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)

PDO_MYSQL-DSN(3) 1 PDO_MYSQL-DSN(3)PDO_MYSQL DSN - Connecting to MySQL databases
The PDO_MYSQL Data Source Name (DSN) is composed of the following elements:
o DSN prefix
- The DSN prefix is mysql:.
o host - The hostname on which the database server resides.
o port - The port number where the database server is listening.
o dbname - The name of the database.
o unix_socket - The MySQL Unix socket (shouldn't be used with host or port).
o charset - The character set. See the character set concepts documentation for more information. Prior to PHP 5.3.6, this element
was silently ignored. The same behaviour can be partly replicated with the PDO::MYSQL_ATTR_INIT_COMMAND driver option, as the fol-
lowing example shows.
Warning
The method in the below example can only be used with character sets that share the same lower 7 bit representation as
ASCII, such as ISO-8859-1 and UTF-8. Users using character sets that have different representations (such as UTF-16 or Big5)
must use the charset option provided in PHP 5.3.6 and later versions.
Example #1
Setting the connection character set to UTF-8 prior to PHP 5.3.6
<?php
$dsn = 'mysql:host=localhost;dbname=testdb';
$username = 'username';
$password = 'password';
$options = array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8',
);
$dbh = new PDO($dsn, $username, $password, $options);
?>

PDO_MYSQL DSN examples
The following example shows a PDO_MYSQL DSN for connecting to MySQL databases:
mysql:host=localhost;dbname=testdb
mysql:host=localhost;port=3307;dbname=testdb
mysql:unix_socket=/tmp/mysql.sock;dbname=testdb
Note
Unix only:
When the host name is set to "localhost", then the connection to the server is made thru a domain socket. If PDO_MYSQL is compiled
against libmysqlclient then the location of the socket file is at libmysqlclient's compiled in location. If PDO_MYSQL is compiled
against mysqlnd a default socket can be set thru the pdo_mysql.default_socket setting.
