RegexdrillAnchors: lines that end with a period
A regex exercise from Regexdrill. Solve it with a pattern box with live highlighting in your browser, checked against hidden test strings, and it is checked the moment you submit.
The task
A match anywhere counts, so anchor the pattern yourself. Match lines whose last character is a period. A period followed by a space or anything else does not count.
What this exercise teaches
\.$ needs a literal period right before the end of the line. An unescaped dot would accept any last character, and without $ a period anywhere in the line would count.
A hint if you get stuck
$ outside brackets means the end of the line. The period is a special character, so escape it.
