Hi all.
I have 2 files like this:
f1
A 10
B 80
C 9
f2
A 11
B 700
C 10
What I want is the concatenation of the two files sorted by name (alphabetically) and size (numerically), so the result should be like this:
F3 (cat f1 f2 sorted)
A 10
A 11
B 80
B 700 (2 Replies)

Hi,
A basic query. In the example file below, I want to sort by column 1 and then by column 2 numerically. I have tried sort -k2n,1 file1 but while this sorts the columns in the correct order, it does not sort column 2 numerically. Any help would be much appreciated. Also, if you have time to...

Greetings - I'm not necessarily new to bash scripting - I'm probably between beginner and intermediate, but I have something that I just cannot figure out after many attempts to find it. I have a file that is merely a list of many files, with their respective paths, and a branch path (ClearCase)... (5 Replies)
Hey Guys,
I am facing an annoying scenario, fewer times when I execute the sort command, it throws out on error saying that "No Space on available on /var/tmp/<temp file name>. May be it is set to /var/tmp directory. I was wondering, if I cant redirect the temporary file creation to any other... (3 Replies)
Hello all,
I have a list of file names in a text document where each file name consists of 4 letters and 3 numbers (for example MACR119). There are 48 file names in the document (they are not in alphabetical or numerical order). I would like to reorder the list of names so that the 48th name is... (3 Replies)

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.
