Using the command shown underneath you can convert the movie extension .flv to .wmv real easily.

My server sends me a notifications for everything what happens on the server through e-mail, the only thing I had to check manually every time were the updates / upgrades for my Linux system. I figured there should be a way to get yum-update send notifications with available upgrades. So what we are going to do now is force yum to send an email when a update or upgrade is available.

First thing we need to do is open the yum config file.

Add these variables, and change “email_to” to your e-mail address:

Here is my working config file. You can also just copy and use this one and change the e-mail addresses.

After saving the file. Restart notification yum-updatesd service.

E-mail notification sample sent by yum notification.

Make a backup of a local hard disk on remote host via ssh.

Backup content of the hard drive to a file.

Make a copy of MBR (Master Boot Record) to floppy.

Restore MBR from backup copy saved to floppy.

Using “Dump”

Make a full backup of directory ‘/home’.

Make a incremental backup of directory ‘/home’

Restoring a backup interactively.

Using “Rsync”

Synchronization between directories.

Rsync via SSH tunnel.

Synchronize a local directory with a remote directory via ssh and compression.

Synchronize a remote directory with a local directory via ssh and compression.

Using “tar”

Make a incremental backup of directory ‘/home/user’

Using “SSH”

Copy content of a directory on remote directory via ssh.

Copy a local directory on remote directory via ssh.

Local copy preserving permits and links from a directory to another.

This gathers information about a domain name.

Query DNS servers for information about domain names

Ancient command to find out more information about DNS

Find the disk usage of a file or a directory.
(-sh = better readable | -ch = the same but larger output)

Disk freespace, pretty much self explaining but I use it with the -h switch to convert the bytes to megabytes or gigabytes

Find information about users.

Show who is logged on, and print: time of last system boot, dead processes, system login processes, active processes spawned by init, current runlevel, last system clock change.

But of course, you don’t want to be typing all that every time you want to update your twitter status. So I found this website which has a executable twitter bash script.

Replace the user and password with your twitter user id and password. Now save the text to a file called ‘twitter‘ and give the file execute permission. Put this file in any folder in your path. If you want to use this script everywhere on the server make sure it’s located in /usr/local/bin or ~/bin. If you are a user on the server, you may just create the file in your ~/user folder.

Now, how to use the script?

If you have created the twitter file in /usr/local/bin or ~/bin you may use this command anywhere you are in the server.

For best results, enclose the message within quotes. This will prevent problems when using wild card characters like ‘?’

And if have created the twitter file in your ~/user directory, make sure you are in the same folder as the file and then you may use this command.

Not working?

Did you make sure the file has executable rights?

You can check your server using the following command if you have already installed it or not.

If nothing shows up, install the package unrar. If you are using a Linux OS which uses yum update you can use the following command to install it.

If that does not work for you, you can simply install it manually using the next commands.

When that is all done, we can start using unrar. If you want to unrar multiple .rar files at once, you may use this command.

For example:

Output:

This example search for anything above 50MB.

This example search for anything above 100MB.

This example search for anything above 1000MB.

Modify your search changing the digit between the “+” and “M”.. Make sense right?

First we need a .mpg or .mpeg file. For example if you have an .avi file, convert this to .mpg (change pal-dvd to ntsc-dvd if needed)

Now we have the .mpg file we can set up the XML files with the settings for the conversion. Create spumux.xml and add the following settings into it.

You have to replace the filename, movie-width and the movie-height to your video preferences. You have seen them while converting if not use this command.

Now before we start processing, we need arial.ttf in our .spumux folder. If you don’t have a .spumux folder, create one;

OK — now we are all set, what you have to do now is use the following command.

Alright, when this is done we have to make another .xml file. Create dvd.xml and put this in there.

Obviously you have to change the vob file to your output video name. When you have done that we can do the following command.

You have just created a dvd including subtitles which you can enable or disable. What you got to do now is simply make a ISO or burn it directly to your blank dvd.

To make a ISO you can use this command:

If you want to burn it directly without making a .iso then use this command; (Replace /dev/scd0 with the device path to your DVD recorder)

The following code will create a full backup of your entire server. Excluding, /media, /proc and /var/spool/squid you might want to add or delete some excludes. Like /mnt, most servers mount devices in that folder. You need to exclude these as well. Also, You need to make sure you are creating your backup in a excluded folder/area. I make my backups in a mounted 30GB HD Device located in /media which is excluded.

If you only want to make a Backup from your /home and /root directory (which are probably the most important) just use this command:

Hope it works for you like it did for me, if you have any questions regarding to this post, please leave a comment so others can read it too.

It is actually easier then I thought, I have been spending almost a whole day to figure out how to add subtitles to an .avi file using bash. (Terminal) So I hope I can help you out with this one!

If it’s not working for you or you know other cool ways to do it, please leave a comment!
