Ubuntu

I need list of 3rd party softwares installed in a Unix server (eg: Fedora / RedHat). I know if they are system supported format (like rpm format for fedora/redhat, pkg format for debian/ubuntu etc) we can list them by system specific commands ($ rpm -qa). But how to list the softwares installed like tar format, gunzip format etc?? Please give me some idea how I can get the list.

Sincerely waiting for your response.

Thank you very much,

There is no easy way to do this apart from searching your system and looking in the places that they are likely to be found, e.g. /usr/someproduct, or /usr/local or /opt.

This is why it is a great advantage to find packaged software using the packaging tool of your operating system/distro rather than just install it manually. Obviously this isn't always possible, but if you are a disciplined administrator and always install software in logical locations then it shouldn't be too hard to keep track of.

A useful convention is to put stuff you have installed by hand in /opt or /usr/local and let the package management system completely reign over /usr/bin, /bin, /usr/sbin, etc.
