Terminal Output Query

Postby Fat_Tuesday » Tue Aug 27, 2013 7:59 pm

Hi all, playing with nmap and it's taking a while. If I run a command in the terminal and get output from it, is it possible to get that output piped somewhere *after* the command has been run, or do I have to re-run the command with the pipe?

Cheers

Code: Select all
nmap -blah -blah -blah | tee output.log


will display the output from nmap as it's running while also sending the it to output.log
I have been touched by his noodly appendage.

Cheers Marty but I was hoping to capture the output that's already on display in bash, after the command has run. Other than copy n paste that is. I could have explained myself better but it's been a long day etc etc :-)

By definition a pipe can only redirect something that's in the process of "flowing". Given what you want, I don't see the problem with copy and paste.

Another option, that also requires you to know you want it in advance, is script.
