solution. Now it also works if a dot is placed directly after the two-factor code.

My interpretation of the regex that you changed to is that it will now "work if any series of characters, not just a dot, appears after the 2FA code." That's because " .* " matches any series of characters. If you just want it to match only a dot, I think you have to replace ".*" with "\."

The purpose of the regex is to extract the numeric code - whether followed by a dot or something else - which it does successfully @Sleepy :smiley:
