It's the shell's process id:

Code:
$ echo $$

30084

$ ps aux | grep '[3]0084'

user    30084  0.0  0.0   3156  1672 pts/1    Ss   09:38   0:00 -bash

$

I am just using it as a convenient, unique temporary file name.

pts_help

PTS_HELP(1)						       AFS Command Reference						       PTS_HELP(1)

NAME

       pts_help - Displays help for pts commands

SYNOPSIS

       pts help [-topic <help string>+] [-help]

       pts h [-t <help string>+] [-h]

DESCRIPTION

       The pts help command displays the complete online help entry (short description and syntax statement) for each command operation code
       specified by the -topic argument. If the -topic argument is omitted, the output includes the first line (name and short description) of the
       online help entry for every pts command.

       To list every pts command whose name or short description includes a specified keyword, use the pts apropos command.

OPTIONS

       -topic <help string>+
	   Indicates each command for which to display the complete online help entry. Omit the pts part of the command name, providing only the
	   operation code (for example, specify "membership", not "pts membership"). If this argument is omitted, the output briefly describes
	   every pts command.

       -help
	   Prints the online help for this command. All other valid options are ignored.

OUTPUT

       The online help entry for each pts command consists of the following two or three lines:

       o   The first line names the command and briefly describes its function.

       o   The second line lists aliases for the command, if any.

       o   The final line, which begins with the string "Usage", lists the command's options in the prescribed order. Online help entries use the
	   same symbols (for example, brackets) as the reference pages in this document.

EXAMPLES

       The following command displays the online help entry for the pts membership command:

	  % pts help membership
	  pts membership:  list membership of a user or group
	  aliases: groups
	  Usage: pts membership -nameorid <user or group name or id>+
	  [-cell <cell name>] [-noauth] [-force] [-help]
