How to grep '$$$$$'?
I want to check the absence of the following sequence of characters $$$$$ (i.e., 5 dollar signs) in a json file using grep as it has been used instead of comma to separate fields and I need to make sure this did not cause conflicts with existing similar sequence.
However, when I grep $, I get similar number of lines. It seems that $ is a special character for end of line?
How can i search for $$$$$ using grep?
Is $ a special character?

In addition, in shell unquoted$$is a special parameter which is replaced by the PID of the shell; this is commonly (and traditionally) used to create unique/nonconflicting names for temp-files and such.

It seems that $ is a special character for end of line?
Yep, exactly. And there's an end-of-line on each and every line.
You'll need to use $$$$$ as the pattern, or use grep -F '$$$$$', to tell grep to use the pattern as a fixed string instead of a regular expression.
