[transacid]

just use "script". it's a bash builtin and designed for that purpose

@transacid: Great, I didn't know about this.  I'll play with it some.

Excellent tutorial!

if I cat my file once, it doubles the size. If I cat it again, it is 4 times as big. My trivia question: if i cat my file my output is writing to 20 times, and I start with a 1 mb txt file. How big will the file be when I am finished

[metalx1000]

@Droz42: 1048576 mb? Maybe :/

[Droz42]

@metalx1000

Yes, 2^20th which is 1048576mb, which is also exactly 1TB.

[metalx1000]

@Droz42: Isn't that interesting. Yeah, at first I tried 1^20th, which of course turned out to be 1. Then I realised it should be 2^20.

you can also try script for this, it lets you do some other things like put time stamps for commands

To dump scrollback buffer this works for me

cat /dev/vcs > screendump.txt
