Grep strings on multiple files and output to multiple files
Hi All,

I want to use egrep on multiple files and the results should be output to multiple files. I am using the below code in my shell script(working in Ksh shell). However with this code I am not attaining the desired results.

Code:
#!/bin/ksh
(
a="/path/file1"
b="path/file2"

for file in $a $b
do
egrep -iv '513|519|532' "$file" > test1 > test2
done
)
exit

The above code is resulting 2 files 'test1' and 'test2' whereas 'test1' does not contain anything in it(its empty file). 'test2' contains values of '/path/file2' whereas 513,519,532 records were ignored.

I want my results should be like below:

‘test1' should contain values of ‘/path/file1' whereas 513,519,532 records should be ignored. And
‘test2' should contain values of ‘/path/file2' whereas 513,519,532 records should be ignored.

Can anyone of you suggest me any solution on this ?

Thanks in advance.
Regards,
am24

dh_compress

DH_COMPRESS(1)							     Debhelper							    DH_COMPRESS(1)

NAME

       dh_compress - compress files and fix symlinks in package build directories

SYNOPSIS

       dh_compress [debhelperoptions] [-Xitem] [-A] [file...]

DESCRIPTION

       dh_compress is a debhelper program that is responsible for compressing the files in package build directories, and makes sure that any
       symlinks that pointed to the files before they were compressed are updated to point to the new files.

       By default, dh_compress compresses files that Debian policy mandates should be compressed, namely all files in usr/share/info,
       usr/share/man, files in usr/share/doc that are larger than 4k in size, (except the copyright file, .html and other web files, image files,
       and files that appear to be already compressed based on their extensions), and all changelog files. Plus PCF fonts underneath
       usr/share/fonts/X11/

FILES

       debian/package.compress
	   These files are deprecated.

	   If this file exists, the default files are not compressed. Instead, the file is ran as a shell script, and all filenames that the shell
	   script outputs will be compressed. The shell script will be run from inside the package build directory. Note though that using -X is a
	   much better idea in general; you should only use a debian/package.compress file if you really need to.

OPTIONS

       -Xitem, --exclude=item
	   Exclude files that contain item anywhere in their filename from being compressed. For example, -X.tiff will exclude TIFF files from
	   compression.  You may use this option multiple times to build up a list of things to exclude.

       -A, --all
	   Compress all files specified by command line parameters in ALL packages acted on.

       file ...
	   Add these files to the list of files to compress.

CONFORMS TO

       Debian policy, version 3.0
