UNZCK(1)

💖 UNZCK — decompress a file in the zchunk format 💖

okay bestie, gather round, because unzck is here to un-squish your zchunk files and she is serving. 💅

✨ SYNOPSIS ✨

unzck [-c | --stdout] [--dict] [-v | --verbose] file
unzck -? | --help
unzck --usage
unzck --version

🦋 DESCRIPTION 🦋

The unzck utility extracts the original file from a zchunk-compressed one. that's it, that's the whole job, and she does it flawlessly, no notes. ✨

NOTE: the unzck utility will place the new file without the .zck extension in the current working directory, not in the directory where the original file resides. like, she's not gonna follow your file home, she's staying right here. 🏠💀 so if you run it from somewhere random, your output is gonna land somewhere random. plan accordingly bestie!!

The unzck utility accepts the following optional arguments:

• -c, --stdout — extract the data to the standard output stream, do not write it to a file. it's giving "just show me, don't save it" energy 🫶
• --dict — only extract the zstd compression dictionary. just the dict, nothing else, very niche very iconic 👑
• -v, --verbose — verbose operation; display some diagnostic output. she'll yap a little so you know what's happening 💬
• -?, --help — display program usage information and exit. the classic "wait how does this work again" move 🙈
• --usage — display brief program usage information and exit. short version, no yapping ✨
• --version — display program version information and exit. for when you need the receipts 📋

🌈 EXIT STATUS 🌈

The unzck utility exits 0 on success, and >0 if an error occurs. so like, zero = slay, anything above zero = something went sideways 😭

🎀 EXAMPLES 🎀

Create (in the current directory) an uncompressed words file from a compressed one:

unzck /mnt/xfer/words.zck

Do not create the words file, but send the contents to the standard output stream:

unzck -c /mnt/xfer/words.zck
