Hey,

yeah I tried that

but that will give everything greater than -3 and everything less than 2.

Code:
5
4
3
2
1
0
-1
-2
-3
-4
-5

So lets I wanted the range of values to be -3 to 2 then the values being pulled out would be

Code:
2
1
0
-1
-2
-3

but instead if I only reversed teh arrows, I get everything greater than -3 and everything less than 2

Code:
awk ' $2>=-2 && $2<=3'

this seems to work i think...

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
