$ man zcat
GZIP(1) GZIP(1)
NAME
gzip, gunzip, zcat - compress or expand files
SYNOPSIS
gzip [ -acdfhlLnNrtvV19 ] [-S suffix] [ name ... ]
gunzip [ -acfhlLnNrtvV ] [-S suffix] [ name ... ]
zcat [ -fhLV ] [ name ... ]
DESCRIPTION
Gzip reduces the size of the named files using Lempel-Ziv coding
(LZ77). Whenever possible, each file is replaced by one with the
extension .gz, while keeping the same ownership modes, access and modi-
fication times. (The default extension is -gz for VMS, z for MSDOS,
OS/2 FAT, Windows NT FAT and Atari.)
Thanks !! This code is working as expected. I tried with less than a million records in each file and it gave me the output in less than a minute. But when i tried with 27 million records in each file, it is still executing from an hour. Will this consume lot of disk space ? Is there a way to get the output faster ?
Hi there,

echo $line | grep $file > /dev/null
if

BTARCMP(1) General Commands Manual BTARCMP(1)NAME
btarcmp - a diff for Barry tar backup files
SYNOPSIS
btarcmp [-b][-d db][-D db][-h][-I charset][-P][-S][-v] tar0 tar1
DESCRIPTION
btarcmp takes two Barry backup tar files on the command line, and displays the differences it finds between them. If records can be
parsed, individual field differences are also displayed. Added and removed records are noted. Differences in database availability are
noted as well. If unable to parse the records, hex dumps are used.
OPTIONS -b Use brief filename markers. Useful when tar filenames are extremely long.
-d db Name of database to compare. Can be used multiple times to compare multiple databases. If not specified, all databases are com-
pared.
-D db Name of database to skip. Can be used multiple times. Overrides all other database selection options.
-h Show summary of options.
-I charset
Specifies the iconv charset to use for converting international strings. The Blackberry uses the WINDOWS-1252 charset, which is
incompatible with the more common code pages used in Linux. The most useful charset to use with this option is UTF-8, and is highly
recommended. Any other charset available via 'iconv --list' can be used here too, but may not be successful for some character con-
versions.
-S Displays list of known database records, which can be parsed.
-v Verbose output, which includes record data of added and deleted records in the output. If used twice, hex data is printed as well.
