RegexdrillAnchors: lines that start with ERROR
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 that begin with the word ERROR in capitals.
What this exercise teaches
^ERROR only matches when ERROR is the very first text on the line. Without the caret, ERROR in the middle of a line would count too.
A hint if you get stuck
The caret ^ outside brackets means the start of the line. The dollar sign $ means the end.
