Try to run it as sh:
# (I think it is in /usr/bin or was it #!/bin/posix/sh ??)
It will still use ksh, but it should emulate a POSIX shell...
(See man sh-posix)

I forgot, there is usually also a POSIX compliant ksh93 on HPUX:

Hello all. This is my first post/question on this site.
I’m a new Systems Analyst with previous experience with BASH. Although now I'm using AIX, and I’m trying to get a feel for the Korn shell (for those of you that don’t know AIX only uses the KORN shell).
I hope I put this into the correct... (10 Replies)

Hi all,
I am learning POSIX shell programming, and the book I read, uses the let command for integer arithmetic.
I have downloaded and use the shellcheck program on Linux.

Hi all...
This is just a fun project to see if it is possible to get a square root of a positive integer from 1 to 9200000 to 6 decimal places on a 64 bit architecture machine.
It is coded around dash and the results show the values from 0 to 10000.

list
LIST(3) 1 LIST(3)list - Assign variables as if they were an arraySYNOPSIS
array list (mixed $var1, [mixed $...])
DESCRIPTION
Like array(3), this is not really a function, but a language construct. list(3) is used to assign a list of variables in one operation.
PARAMETERS
o $var1
- A variable.
RETURN VALUES
Returns the assigned array.
EXAMPLES
Example #1
list(3) examples
<?php
$info = array('coffee', 'brown', 'caffeine');
// Listing all the variables
list($drink, $color, $power) = $info;
echo "$drink is $color and $power makes it special.
";
// Listing some of them
list($drink, , $power) = $info;
echo "$drink has $power.
";
// Or let's skip to only the third one
list( , , $power) = $info;
echo "I need $power!
";
// list() doesn't work with strings
list($bar) = "abcde";
var_dump($bar); // NULL
?>
Example #2
An example use of list(3)
<table>
<tr>
<th>Employee name</th>
<th>Salary</th>
</tr>
<?php
$result = $pdo->query("SELECT id, name, salary FROM employees");
while (list($id, $name, $salary) = $result->fetch(PDO::FETCH_NUM)) {
echo " <tr>
" .
" <td><a href="info.php?id=$id">$name</a></td>
" .
" <td>$salary</td>
" .
" </tr>
";
}
?>
</table>
Example #3
Using nested list(3)
<?php
list($a, list($b, $c)) = array(1, array(2, 3));
var_dump($a, $b, $c);
?>
int(1)int(2)int(3)
Example #4
Using list(3) with array indices
<?php
$info = array('coffee', 'brown', 'caffeine');
list($a[0], $a[1], $a[2]) = $info;
var_dump($a);
?>
Gives the following output (note the order of the elements compared in which order they were written in the list(3) syntax):
array(3) {
[2]=>
string(8) "caffeine"
[1]=>
string(5) "brown"
[0]=>
string(6) "coffee"
}
NOTES
Warning
list(3) assigns the values starting with the right-most parameter. If you are using plain variables, you don't have to worry about
this. But if you are using arrays with indices you usually expect the order of the indices in the array the same you wrote in the
list(3) from left to right; which it isn't. It's assigned in the reverse order.
Warning
Modification of the array during list(3) execution (e.g. using list($a, $b) = $b) results in undefined behavior.
Note
list(3) only works on numerical arrays and assumes the numerical indices start at 0.
