You need to verify that that downloaded Linux DVD or ISO images are intact before you burn and use them. This is security feature. But how do you verify ISO images?

dkopp is a Linux utility program for copying disk files to recordable DVD media. With dkopp, you can copy your files to DVD for safekeeping or archival storage, and verify that the copy is good (no read errors). dkopp is a free program licensed under the GNU General Public License.

Applications can create a lot of temporary files sometimes, and these files aren’t always cleaned up automatically. An example of this is when you run Python applications. Particularly if you’re a Python developer, your source code directories stack up with a .pyc version of each file, which is the cached compiled copy of the script.

The Secure Shell (SSH) and Secure Copy (SCP) make remotely performing system administration and copying files across secure links a painless operation. SSH and SCP use the same SSH protocol to protect network communications, but they rely on users knowing if they want a shell or to copy a file beforehand.

The Linux tee command is a way to write the standard output to a file. This is a little different from redirecting output to a file. In this case, the output is still send to standard out, but an additional copy is sent to create your text file.

An ISO file is the easiest and most universal method for backing up a DVD. The file is an archive file specifically for DVD VIDEO_TS and AUDIO_TS files, and is an exact copy of the disc. ISO files can be quickly burned to a new dvd using standard burning software, making it the optimal choice for storing backups.

Here's a little mystery for you. Imagine you have three files on a Windows machine called: HTML_File.htm, PDF_File.pdf and Text_File.txt. Windows will have no problem opening the appropriate program when you double-click them because of those three-letter extensions. If however you drop the extensions or mix them up, you'll have problems. Now copy the three files to a Linux machine.

Quick and easy way to use Perl's command line execution mode to copy timestamps to multiple files or directories.

One of the things I like about Linux is the command line. I have used nautilus, konqueror, and thunar to manage files in Linux and these file managers are great for what they do. But there are times when one simply wants to find a file when working on the command line without having to open a GUI application.
