I have a 5-column tab-separated file.
The only thing that I want to do with it is to split it.
However, I want to split it with a 80/20 proportion -- randomized, if possible.
I know that something like :
will work, but it only splits into equallly sized files -- and does not randomize.
Does anyone know if that is possible using awk/grep?
Every time we build an executable the date and time are put into the file, I need to run checksum on just the working lines.(IE, no header files)
Is this even possible, if so how would I go about it?
I am using a HP-UX server any help you can give me will be greatly appreciated.

split
SPLIT(1) General Commands Manual SPLIT(1)NAME
split - split a file into pieces
SYNOPSIS
split [ option ... ] [ file ]
DESCRIPTION
Split reads file (standard input by default) and writes it in pieces of 1000 lines per output file. The names of the output files are xaa,
xab, and so on to xzz. The options are
-n Split into n-line pieces.
-e expression
File divisions occur at each line that matches a regular expression; see regexp(6). Multiple -e options may appear. If a subex-
pression of expression is contained in parentheses (...), the output file name is the portion of the line which matches the subex-
pression.
-f stem
Use stem instead of x in output file names.
-s suffix
Append suffix to names identified under -e.
-x Exclude the matched input line from the output file.
-i Ignore case in option -e; force output file names (excluding the suffix) to lower case.
