...but you can't cat gz files.
but we can use zcat.

Code:
zcat file_1.gz file_2.gz | gzip > output.gz

EDIT:
tried binlib suggestion and it also works...Smilie
Code:
cat file_1.gz file_2.gz  > output.gz

and we can append data directly into gz file also....
Code:
cat file_3.gz >> output.gz
cat file | gzip >> output.gz

NAME
bzexe - compress executable files in place SYNOPSIS
bzexe [ name ... ] DESCRIPTION
The bzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a penalty in performance). For example if you execute ``bzexe /bin/cat'' it will create the following two files: -r-xr-xr-x 1 root bin 9644 Feb 11 11:16 /bin/cat -r-xr-xr-x 1 bin bin 24576 Nov 23 13:21 /bin/cat~ /bin/cat~ is the original file and /bin/cat is the self-uncompressing executable file. You can remove /bin/cat~ once you are sure that /bin/cat works properly. This utility is most useful on systems with very small disks. OPTIONS
-d Decompress the given executables instead of compressing them. SEE ALSO
bzip2(1), znew(1), zmore(1), zcmp(1), zforce(1) CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the PATH environment variable to find gzip and some other utilities (tail, chmod, ln, sleep). BUGS
bzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases, using chmod or chown. BZEXE(1)
