finding keywords in many files using grep
Hi to all
Sorry for the confusion because I did not explain the task clearly.
There are many .hhr files in a folder
There are so many lines in these .hhr files but I want only the following 2 lines to be transferred to the output file.
The keyword No 1 and all the words in the next line
They are
No 1
>UP20 ..................................
The word No 1 occurs only once in a file
I have some 4000 files and I want only these 2 lines from each file.
I hope the problem is explained ok.
thank you

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)
