Exclude files from cat command based on folder name
I want to concatenate several files in a whole bunch of subfolders. The list of files is always the same, but in each subfolder a different combination should be concatenated, the selection of which should be based on the subfolder name. The folder names contain permutations of Cr Hf Mo Nb Ta Ti V W and Zr. So for example one folder is called CrHfMoNbN, the next CrHfMoTaN and so on. The files to be concatenated contain these characters as well, they are called file_Cr, file_Hf, file_Mo, file_Nb, file_Ta, file_Ti, file_V, file_W and file_Zr.
What I need in the end should look like this:
cat file_Cr file_Hf file_Mo file_Nb file_Ta file_Ti file_V file_W file_Zr > newfile
but leaving out 5 of these files depending on if their character is present in the subfolder name or not. For example in the folder CrHfMoNbN the code should work like this:
cat file_Cr file_Hf file_Mo file_Nb {file_Ta file_Ti file_V file_W file_Zr} > newfile
where the files in {} are excluded from the command, in the folder HfTiVZrN it should work like:
cat {file_Cr} file_Hf {file_Mo file_Nb file_Ta} file_Ti file_V {file_W} file_Zr > newfile
The exclusion should work in a way that the alphabetical order is preserved, meaning that file_Hf always comes after file_Cr but before file_Mo. Ideally the command should be run from the parent directory for all contained subdirectories. I know that first step would be defining these letters as variables but onward i don't know what to do.
