Bebiko Junior competition (

16/07/2013 Leave a comment

Friend of mine participate in competition on – just a simple vote system. Unfortunately I can’t see on which place she is, there is no such a functionality, so I need to implement it by myself. As usual I choice php for that:

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
$in = curl_exec($ch);

preg_match_all('/data-votes="(.*)" data-name="(.*)" data-id/i', $in, $out);
        echo $out[2][$i].';';
        echo $out[1][$i]."\n";

It will output a list of nicknames and votes in format:
Afterwards that output can be imported to excel and sorted.

Btw. Don’t forget to vote!

How to get fresh file/mysql backup from remote on minimal effort.

19/02/2013 Leave a comment

Lets assume that we have a remote web server (with ssh access) and we want fresh backup of files and mysql databases. Of course we can login, type some commands and then sftp those files but lets do this on minimum effort:

Backup files (tar, gzip and ‘download’ them):

ssh user2@remote "tar cf - /var/www/somepage | gzip -c" > files.tar.gz

Backup MySQL database:

ssh user2@remote "mysqldump -pXXXXXX database | gzip -c" > mysql.gz

Lets merge those command and write a little bash script that will automate those activities:

now=$(date +"%Y%m%d%H%M")
ssh user2@remote "mysqldump -pXXXXXX databases | gzip -c" > $bckdir/$now.mysql.gz
ssh user2@remote "tar cf - /var/www/somepage | gzip -c" > $bckdir/$now.files.tar.gz

XXXXXXX is a mysql password,
database is our db to backup.

Run command on each file in directory

19/02/2013 Leave a comment

Most useful when you have many files in directory and bash doesn’t want to cooperate:

-bash: -: Argument list too long

First one:

for file in *; do ls -al "$file"; done

where * could be a file name or extension ex.: *.jpg

And much more easy to remember:

find . -exec ls -al {} \;
