I made new version of "Pudd" [Puppy universal Disk Dump] script
and I do not know how to release this new version
how can it be in new puppy

in this new version I added compression and decompression
for images add options for split and PASSWORD protection
everything based on 7zip which [in old version] is in lucid 528


--------new--------new--------new--------new--------


now I add compression xz lzma and sfs with mount script inside
add md5 for every created files and sfx for *.7z files
problem only in lucid 528 with no 7zCon.sfx for 7zip sfx

I did not add network compression to stdout to nc if gz works others to
because I can not test it so ...

It is very good that you are working on Pudd. I wrote it a long time ago and it has not been maintained for years.

Your choice of compression/decompression with 7zip? That's in Lucid only though isn't it?

All puppies have tar and gzip/gunzip, generally better for Lunix work than using zip. Or bzip2/bunzip2, though that can be very slow on large files.

Better yet, all recent puppies have the 'xz' package, the best compression and fast. Recent puppies recognise the mime type of .tar.xz or .xz files.

Is there any way of making Pudd do the job faster?

I liked using it, but gave up because it was noticeably slower than the alternatives.

I am tired decompressing to tmp file every one file
so I add sfs compression with mount script works fast
but I can not find the way to write data to sfs by stdin
can someone tell me how to compress partition by squashfs
without first raw copy it to another partition
or by use other compression with mount mode
better if I can use it on most linuxs
or is there any special raw images compression with mount not sfs


I test on 2*1.7GHz cpu, 533 MHz ram speed, 120GB one hdd not sata
the 7zip compression with password protection
is between 2MB/s[7GB/h] to 7MB/s[25GB/h]
now I add 7zip STORE option zero compression 20MB/s[70GB/h]
so you can use only password protection and split option
gz compression is 10MB/s
and raw copy is 34MB/s[120GB/h]
for me it is fast

I read some of Pudd posts and every speed problems
I see is when Pudd write to USB which I can not test now
