I am working on a shell program that needs to accept alpha-numeric input (i.e., P00375); when I use a simple 'read' statement to read in the input (i.e., read LOG), I receive the message "p00375: bad number". How must I adjust my input statement to accept alpha-numerics?
Thanks!

My thought was to use 'tr' with but the result is the opposite of what I want:

Hello,
I tried to write a bash script (code is below) that does scp files that contain a certain string, and that subsequently deletes only those files that have been copied (in my case new files are created every second so it is important to only delete those that have been copied).

intval
INTVAL(3) 1 INTVAL(3)intval - Get the integer value of a variableSYNOPSIS
int intval (mixed $var, [int $base = 10])
DESCRIPTION
Returns the integer value of $var, using the specified $base for the conversion (the default is base 10). intval(3) should not be used on
objects, as doing so will emit an E_NOTICE level error and return 1.
PARAMETERS
o $var
- The scalar value being converted to an integer
o $base
- The base for the conversion
Note
If $base is 0, the base used is determined by the format of $var:
o if string includes a "0x" (or "0X") prefix, the base is taken as 16 (hex); otherwise,
o if string starts with "0", the base is taken as 8 (octal); otherwise,
o the base is taken as 10 (decimal).
RETURN VALUES
The integer value of $var on success, or 0 on failure. Empty arrays return 0, non-empty arrays return 1.
The maximum value depends on the system. 32 bit systems have a maximum signed integer range of -2147483648 to 2147483647. So for example
on such a system, intval('1000000000000') will return 2147483647. The maximum signed integer value for 64 bit systems is
9223372036854775807.
Strings will most likely return 0 although this depends on the leftmost characters of the string. The common rules of integer casting
apply.
EXAMPLES
Example #1
intval(3) examples
The following examples are based on a 32 bit system.
<?php
echo intval(42); // 42
echo intval(4.2); // 4
echo intval('42'); // 42
echo intval('+42'); // 42
echo intval('-42'); // -42
echo intval(042); // 34
echo intval('042'); // 42
echo intval(1e10); // 1410065408
echo intval('1e10'); // 1
echo intval(0x1A); // 26
echo intval(42000000); // 42000000
echo intval(420000000000000000000); // 0
echo intval('420000000000000000000'); // 2147483647
echo intval(42, 8); // 42
echo intval('42', 8); // 34
echo intval(array()); // 0
echo intval(array('foo', 'bar')); // 1
?>
NOTES
Note
The $base parameter has no effect unless the $var parameter is a string.
