Searching file containing dollar sign $ with grep

How do I search a file containing $using grep?

I've tried

grep "\$" file.txt

and it does not recognize the $ character to search for.

Actually grep \\$ file.txt works

As I posted in my comment,

grep "\\\$" file.txt

The first \\ is a literal \ for the regex engine, and the thrid \ is used to escape the dollar symbol.

A rule of thumb with matching a literal dollar symbol is:

  1. Escape up to 3 times
  2. Try doubling $ (i.e. $$)

Some of it should work.

Please see this answer in another stack exchange forum. Basically you should try grep '\$'.
