💖 NAME 💖

igzip — compress or decompress files, similar to gzip, bestie 💅.

✨ SYNOPSIS ✨

igzip [options] [infiles]

🌸 DESCRIPTION 🌸

Okay so igzip compresses or decompresses files similar to gzip, and it does it using the ISA-L fast deflate library ✨.

The .gz files it outputs are compatible with gzip and [RFC-1952] 🫶.

The options are similar to gzip except — plot twist — --keep is the default 👑.

🎀 OPTIONS 🎀

  • -h, --help — help, print this message 🫶
  • -# — use compression level #, with 0 <= # <= 3 🔥
  • -o <file> — output file 💾
  • -c, --stdout — write to stdout 🌈
  • -d, --decompress — decompress file 🧚
  • -z, --compress — compress file (default) 💜
  • -f, --force — overwrite output without prompting 💀
  • --rm — remove source files after successful (de)compression 🗑️
  • -k, --keep — keep source files (default) 🎀
  • -S, --suffix <.suf> — suffix to use while (de)compressing 🦋
  • -V, --version — show version number 👑
  • -v, --verbose — verbose mode 📣
  • -N, --name — save/use file name and timestamp in compress/decompress 🏷️
  • -n, --no-name — do not save/use file name and timestamp in compress/decompress 🙈
  • -t, --test — test compressed file integrity 🔍
