I'm backing up one of my sites, and will be moving to another host. This was an expermintal site, and many of the directories won't be needed.
What tar command is needed to exclude directories from the compressed file? Could you also give an example.
also this might be the same comand, but -... (4 Replies)
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)
I have heard that bz2 compression a relatively new compression encoding algorithm, far superior to tar and gz. I also remember that I downloaded a FreeBSD LiveCD a while back that was only a couple hundred megs instead of the usual 650ish using bz2 - big difference, I'd say. But to the point, what...

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,
I have a question about finding the compression ratios of a zip (bzip2) file.I have written a procedure which upon certain criteria tar's and bzip2 certain directories and moves them to a near line storage.
Yesterday I happened to stumble upon it. The procedure has tared and bzipped 6... (3 Replies)

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
SEE ALSO debhelper(7)
This program is a part of debhelper.
