Oddly enough just setting IFS to nothing seems to have fixed it.

I'm not entirely sure why, but gathered it would around the field separator.

I tried doing this :-

Code:
oldIFS=$IFS
IFS="\n\r"

if [ ....blah

IFS=$oldIFS

.and noticed it worked correctly but the print output from awk was missing n's and r's.

Through trial and error i found setting
Code:
IFS=""

made it work.

Anyone know why?

cheers

NAME

       times - shell built-in function to report time usages of the current shell

SYNOPSIS

   sh
       times

   ksh
       times

DESCRIPTION

   sh
       Print the accumulated user and system times for processes run from the shell.

   ksh
       Print the accumulated user and system times for the shell and for processes run from the shell.

       On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

       1.  Variable assignment lists preceding the command remain in effect when the command completes.

       2.  I/O redirections are processed after variable assignments.

       3.  Errors cause a script that contains them to abort.

       4.  Words,  following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
	   able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation  are  not
	   performed.
