So it would be : 84,86,102

Given your input, one way would be:

Code:
$ perl -ne  'print $s=$s?",".$1:$1 if /Process ID (\d+):\d+ / && !$_[$1]++; print "\n" if eof' file
86,84,102

wsprintf(3C)						   Standard C Library Functions 					      wsprintf(3C)

NAME
wsprintf - formatted output conversion SYNOPSIS
#include <stdio.h> #include <widec.h> int wsprintf(wchar_t *s, const char *format, /* arg */ ... );); DESCRIPTION
The wsprintf() function outputs a Process Code string ending with a Process Code (wchar_t) null character. It is the user's responsibility to allocate enough space for this wchar_t string. This returns the number of Process Code characters (excluding the null terminator) that have been written. The conversion specifications and behavior of wsprintf() are the same as the regular sprintf(3C) function except that the result is a Process Code string for wsprintf(), and on Extended Unix Code (EUC) character string for sprintf(). RETURN VALUES
Upon successful completion, wsprintf() returns the number of characters printed. Otherwise, a negative value is returned. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | |MT-Level |MT-Safe | +-----------------------------+-----------------------------+ SEE ALSO
