hi
the actuall requirement are as such


grep -n "end" $FILE | cut -f1 -d":"

here $FILE is variable which contains the path of the file which
need to be grepped.

i am performing this operation in a while loop,which reads from a file (say xx) and for each path given in file xx, it assign path to variable
$FILE and then perform the grep operation

if i just write the expression as given above in my script it gives error saying "grep: canot open file ......"

And if i perform in this way

eval grep -n "end" $FILE | cut -f1 -d":"

it gives proper result at the scree
i.e 200 (line number expected)

But now i want this line number to be store it in a variable instead displaying at the screen

HOPE so now you got my problem...

Thanks,

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)
