Question

I need to list all files with size > 0 under a directory (where it’s actually expected that the file size is 0). How can I do it with grep and/or awk? I was thinking of something like

$ ls -alR | grep ... | awk ...

Yet another find option:

find . ! -empty

update: (thanks to @steve comment)

If you need to list only files in only current directory:

find . -maxdepth 1 -type f ! -empty 

Note that -maxdepth is GNU feature. In POSIX environment there is another way:

find -type f -o \( ! -name . -type d -prune -false \) ! -empty
