#dar 3/ Dar's homepage is http://dar.linux.free.fr/ . As a simple file archiver tool, dar is great. Random access is preserved, you can compress with #gzip #bzip2 #lzo #xz #zstd or #lz4. You can encrypt with #GnuPG or symmetric #AES. You can stream if you want. You can split ("slice") across multiple media, and dar will prompt you for the slice(s) you need and seek you right to them.

That's cool, but we're just getting started.

#dar #gzip #bzip2 #lzo #xz #zstd #lz4 #GnuPG #aes

Today I learned: Linux has multiple cats. 😺

For every single file compressor: #gzip, #bzip2, #lzma, #xz, and #zstd, there is a matching cat command: zcat, bzcat, lzcat, xzcat, and zstdcat. #TIL #TodayILearned #Cats #Cat

#gzip #bzip2 #lzma #xz #zstd #til #todayilearned #cats #cat

You're familiar with #bzip2, but do you know why we don't have a "bzip"/"bzip1"?

bzip-0.21, released in 1997, used arithmetic coding. Due to patent infringement fears, the author changed to Huffman coding and released bzip2:

You can still get access to bzip-0.21 however:

@fuchsiii @puniko I did an emergency backroll of a production database literally on my 2nd day of work at a former employer because someone fecked up just minutes after I pulled a backup trying to esitmate it's size and working on a script to make it backup fast and space-efficient.

Gladly my inital backup was uncompressed, tho subsequent tests showed that the compression ratio achieveable was way beyond 1:5,2 just with #bzip2 out of the box.
