Shell Programming and Scripting

Hey guys.

I have been trying to figure out an easy way to seperate a liste of 150k numbers (10 digits) in a .txt file into odd and even numbers with each of their own files, for a project at work.

I've tried Excel, but it was too much for it and it wasnt very simple. So i gave up after struggling with it for days.

Im new to scripting and was told that this place would be able to assist me in my endevour, so im asking all the gurus in here, if you would please help me so that I can atleast try and look a bit good, for my new boss.

Thank you in advance, for any tips/hints/scripts you might have, that can aid me.

Code:

cat numberfile.txt | while read num
do

        if [ `echo "${num} % 2" | bc` -eq 0 ] 
        then  
                echo ${num} >> even.numbers.txt
        else
                echo ${num} >> odd.numbers.txt
done

Hi, try something like:

Code:

awk '{print>(FILENAME "." ($1%2?"odd":"even"))}' file

Try, untested

Code:

awk '{if ($0%2){print > "even"}else{print > "odd"}}' file

Do i have to make a seperate file for this one, so it opens the numbersfile.txt or? Not sure what im getting myself into

As i said, im new to this scripting and unix, so go easy on me

im guessing that FILENAME is the name of my file with numbers in it. And the file is the output? I seem to be getting an error saying something about it not being able to open "file".

You did not supply the name of your real .txt, so the helper used the name numbersfile.txt as a surrogate of yours. Just substitute this for yours.

Apply the same that above. Substitute file for your .txt

I think that i misformulated myself. Do i have to put that code into a file of its own and then run that? like javascript?
