These crons do not process every 30 mins. They process every hour. All the lines which contain three double-quote characters are syntax errors.
Please clarify.
This cron does not process every 5 mins between 3 and 4. More like 3 and 5 (but missing out exact hours).
The extra comma in "3-4," makes that line a syntax error too.
Please clarify.
Sorry, but you are asking us to simplify something which does not conform to specification at all. Also, all three lines contain syntax errors.
To answer your original question. Yes, it can be done with TWO entries (and no special Shell or whatever).
One cron to run every 30 mins and one cron to fill in the extra 5 mins intervals.

Why does this cron entry do nothing? It works interactively.

Thank you. (3 Replies)
I set up a job to run a script in a certain directory to remove certain files. The script seems to run as my logs indicate but nothing happens. If I run the script manually then it removes the correct files. I'm now wondering if crontab doesnt have access to remove files from the directory I'm... (9 Replies)
My question is how to specify the one-time execution of a shell script in crontab?
For example: If I wanted to schedule shell "Test.sh" for one-time execution on December 13 at 8:00AM would it be as follows?

LEARN ABOUT PHP
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.
