Hello Monks - not fit to carry your night soil out - I've been lurking my way round the site & decided to prey for help:

I would like to prefix a dot to all files that are older than xx days in a main directory and also those in its subdirectories.

I found this in the archives but have stalled

#! /usr/local/bin/perl
die unless chdir "/path/directory";
die unless opendir DIR, ".";
foreach $file (grep {-f && (14 < -M)} readdir DIR) { mv $file .$file;
} closedir DIR;

It would help me learn if someone could explain what {-f && (14 < -M)} does.
thanks
Mark
