Re: Perl process to constantly detect the time change of a file?

[stefp]

May be you want first to check out packages that do similar stuff like File::Tail, File::MultiTail and even POE::Wheel::FollowTail if you want to insert you stuff in an event framework. Even when I don't use a package or don't borrow code from it, I sometimes notice they deal with issues I had overlooked.

-- stefp -- check out TeXmacs wiki

[abstracts]

I think this is an excellent advice as it looks at the problem from a different perspective. Instead of polling the time the file was last changed, you wait for the file to change. (this of course assumes you can read from the file)

++stefp++

Update: Actually, coming to read the original post again, this will not work if the file is "touched" by another process, only if appended to. Nonetheless, --stefp++ :-)
