Error [solved] Help using head cmd, print 20 then the next 20 etc

Hi all,

I have a list of text, single column and I want to print the first 20, then the second 20 and so on. I was pointed to xarg to help with this, but can't get my head around how to use it.

Would be great if it would put them into separate files with a certain name.

Any suggestions would be greatly appreciated.

I've just found that split does what I need it to do.
Code:
split -l 10 file.txt

Apologies.
