The files was just an example, because it is easier to understand, what I mean (I thought)... But I want to Do it with the slacker tool. For example, the command looks like this:
slacker -aA br2:ffmpeg2/
Normally, it should select, and after an Ok reinstall all the packages at Your ffmpeg2 folder. But I am looking for a selector, which remove the rtmpdump package (just an example, I wanted to Do it with the ffmpegthumbnailer originally) from the auto selected ([ * ]) packages without
manual listing the package names, that I want to reinstall.
If I want to Do it with files, I Can redirect the ls output to a variable and after it, simply remove the file pathes, that are excluded. But with packages, that is more complicated...
Thanks nas-central the lot of help!
