Dollar sign ($)

Use the dollar sign to match the preceding, adjacent characters at the end of a string.

For example, `end$` matches the following:

  • Temporarily suspend
  • We're going off the deep end
  • Match the characters that prepend

However, `end$` doesn't match the following:

  • Temporarily suspend.
  • We're going off the deep end.
  • Match the characters that prepend.

The preceding three lines all end with nd. rather than the end characters that you're matching with the regular expression.

Use this type of regular expression to create segments, filters, or goal steps that match a URI. For example, if you're testing the efficacy of a new HTM version of a page versus an older HTML version, you can identify the versions separately by using regular expressions such as the following:

  • email-signup\.htm$
  • email-signup\.html$

Use the backslash to escape the dot and ensure that it is interpreted literally.
