Ksh93, bash, ... give also little nicer syntax version for the arithmetic expansion .
You can put everything inside (( )) and use variables without dollar sign $.
This is not Posix compatible, but look easier to read. Works only in the arithmetic expansion using (( )).
In this example input values has saved to the array and to the string (inputstr).
Is there a command that sets a variable length?
I have a input of a variable length field but my output for that field needs to be set to 32 char.
Is there such a command?
I am on a sun box running ksh

Given a line of text in ksh:
string1 string2 string3 .....stringn
is there a way of automatically assigning each string to an array element? Or just different variables would do.
Thanks,

Hi,
I have an issue where i run an command in a shell script.
command >/dev/null
ret=$?
echo ret
If the command returns an error i'm redirecting it to /dev/null.
The prob is if an error comes it expects the user to press return to continue.
And hence the return is not echoed. and the end... (4 Replies)

max
MAX(3) 1 MAX(3)max - Find highest valueSYNOPSIS
mixed max (array $values)
DESCRIPTION
mixed max (mixed $value1, mixed $value2, [mixed $...])
If the first and only parameter is an array, max(3) returns the highest value in that array. If at least two parameters are provided,
max(3) returns the biggest of these values.
Note
Values of different types will be compared using the standard comparison rules. For instance, a non-numeric string will be com-
pared to an integer as though it were 0, but multiple string values will be compared alphanumerically. The actual value returned
will be of the original type with no conversion applied.
PARAMETERS
o $values
- An array containing the values.
o $value1
- Any comparable value.
o $value2
- Any comparable value.
o $...
- Any comparable value.
RETURN VALUES max(3) returns the parameter value considered "highest" according to standard comparisons. If multiple values of different types evaluate
as equal (e.g. 0 and 'abc') the first provided to the function will be returned.
EXAMPLES
Example #1
Example uses of max(3)
<?php
echo max(2, 3, 1, 6, 7); // 7
echo max(array(2, 4, 5)); // 5
// The string 'hello' when compared to an int is treated as 0
// Since the two values are equal, the order they are provided determines the result
echo max(0, 'hello'); // 0
echo max('hello', 0); // hello
// Here we are comparing -1 < 0, so 'hello' is the highest value
echo max('hello', -1); // hello
// With multiple arrays of different lengths, max returns the longest
$val = max(array(2, 2, 2), array(1, 1, 1, 1)); // array(1, 1, 1, 1)
// Multiple arrays of the same length are compared from left to right
// so in our example: 2 == 2, but 5 > 4
$val = max(array(2, 4, 8), array(2, 5, 1)); // array(2, 5, 1)
// If both an array and non-array are given, the array will be returned
// as comparisons treat arrays as greater than any other value
$val = max('string', array(2, 5, 7), 42); // array(2, 5, 7)
// If one argument is NULL or a boolean, it will be compared against
// other values using the rule FALSE < TRUE regardless of the other types involved
// In the below example, -10 is treated as TRUE in the comparison
$val = max(-10, FALSE); // -10
// 0, on the other hand, is treated as FALSE, so is "lower than" TRUE
$val = max(0, TRUE); // TRUE
