Select files from a list of files

I have a list of filenames which look like this:

tRapTrain.Isgf3g.2853.2.v1.primary.RC.txt       tRapTrain.Yox1.txt
tRapTrain.Isgf3g.2853.2.v1.primary.txt          tRapTrain.Ypr015c.txt
tRapTrain.Isgf3g.2853.2.v1.secondary.RC.txt     tRapTrain.Yrm1.txt
tRapTrain.Isgf3g.2853.2.v1.secondary.txt        tRapTrain.Zbtb12.2932.2.v1.primary.RC.txt

Now i need to select the files with primary.txt and all the files where no final suffix is found. final suffix == primary.RC.txt , secondary.RC.txt, secondary.txt.

So my desired output will be:

tRapTrain.Isgf3g.2853.2.v1.primary.txt
tRapTrain.Yox1.txt
tRapTrain.Ypr015c.txt
tRapTrain.Yrm1.txt

I tried to do it with ls tRap*primary.txt but cant figure out how to do both selections at once. Any help is appreciated.

You can use find:

find * -type f -not -name "*.secondary.RC.txt" -not -name "*.primary.RC.txt" -not -name "*.secondary.txt" -print

Using Shopt:

$ shopt -s extglob
$ ls !(*primary.RC.txt|*secondary.RC.txt|*secondary.txt)

Meaning:

!(pattern-list)
Matches anything except one of the given patterns.

I would use an inverted grep match:

ls tRap* | grep -v "\.RC\." | grep -v "\.secondary\."

This should get rid of anything with ".RC." or ".secondary." in the title, which sounds like what you want.

This may not be the most elegant, but it works.
