How can I append IPs (a whole class C range) to a file using shell scripting?

Question

How can I use shell scripting to append a range of IPs to a file?

Oh, or do you need it that way? `echo 192.168.0.{0..255} >> /path/to/file` — mailq, Nov 10 '11 at 19:25
Please, [classes don't exist from eons](http://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing). You are referring to a /24. — ata, Nov 10 '11 at 19:30

Try something like:

#!/bin/bash

for i in {0..255}
do
    echo 192.168.0.$i >>outfile.txt
done

The >> operator is used to append to a file.

Thank you so much!! ps.: I know I should have found it out by myself, but I know next to nothing about shell scripting, and was (am) dead tired after adding the whole /24 range by hand in a web console (Apache/Tomcat). I'll try not to ask stupid questions next time! – neotobe Nov 10 '11 at 22:07
