Where is the copyright file applicable to libBLT.2.4.so.8.5 on Ubuntu?

Question

Please specify a location in /usr/share/doc/ if possible.

Answer 1

It's from the blt package. Unless Ubuntu has drifted far from its Debian roots, the copyright file will therefore be at /usr/share/doc/blt/copyright. It is also online at http://changelogs.ubuntu.com/changelogs/pool/main/b/blt/blt_2.4z-4.2/blt.copyright.

Answer 2

First, use

dpkg -S libBLT.2.4.so.8.5

to find the package name. Then use

dpkg -L <packagename> > /tmp/list

to list the files in the package. Then use

grep -i copyright `cat /tmp/list`

to find all files from the package that mention 'copyright'. One of them will probably be the file you're looking for.
