Thank you for that clarification. Although it took me a good while to mess around with it, I finally figured out what I had wrong. Truly, a novice mistake haha. But I understand the "select" statement now, and it has helped improve the script, and will help me improve other scripts that I write. Again, thank you for your time and knowledge, they have both proved to invaluable.
For those who care, the new script, which is fully operational, is as follows below.
Hi,
I am a newbie here. Trying to find a way of writing a script to launch multiple terminal or console windows on solaris 9. I used to be able to do this using cmdtool on older versions of solaris and it was even possible to configure the size and screen position of the window and the title. ... (5 Replies)
I developed a script in Lingon (which is an automated script editor developed for OS X) that is used to automatically restart programs only if they crash. The script itself does just that, but I only want it to load if I'm going to use the specific application that it's designed to protect. In... (3 Replies)

Hello All,
I have a text file containing output from a command that contains lots of escape/control characters that when viewed using vi or view, looks like jibberish. But when viewed using the cat command the output is formatted properly.
Is there any way to take the output from the cat... (7 Replies)

echo
ECHO(3) 1 ECHO(3)echo - Output one or more stringsSYNOPSIS
void echo (string $arg1, [string $...])
DESCRIPTION
Outputs all parameters.
echo is not actually a function (it is a language construct), so you are not required to use parentheses with it. echo (unlike some other
language constructs) does not behave like a function, so it cannot always be used in the context of a function. Additionally, if you want
to pass more than one parameter to echo, the parameters must not be enclosed within parentheses.
echo also has a shortcut syntax, where you can immediately follow the opening tag with an equals sign. Prior to PHP 5.4.0, this short syn-
tax only works with the short_open_tag configuration setting enabled.
I have <?=$foo?> foo.
PARAMETERS
o $arg1
- The parameter to output.
o $...
-
RETURN VALUES
No value is returned.
EXAMPLES
Example #1
echo examples
<?php
echo "Hello World";
echo "This spans
multiple lines. The newlines will be
output as well";
echo "This spans
multiple lines. The newlines will be
output as well.";
echo "Escaping characters is done "Like this".";
// You can use variables inside of an echo statement
$foo = "foobar";
$bar = "barbaz";
echo "foo is $foo"; // foo is foobar
// You can also use arrays
$baz = array("value" => "foo");
echo "this is {$baz['value']} !"; // this is foo !
// Using single quotes will print the variable name, not the value
echo 'foo is $foo'; // foo is $foo
// If you are not using any other characters, you can just echo variables
echo $foo; // foobar
echo $foo,$bar; // foobarbarbaz
// Some people prefer passing multiple parameters to echo over concatenation.
echo 'This ', 'string ', 'was ', 'made ', 'with multiple parameters.', chr(10);
echo 'This ' . 'string ' . 'was ' . 'made ' . 'with concatenation.' . "
";
echo <<<END
This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon. no extra whitespace!
END;
// Because echo does not behave like a function, the following code is invalid.
($some_var) ? echo 'true' : echo 'false';
// However, the following examples will work:
($some_var) ? print 'true' : print 'false'; // print is also a construct, but
// it behaves like a function, so
// it may be used in this context.
echo $some_var ? 'true': 'false'; // changing the statement around
?>
NOTES
Note
Because this is a language construct and not a function, it cannot be called using variable functions.
