question about grep, cut, and piping
Howdy folks,

I am fairly new to scripting but have lost of expirience in c++, pascal, and a few other. I am trying to complete a file search script that is sent a file name containing data to search that is arranged like this

"id","name","rating"
"1","bob","7"
etc

and an argument to search such as name=bob. My problem is that id and rating are both numerical so a simple grep won't work, so i need to search the correct field for the correct data. i need to then run a script(which i have already written and tested to work) that will accept the line numbers and the file name to print the lines that match. It is there where i am stuck.

Any suggestions how i can correctly print only the lines where the correct field matches? i can just forget the print lines script if there is an easier way that i missed. thanks for any help!

Mike

zgrep

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  is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep.  If no file is speci-
       fied, 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  zgrep  is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, zgrep uses
       it as the grep program to be invoked. For example:

	   for sh:  GREP=fgrep	zgrep string files
	   for csh: (setenv GREP fgrep; zgrep string files)
