I've had my brother in law look at this - its based around a university assignment... there are some basic stuff being fooled with like not being able to set variables

var="troy"

but i can put them in a text file and make them variables with a cat into the variable

anyway we've experimented and it appears the shell has been limited for some reason... in ksh

var="troy"

has no problem

so sorry for the bother everyone - this one seems to be something I need to take back to the lecturers. I've found ways to get around the limitations of what's going on but the time factor is killing me from the business end... had to knock back a good contract yesterday.

thanks for the help, it was crucial to my understanding and invaluable to my being able to successfully get past the hurdles.

no doubt i will have more questions on the weekend Smilie

NAME
shift - shell built-in function to traverse either a shell's argument list or a list of field-separated words SYNOPSIS
sh shift [n] csh shift [variable] ksh * shift [n] DESCRIPTION
sh The positional parameters from $n+1 ... are renamed $1 ... . If n is not given, it is assumed to be 1. csh The components of argv, or variable, if supplied, are shifted to the left, discarding the first component. It is an error for the variable not to be set or to have a null value. ksh The positional parameters from $n+1 $n+1 ... are renamed $1 ..., default n is 1. The parameter n can be any arithmetic expression that evaluates to a non-negative number less than or equal to $#. 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. ATTRIBUTES
