dscextract — extract a single file from a Debian source package

🚀 Quick Reference

Use Case	Command	Description
📂 Extract a file from a .dsc	dscextract dscfile file	Extract a single file from a Debian source package
📁 Extract file from debian/ subdirectory	dscextract package.dsc debian/control	Useful for files in debian/ without unpacking large tarballs
⚡ Fast mode (skip .orig.tar.gz fallback)	dscextract -f dscfile file	Avoid scanning .orig.tar.gz for source format 1.0

📖 SYNOPSIS

dscextract [options] dscfile file

📝 DESCRIPTION

dscextract reads a single file from a Debian source package. The idea is to only look into .diff.gz files (source format 1.0) or .debian.tar.gz/bz2 files (source format 3.0) where possible, hence avoiding to unpack large tarballs. It is most useful for files in the debian/ subdirectory.

file is relative to the first level directory contained in the package, i.e. with the first component stripped.

⚙️ OPTIONS

• -f “Fast” mode. For source format 1.0, avoid to fall back scanning the .orig.tar.gz file if file was not found in the .diff.gz. (For 3.0 packages, it is assumed that debian/* are exactly the contents of debian.tar.gz/bz2.)

🚪 Exit Status

• 0️⃣ file was extracted.
• 1️⃣ file was not found in the source package.
• 2️⃣ An error occurred, like dscfile was not found.

💡 EXAMPLE

dscextract dds_2.1.1+ddd105-2.dsc debian/watch || test $? = 1
