List only executables installed by a debian package
I wanted to view only executables installed by a package. This seemed to work. There's got to be easier way, please share. Note: (1) Replace iptables with the package name of your interest (2) The command will trash any existing environment variable named 'lst' (3) Instead if you are interested in viewing just .ko or .so files installed by this package, then that would be easy: $ dpkg -L iptables | grep "\.[sk]o$"
