What will the '$' regular expression match?

The regex \$ matches a literal dollar sign character, not the end of a string. The plain $ metacharacter is the end-of-line/end-of-string anchor in many regex flavors, while \$ escapes it so it is treated as an ordinary character.

What it means

• $ by itself usually matches the position at the end of a line or string.

• \$ matches an actual $ symbol in the text.

• In engines that support multiline mode, $ can also match before a line break at the end of a line.

Example

• Pattern: price\$
• Matches: price$
• Does not match: priceUSD

Small caution

Regex behavior can vary a bit by engine, especially around line breaks and multiline mode, but the core rule is the same: escaped $ means a literal dollar sign.
