find /path/to/folder/* -mtime +7 -exec rm {} \;

Please, note, that you need to keep spaces between command arguments.

This command is suitable for folders that contain a large number of files. In order to force file deletion you need to add -f key.

find /path/to/folder/* -mtime +7 -exec rm {} \;

If you need to move these files instead of deletion, here is the solution:

find /path/to/folder/* -mtime +7 -exec mv {} /path/test-mv-to/ \;

Hope this helps you to deal with archive files and big folders.

Let me mention that I don’t have a USB DVD-ROM drive, that’s why I had to deal with flash disks. I have tried to create some bootable flash drives, and let me share the software that has a simple and user-friendly interface, and, of course, it’s free. It is called WinSetupFromUSB and you can download it using the link above. It allows you to create a bootable installation flash drive to install almost any version of Windows you like.

I have tries some flash drives, but none of them allowed me to boot. I have tried all possible BIOS settings, but result was the same each time: error message telling me “Reboot and select proper boot device”.

The solution was very simple, yet not documented. If you need to boot your EEE 901 netbook from a flash drive, you have to try hitting and holding-down the [Esc] key when the ASUS splash screen appears during the boot-up process. It will then show you the boot menu. I can’t understand the reason, and there are no official docs from ASUS (I haven’t found any of them).

I would like to say a special thank you to guy from Eeeuser forum, their solution really helped me to find out the simplest way to boot from my flash drive.

kill `ps aux | grep php_script.php | grep -v grep | awk '{print $2}'`

What does this command actually do? It sends process IDs found by ps to the kill command. Then all these processes are killed. This command is used when any other methods, like killall -9 php are not acceptable for any reason.

The most common use of the sticky bit today is related to directories. When the sticky bit is set, only the item’s owner, the directory’s owner, or the root can rename, delete, or modify files. Without the sticky bit set, any user with write and execute permissions for the directory can rename or delete contained files, regardless of owner. Typically this is set on the /tmp directory to prevent users from deleting or moving other users’ files.

In order to set the sticky bit, a simple command is used:

chmod +t /tmp


In order to check whether the sticky bit is set, here is another command:

ls -ld /tmp

If you r last bit is ‘t’, then the sticky bit is set to the directory. It is a common practice to protect this folder in such a way as many server applications store their temporary data in this directory. For example, default MySQL configuration is set to store its socket file in /tmp/mysql.sock. You can experience problems if you don’t set a sticky bit on your /tmp directory.

./configure '--with-apxs2=/usr/local/apache2/bin/apxs' '--enable-calendar' '--enable-mbstring' '--disable-cgi' '--disable-magic-quotes' '--with-curl' '--with-curlwrappers' '--with-zlib' '--with-bz2' '--enable-ftp' '--with-gd' '--with-mcrypt' '--with-mhash' '--with-mysql=/usr/lib/mysql' '--enable-soap' '--with-xmlrpc' '--enable-zip' '--with-pear'

and the error you receive is:

/usr/bin/ld: cannot find -lltdl
collect2: ld returned 1 exit status
make: *** [libphp5.la] Error 1

Most probably you don’t have libtool-ltdl-devel installed. All you need is to install it using yum (or any other applicable package manager). yum install libtool-ltdl-devel. Then run ./configure, make and make install. This should do the job.

The solution is quite simple. If there were no changes made to user data, you should update your time. Yes, you should sync your server time to any time server. I can’t know the reason, but LR should ensure your time is correct before letting you use their API functionality. You can check Ntp Synchronisation setup or sync your time manually. Hope this saves you some time, as this feature is not documented.

I will show it as PHP code:

preg_match(‘/^(http:\/\/|https:\/\/)([^\.\/]+\.)*([a-zA-Z0-9])([a-zA-Z0-9-]*)\.([a-zA-Z]{2,4})(\/.*)?$/i’, $_POST['url']);

It will check whether url suits the pattern. May not be ideal, but it’s working.
