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
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.
