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.

[/spoiler]

Bollocks.

Ah, nevermind. Turns out that

exec 1>/dev/tty

Does the job.

Please use [m] tags when pasting shell code. Syntax highlighting is too weird.

Yes:

exec 1>/dev/tty

No:

[code]exec 1>/dev/tty[/m]

AH AH FAGGOT

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.

>>8
Your hax0r name is withnail? Nobody is going to flame you or tell you how shit you are

>>9
I've used withnail for over ten years, picked it when I used to hang around efnet. Haven't been there in years, but I still use that name for this kinda shit.

I was never cool enough to get a quote submitted on bash.org ;_;

I suspect you're wrong.

Don't use this program to be a dick

FUCK YOU. YOU SUCK. YOUR PROGRAM SUCKS.

>>11
;_;

>>12

just re-release it without that pathetic warning problem solved

>>13
I wasn't really crying, nigga. The disclaimer is kinda a joke, as you can't really use the program to do anything bad on its own.

What really does need changing is that shit where if the checker file doesn't download. It needs exit 1; added in there.

Also, it's laughable to run the portscan, then have something that handles whether the network is up or not...that should really be first.

>>10

I was

exec &>/dev/null
OMG OPTIMIZED

>>15
Link please!
Yes, I'm jealous.

Vanity trips on my /pogs/? Terrible! Back to lounge with you!

>>16
Yeah, I found that out later. Should change that.

Bump for  >>15 to tell me what bash.org quote he got approved.

>>20
YHBT

>>20
Why don't you drop your trip, nigger? Only Cudder and Xarn are allowed to do that.

>>22
You're an idiot.

>>23
At least not dumber than >>20-san.
