dscextract - extract a single file from a Debian source package
dscextract [options] dscfile file
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.
-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.)
0 file was extracted.
1 file was not found in the source package.
2 An error occurred, like dscfile was not found.
