Just be careful with this approach. It includes non-word constituents, such as $500 or you might get a number like 159.500.3.24 or something like that.

Of course the down-side to the approach I stated (space sandwich) is if 500 is the first, last or only word of the line, so you need to consider if that's a possiblity. You can get around that like so:
Code:
grep -E " 500 |^500 | 500$|^500$" access

genpat

NSIS(1) 							      GenPat								   NSIS(1)

NAME

       GenPat - A program to create patch files in VPatch format.

SYNOPSIS

       GenPat [-R] [-B=64] [-V] [-O] [-A=500] [source] [target] [patch.pat]

DESCRIPTION

       This manual page documents briefly the GenPat command.

       This manual page was written for the Debian (TM) distribution because the original program does not have a manual page. Instead, it has
       documentation in the HTML format; see below.

       GenPat is a program that creates installer programs for Windows.

OPTIONS

       -R
	   Replace a patch with same contents as source silently if it already exists.

       -B=64
	   Set blocksize (default=64), multiple of 2 is required.

       -V
	   More verbose information during patch creation.

       -O
	   Deactivate match limit of the -A switch (sometimes smaller patches).

       -A=500
	   Maximum number of block matches per block (improves performance). Default is 500, larger is slower. Use -V to see the cut-off aborts.

EXIT STATUS

       0
	   Success

       1
	   Arguments missing

       2
	   Other error

       3
	   Source file already has a patch in specified patch file (=error)

SEE ALSO

       GenPat is documented more fully in the HTML file /usr/share/doc/nsis/Docs/VPatch/Readme.html.
