Is there an easy way to force
sort to ignore file extensions when sorting
find output by file name? I mean without extra scripting.
Not entirely sure what you mean.
But given a directory
$ ls bar.txt foo.abc foo.txt $
You can sort by just the name, stripping the extension, as below
$ find . -type f | sort -k 2,2 -t. -u ./bar.txt ./foo.txt $
As ever, an example of input together with desired output would help greatly.
