[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.

ENVIRONMENT VARIABLES
The following environment variables affect the execution of head: Provides a default value for the internationalization variables that are
unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization vari-
ables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value,
overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes
of text data as characters (for example, single-byte as opposed to multibyte characters in arguments and input files). Determines the
locale for the format and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the
processing of LC_MESSAGES.
