Hi Abdulkarim

I see, I'm using HP-UX 11.00 with a Korn Shell. I'm not sure how Sun 5.6 differs. What shell are you using?

I must admit I have not heard of the 'foreach' statement. Are you doing a shell script or using a programming language?

'fi' is the end of the 'if' statement. If statement syntax is as follows:

if <test>
then
<list of commants>
fi

I have redirected output to /dev/null because I don't want the result of the echo statement to appear on the screen. I just want to know the return value of the statement. If you don't already know, anything that goes to /dev/null 'disappears'. Its a bit like a waste bin.

Cheers
Helen

PPI::Statement::Null(3) 				User Contributed Perl Documentation				   PPI::Statement::Null(3)

NAME
PPI::Statement::Null - A useless null statement SYNOPSIS
my $foo = 1; ; # <-- Null statement my $bar = 1; INHERITANCE
PPI::Statement::Null isa PPI::Statement isa PPI::Node isa PPI::Element DESCRIPTION
"PPI::Statement::Null" is a utility class designed to handle situations where PPI encounters a naked statement separator. Although strictly speaking, the semicolon is a statement separator and not a statement terminator, PPI considers a semicolon to be a statement terminator under most circumstances. In any case, the null statement has no purpose, and can be safely deleted with no ill effect. METHODS
"PPI::Statement::Null" has no additional methods beyond the default ones provided by PPI::Statement, PPI::Node and PPI::Element. SUPPORT
See the support section in the main module. AUTHOR
