Preserving timestamp with -i switch

umasuresh has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,
Is there a way to preserve the timestamp while backing up a file using the -i switch?
e.g.

perl -e 's/old/new/g;' -pi.bak somefile

UPDATE Got it, thanks!
By default, this command preserves the timestamp!

Use -p option in cp to preserve mode, ownership, timestamp for i in `find . -type f -print`; do cp -p $i ${i}_bk;done	[reply] [d/l]
