Deleting folders across directories

I have a directory structure like this:

... / firstlevel / output / sub-(101-162) / ...

In each sub-XXX folder, I have the folders run_1, run_1.feat, run_1+.feat, run_1++.feat, run_2, run_2.feat, run_2+.feat run_2++.feat.

Is there a one-line command I can run to keep only the run_1++.feat and run_2++.feat folders for all sub-XXX folders?

In other words, for each sub-XXX folder, I want to keep the folders run_1++.feat and run_2++.feat and delete run_1, run_1.feat, run_1+.feat, run_2, run_2.feat, run_2+.feat.

Thanks!

There are 2 possible interpretations of your question depending whether you want to delete a sub-directory that would be named firstlevel/output/sub-101/foo/, or not.

Positive interpretation

If you want to delete all sub-directories named run_1, run_1.feat, run_1.+feat, run_2, run_2.feat or run_2.+feat (but keep firstlevel/output/sub-101/foo/), you can try:

ls firstlevel/output/sub-{101..162}/run_{1,2}{,{,+}.feat}/

If the list looks correct replace ls with rm -rf. Note: the trailing / prevents deletion of regular files, only directories will match. It could be that the list of directories to delete is too long and that you get an Argument list too long error. In this case you can try find:

find firstlevel/output/sub-{101..162} -maxdepth 1 -type d \
\( -name run_[12] -o -name run_[12].feat -o -name run_[12]+.feat \) -print

When convinced replace -print with -delete. If the argument list is still too long try to split the 101..162 range in several smaller ones:

find firstlevel/output/sub-{101..131} -maxdepth 1 -type d \
\( -name run_[12] -o -name run_[12].feat -o -name run_[12]+.feat \) -print
find firstlevel/output/sub-{132..162} -maxdepth 1 -type d \
\( -name run_[12] -o -name run_[12].feat -o -name run_[12]+.feat \) -print

Negative interpretation

If you want to delete all sub-directories not named run_1++.feat or run_2++.feat (including firstlevel/output/sub-101/foo/), you can try:

( shopt -s extglob; ls firstlevel/output/sub-{101..162}/!(run_[12]++.feat)/ )

The extglob option enables extended pattern matching operators, like !(pattern) that match anything except pattern. Running the list of commands in a subshell (the surrounding parentheses) limits the scope of extglob. Again, if the list looks correct replace ls with rm -rf. And again, if the list is too long you can try find:

find firstlevel/output/sub-{101..162} -maxdepth 1 -type d \
! -name run_[12]++.feat -print

When convinced replace -print with -delete.
