Bash STDOUT

I'm writing a script, and it's just about finished. Thing is, it calls a lot of sub-processes that spit terminal output to the screen. Now, I've figured out that you stop this with


exec 1>/dev/null 2>/dev/null

but I want to periodically re-enable STDOUT so I can echo updates about what the program is doing.

Any of you /prog/ geezers know what I should do?

Any and all answers appreciated. [spoiler]Yes, even you who is going to post REDIRECT MY ANUS.

Please use [m] tags when pasting shell code. Syntax highlighting is too weird.
For you, I will.

Here's the code in case anyone cares. It's not finished yet (obviously) as it's only testing on port 8080. Next time I have a session on it, I'm going to add commandline flags for which ports/how many IP's to scan.

I've left that in a cron job now I know it works. Maybe sometime before Christmas it will find me a a proxy instead of a device config page that's been left open to the net.

Disclaimer: If you want to run this yourself, you need to create /usr/bin/proxyharvest yourself, otherwise it won't work. I'm going to write a makefile for it which checks all relevant needed programs are installed and creates the directory it needs.

In before massive flaming and telling me how shit I am.
