do you want the last updated file in a directory tree (no matter how old it
is), or the file(s) updated today (i.e within the last 24 hours)?
if the latter, then:
find /var/www/test -type f -a -mtime 0
find /var/www/test -type f -a -daystart -mtime 0
(for files modified since the start of the day)
see the man page for find(1) for more details.
the former could be done(*) with something like:
cd /var/www/test ; find . -type f -print0 | xargs -0 ls -lrt | tail -1
(*) for a very slack value of "done". i.e. only if the output
of find fits onto one command-line for xargs - which is why
the one-liner changes directory and searches ".", to make
the output smaller. if you have thousands of files or many
reallystupidlyveryunfeasiblylongfilenames under /var/www/test, you'd
need a better script :)
