Today I had to update a set of installed packages from a folder, but in that folder there were some deb packages that were not installed and that I did not want to install, so I thought of doing a script that check if that package were installed and if so, update them with the deb file.<\/p>\n
Of course, the main issue here is that the deb package name is not the name of the package once installed (the deb is , say samba_1.2.3..deb while the package name would be just samba), so parsing basenames (and taking out the version numbers which where preceded by a _) was the clue here:<\/p>\n
