syntax to divide a number in a script

[brk6971]

Have a script that produces the sum of a column of numbers:
cat file |awk '{ sum += $1 } END { print sum }' >sum

Now I want to divide the sum by 1024 and have the output print on the screen.

No need for cat there.

Why not just repeat the command, adjusted slightly, unless of course it's a large input file:

awk '{ sum += $1 } END { print sum/1024 }' file

Annihilannic.

Thanks that worked. The file was not that large.
