You may have a 32bit implementation of gzip -= the file command will show something like below - note the text in red. I would guess 32bit in your case.
I've noticed bzip2 gives a little bit better compression than gzip. So...I'm curious...what's gives the best compression out of all the compression utilities?
Thanks! (6 Replies)
Hi everybody,
Does anybody know,whether linux-2.4.20-8 supports predictor1 compression in PPP protocol support,as i was able to see there were only two compression techniques that r being supported i.e bsd and
deflate compression from "make menuconfig" under network device... (0 Replies)
Hello,
I have a .z file which i understand to be UNIX.
I'm on PC (no UNIX boxes) and have tried many different unzipping programs to extract this .z file, but only PicoZip has allowed me to view what is inside (telling me, i think, that it's not corrupt), but i have not been able to extract... (3 Replies)

Hi Everyone,
I am a Ph.D student working on some image processing tasks and I have run into an interesting problem that I thought someone on here might have an idea about. This paper discusses a method to compare two images based upon the amount they can be compressed. Sorry, since this is my... (3 Replies)
Hello everyone,
As the title suggests, I am attempting to test adding gzip compression to a connection to an application I am testing. Currently I have the application set up with httptunnel, which forwards the connection to the remote host.
I would like to use a script to intercept the... (5 Replies)
Hi all,
I am working on a sample backup code, where i read the files per 7200 bytes and send it to server. Before sending to server, i compress each 7200 bytes using zlib compression algorithm using dictionary max length of 1.5 MB . I find zlib is slow.
Can anyone recommend me a... (3 Replies)
How good is the compression rate of gzip when you use tar with the gzip option? I am pretty amazed that a 1 GB file was reduced to 1019K. This is what I did.
tar -cvf tar_test.tar.gz -T /list_of_files
ls -hl

gzexe
GZEXE(1) General Commands Manual GZEXE(1)NAME
gzexe - compress executable files in place
SYNOPSIS
gzexe name ...
DESCRIPTION
The gzexe 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 ``gzexe /usr/bin/gdb'' it will create the following two files:
-rwxr-xr-x 1 root root 1026675 Jun 7 13:53 /usr/bin/gdb
-rwxr-xr-x 1 root root 2304524 May 30 13:02 /usr/bin/gdb~
/usr/bin/gdb~ is the original file and /usr/bin/gdb is the self-uncompressing executable file. You can remove /usr/bin/gdb~ once you are
sure that /usr/bin/gdb 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 gzip(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 standard utilities (basename, chmod, ln, mkdir, mktemp, rm, sleep, and tail).
BUGS
gzexe 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.
