DCMD(1)

💅 DCMD(1) — the group chat manual page

okay bestie, welcome to dcmd, living in the General Commands Manual section of your local man pages. this is the little tool that makes your .dsc and .changes files stop being annoying. grab a boba, we're doing this. 🧋✨

---

🦋 NAME

dcmd — bestie's little helper that expands file lists of .dsc/.changes files right there in the command line 💖

---

✨ SYNOPSIS

dcmd [options] [command] [changes-file|dsc-file] ...

---

🌸 DESCRIPTION

okay so here's the vibe: dcmd goes through your command line and every time it sees a reference to a .dsc or .changes file, it swaps that reference out for the full list of files sitting in that file's 'Files' section — plus the file itself, obviously, she's not gonna ghost herself 💅

and like… why do we care? because it lets you mess with every single file involved in an upload (that's your .changes files) or every file in a source package (that's your .dsc files) without typing forty filenames by hand. it's giving convenience, it's giving main character energy. 👑

and if you omit command — meaning the first argument is an existing .dsc or .changes file — then she just prints the expanded list of files to stdout, one file per line. lowkey perfect for backticks. 🎀

---

💅 OPTIONS

so there's a whole lil menu of options you can use to pick out just a subset of the files listed in the .dsc or .changes file. and listen — if you ask for a file and it's not there, you're getting an error message. no cap. 😭

• --dsc — select the .dsc file.
• --buildinfo — select the .buildinfo file.
• --schanges — select .changes files for the 'source' architecture.
• --bchanges — select .changes files for binary architectures.
• --changes — select .changes files. implies --schanges and --bchanges. she contains multitudes 💖
• --archdeb — select architecture-dependent binary packages (.deb files).
• --indepdeb — select architecture-independent binary packages (.deb files).
• --deb — select binary packages (.deb files). implies --archdeb and --indepdeb.
• --archudeb — select architecture-dependent .udeb binary packages.
• --indepudeb — select architecture-independent .udeb binary packages.
• --udeb — select .udeb binary packages. implies --archudeb and --indepudeb.
• --tar, --orig — select the upstream .tar file.
• --diff, --debtar — select the Debian .debian.tar or .diff file.

---

✨ and here's the fun part: every single one of those options can be prefixed with --no to flip it — meaning "actually, select all the files that don't match this spec." iconic. 🦋

⚠️ but bestie, listen closely: you cannot combine positive filtering options (like --dsc) with negative filtering options (like --no-changes) in the same dcmd invocation. it's one or the other, no mixing. pick a lane, we're not doing chaos today 🙈

---

🫶 the extra lil options

• --no-fail-on-missing, -r — if any of the requested files were not found, do not output an error. (yes she's being forgiving. we love a chill queen.)
• --package, -p — output package name part only.
• --sort, -s — sort output alphabetically. tidy. organized. ✨
• --tac, -t — reverse output order. flip it, reverse it. 🔥
