Trying to read string "$$" from command line arguments

Question

I'm trying to get a string from the command line arguments, one of the arguments I'm trying to use is "$$". The argument resides in argv[2].

My program reads "$" fine (argv[2] = "$"), but when "$$" is used, argv[2] = "29628"....

Bash expansion of $$ ? Try echo $$... – Adam Sosnowski Feb 07 '15 at 18:49 — Adam Sosnowski, Feb 07 '15 at 18:49

Use a backslash to escape it: \$$.
