I'm working on a similar problem. Perhaps it's okay to piggyback on the thread?

I've two files:

First file:

and the second:


I'd like each input line from file1 to appear in the output, and if string2:string3 appears in file2, append :n1:n2 to the matching
line in file1.

(My awk is really rusty...)

Thanks for any pointers you can provide!

bool ctype_print (string $text) DESCRIPTION
Checks if all of the characters in the provided string, $text, are printable. PARAMETERS
o $text - The tested string. RETURN VALUES
Returns TRUE if every character in $text will actually create output (including blanks). Returns FALSE if $text contains control charac- ters or characters that do not have any output or control function at all. EXAMPLES
Example #1 A ctype_print(3) example <?php $strings = array('string1' => "asdf ", 'string2' => 'arf12', 'string3' => 'LKA#@%.54'); foreach ($strings as $name => $testcase) { if (ctype_print($testcase)) { echo "The string '$name' consists of all printable characters. "; } else { echo "The string '$name' does not consist of all printable characters. "; } } ?> The above example will output: The string 'string1' does not consist of all printable characters. The string 'string2' consists of all printable characters. The string 'string3' consists of all printable characters. NOTES
