I found somehow interesting command do specify disk usage which I am using without actually knowing what does the exclude pattern do. Instead excluding some locations or file names or just globs, the exclude pattern consists of the regular expression
Complete command is
du --exclude='*[0-9]G*' -hax / | grep '[0-9]G\>' but the first exclude parameter and the last grep parameter are a little bit confusing me as I thought on the first that I am excluding the exactly same parameter whih I am grepping later. Any help with these arguments would be appreciated.
