JIGDO-LITE(1)JIGDO-LITE(1)NAME
jigdo-lite - Download jigdo files using wget
SYNOPSIS
jigdo-lite [ URL ]
DESCRIPTION
See jigdo-file(1) for an introduction to Jigsaw Download.
Given the URL of a `.jigdo' file, jigdo-lite downloads the large file (e.g. a CD image) that has been made available through that URL.
wget(1) is used to download the necessary pieces of administrative data (contained in the `.jigdo' file and a corresponding `.template'
file) as well as the many pieces that the large file is made from. The jigdo-file(1) utility is used to reconstruct the large file from the
pieces.
`.jigdo' files that contain references to Debian mirrors are treated specially: When such a file is recognized, you are asked to select one
mirror out of a list of all Debian mirrors.
If URL is not given on the command line, the script prompts for a location to download the `.jigdo' file from. The following command line
options are recognized:
-h --help
Output short summary of command syntax.
-v --version
Output version number.
--scan FILES
Do not ask for "Files to scan", use this path.
--noask
Do not ask any questions, instead behave as if the user had pressed Return at all prompts. This can be useful when running jigdo-
lite from cron jobs or in other non-interactive environments.

CD images for Debian Linux can be downloaded with jigdo <URL:http://www.debian.org/CD/jigdo-cd/>.

Jigsaw Download <URL:http://atterer.net/jigdo/> was written by Richard Atterer <jigdo atterer.net>, to make downloading of CD ROM images
for the Debian Linux distribution more convenient.

MKIMAGE(1) General Commands Manual MKIMAGE(1)NAME
mkimage - Create an ISO image from jigdo files
SYNOPSIS
mkimage -j igdo -t emplate [options]...
mkimage -t emplate -z [options]...
mkimage -f d5-list -t emplate -M issing-list [options]...
DESCRIPTION
mkimage knows how to parse a jigdo template file, commonly used when creating Debian CDs and DVDs. It can be used to actually convert a
template file and associated files into an ISO image (hence the name mkimage), or with some command line options it will output useful
information about the template file instead.
-t template file
The jigdo .template file is the most important thing that mkimage needs, and must be specified for all operations.
-j jigdo file
The jigdo .jigdo file will normally acompany the .template file. To rebuild the image you must specify at least one of the jigdo
file and an MD5 file (-f).
-f MD5 file
A file listing files available locally and their MD5 sums, in the same format as used by genisoimage:
MD5sum File size Path
32 chars 12 chars to end of line
The MD5sum must be written in standard hexadecimal notation, the file size must list the size of the file in bytes, and the path must list
the absolute path to the file. For example:
00006dcd58ff0756c36d2efae21be376 14736 /mirror/debian/file1
000635c69b254a1be8badcec3a8d05c1 211822 /mirror/debian/file2
00083436a3899a09633fc1026ef1e66e 22762 /mirror/debian/file3
To rebuild an image you must specify at least one of the MD5 file and a jigdo file (-j).
-m item=path
Used in conjunction with a jigdo file; specify where mkimage should look on the local filesystem to find the files it needs to make
an image. (e.g. "Debian=/mirror/debian").
-M missing file
If you're not sure if you have all the files needs to create an image, specify both the jigdo file and an MD5 file along with the
template file and -M <file>. mkimage will check to see that all the files are available instead of building the image. Any files
that are missing will be listed in the file specified here. See jigit for usage examples.
-v Make mkimage more verbose. Additional -v arguments will make it more verbose again. Default level is 0 (almost no output). 1 will
print progress in % while the image is being created; 2 will list every file and data block that is appended to the image.
-l logfile
mkimage will normally write to stderr when it reports progress. Specify a logfile (or /dev/null) if you want it elsewhere.
-O Skip checking the validity of specified jigdo files. mkimage will normally check for the "JigsawDownload" header as a sanity check,
but some very old jigdo files produced by Debian pre-dated the addition of this header.
-o outfile
mkimage will normally write the ISO image to stdout, ready for piping into cdrecord or to iso-image.pl. Specify an output filename
if you want it written to disk instead.
-q mkimage will normally check the MD5 sum of every file it reads and writes, and will fail if it finds any mismatches. Specify -q to
tell it not to. This will normally run more quickly, but can leave you with a broken image so is POTENTIALLY DANGEROUS. Use with
care!
-s start offset
Rather than start at the beginning of the image, skip to the specified offset and start output there. Probably only useful in iso-
image.pl when resuming a download. Specifying a non-zero offset also implies -q, as it's difficult to check MD5 sums when you're not
checking the whole image. -e end offset Rather than end at the end of the image, stop at the specified offset. Probably only useful
in iso-image.pl when resuming a download. Specifying an end offset also implies -q, as it's difficult to check MD5 sums when you're
not checking the whole image.
-z Simply parse the template file and print the size of the image that would be generated, in bytes. Only needs the template file to be
specified, any other arguments will ignored.
EXAMPLES
mkimage -f MD5 -j test.jigdo -t test.template -M missing
Read in the files MD5, test.jigdo and test.template and check if all the needed files are available. If any are missing, list them
in missing.
mkimage -z -t test.template
Find out how big the ISO image would be from expanding test.template.
mkimage -v -f MD5 -t test.template -o test.iso
Build the iso image in test.iso, using files listed in MD5 to fill in what's needed by the template file test.template. Show
progress as the image is built.
