arctic Posted January 9, 2006 Report Share Posted January 9, 2006 I just had a thought. When I install rpms with e.g. urpmi or apt-get or smart or ..., usually a lot of dependencies are met and other packages get installed, too. Now, let's say, I want to test some applications. I play around with them but after some weeks I forget about it and uninstall the apps. Now most of the rpms that were installed for meeting the dependencies are still installed as usually only the base app is removed. This blows up my system and uses up some "pretty" harddisk space. B) Twelve months later. My system is filled with unused rpms, but I can't remember which rpms are now "useless" on my system. Is there a command that can be launched for checking/scanning the system which rpms haven't been used in e.g. 2 months or one year, so I get a list of stuff I can uninstall? Or is there a command/script one could use for automatically removing rpms that were not used by the system in any way for a specified amount of time like e.g. one year? Or something similar?

Using the find command, there is a way to determine which files were last accessed more than x days ago. Since the find command can also apply another command to the results, we can use urpmf to then find what package the file was installed from. For example, if I want to see what files in /usr have not been accessed for at least the past 180 days, I could run the following command which will display the package plus the file name. find /usr -atime +180 -exec urpmf {} \; Example of what the above might output: printer-filters:/usr/share/doc/printer-filters-10.2/AppleStyleWriter/README.troubleshooting printer-filters:/usr/share/doc/printer-filters-10.2/AppleStyleWriter/Makefile.atalk Note: If you use the noatime option in fstab, then the system does not update access time and the above won't work.

scarecrow Posted January 9, 2006 Report Share Posted January 9, 2006 Arch's pacman does that: pacman -Rs useless Removes the package "useless", as well as all it's dependencies which aren't needed by other packages. Of course all will be listed, so you can checkout if you actually need any of them... Pacman does way more than that, but I guess this isn't enough to convince you trying Arch Linux (or Frugalware, which also uses pacman...) :P Quote Link to comment Share on other sites More sharing options...
arctic Posted January 9, 2006 Author Report Share Posted January 9, 2006 Ummm... I was just curious if anyone ever thought of what I explained earlier. I don't really want to change distros right now (I have a stockpile of distros running here) only because of that feature. I thoughta solution to such a "problem" could be useful for some people... BTW: I do have arch on a cd here. I simply haven't found the time yet to play around with it. Yoper bug-testing is more important for me and my co-developers at Yoper right now. ;) Quote Link to comment Share on other sites More sharing options...
