Development Text file line randomiser

Hi there, i have a textfile with a list of URLS in, one per line.

I need some sort of program to jumble up the URLS in the file (ie jumble up the lines) I want to do this hardcopy, so the jumble URLS's are ready to be read, rather than reading a random line.

ie

www.google.com
www.microsoft.com
www.bla.com

to

www.bla.com
www.google.com
www.microsoft.com

(Obviously with a lot more URLs!)

Thanks

Jon B

 

open it in excel - make sure you import it so that each line goes in a new row.
add a column of random numbers
sort it by the random numbers
copy, paste the urls back into the text file.

Theoretically, this should work, but in practice you seem to get the same result from shuffle() every time.

(It was more compact than this (ie; two lines) but due to differing php function returns, it had to be expanded )

PHP:

$chrFile = './urls.txt';
$arrURLs = file($chrFile);
shuffle($arrURLs);
$resFile = fopen($chrFile, 'w+');
fwrite($resFile, str_replace("\n\n", "", implode("\n", $arrURLs)));
fclose($resFile);

(I made the assumption that seeing as the last of your threads I answered was a PHP question, that PHP would be an ok language to solve this with)

 

That's probably because you haven't provided a seed for the random number generator.

Edit: Use php's php's srand function

 

Hence why I was a little miffed.

 

so JB, do you have a target language? do you need it done automatically?

 

The php thing worked a treat Thanks i can now do it automatically

 

I would instead put a number before the url ex.

1
google.com
2
bittech.net
3
something.com

pesudeo code
generate random number
read until end of file
if line = random number then
read one more line into a string and that is your random url
