You are most welcome. Glad to hear the updated program is making your life easier.

I'll try and explain that code segment.

Firstly F has now special meaning and I picked the variable F to represent "Found". It's quite common here to use short variable names but for you own benefit later down the track I'd suggest using LinesFound or something like that.

F++ Has it's roots in the C programming language it increments the variable and could be also written as F=F+1 in basic and many other languages. Note if F is uninitialized (as in on the first matching line) it will be set to 1 by this command.

END{ if(F) print FILENAME":"F} The END condition is a special awk condition and only applies once after the all files have been processed. In this block we are testing our F variable and if it is non-zero we print the input file name followed by a colon character ":" and the F variable's value. This is to avoid printing "filename:" when no lines are found.

print - Output a string

SYNOPSIS
int print (string $arg) DESCRIPTION
Outputs $arg. print is not actually a real function (it is a language construct) so you are not required to use parentheses with its argument list. PARAMETERS
o $arg - The input data. RETURN VALUES
Returns 1, always. EXAMPLES
Example #1 print examples <?php print("Hello World"); print "print() also works without parentheses."; print "This spans multiple lines. The newlines will be output as well"; print "This spans multiple lines. The newlines will be output as well."; print "escaping characters is done "Like this"."; // You can use variables inside a print statement $foo = "foobar"; $bar = "barbaz"; print "foo is $foo"; // foo is foobar // You can also use arrays $bar = array("value" => "foo"); print "this is {$bar['value']} !"; // this is foo ! // Using single quotes will print the variable name, not the value print 'foo is $foo'; // foo is $foo // If you are not using any other characters, you can just print variables print $foo; // foobar print <<<END This uses the "here document" syntax to output multiple lines with $variable interpolation. Note that the here document terminator must appear on a line with just a semicolon no extra whitespace! END; ?> NOTES
Note Because this is a language construct and not a function, it cannot be called using variable functions. SEE ALSO
