Hi,
Someone at work told me that doing "du -a <DIR>|grep <FILE>" is faster
then "find <DIR>|grep <FILE>". I've measured, it doesn't looks quite
so. It did OTOH got me wondering what's the quickest way to answer if
file existed in a hierarchy of directories.
Assuming I'm not interested in any information besides the answer if
file existing or not. I would only need to access the directory
listing and not the inode of each file, right? Is there some utility
that can do this very simple search efficiently?
Why not use a find predicate for that?
Why not write a COBOL application that uses a FORTRAN subroutine to do
that ?
