Utilities

Utilities facilitate tasks such as keeping the clock up to date, archiving utilities, and more.

Rename multiple files at once

Krename is a tool to rename multiple files in a batch. It allows multiple plugins to save or add information to files.

sudo apt-get install krename

Archiving Utilities

ZIP

The command-line terminal utility ZIP creates files that are compatible with the time-honored PKZIP and WinZip. It is included in (K)Ubuntu by default. Extracting zip files can be done with the unzip utility. Using the -P option allows the creation of a password for the zip file:

zip -r -P mypassword destination.zip *

Note: The -r option indicates to include all subdirectories recursively. The wildcard * adds all files in the directory, but you can specify individual filenames as well. If special characters are to be used in the password, designate them with a preceding \. For example, if the password is to be notsosecure123# then the command should be

zip -r -P notsosecure123\# destination.zip *

For more info, enter in the command-line terminal:

man zip

X-archiver (Archiving GUI)

Xarchiver is a GTK-based GUI front-end for many archiving utilities. It allows the addition of passwords. Install:

sudo apt-get install xarchiver

Ark (Archiving GUI)

Ark is a front-end for zip (and other archival utilities) but does not allow passwords. It is the default for KDE/Kubuntu.

BChunk

BChunk is a command-line utility that allows you to convert .cue and .bin files into an .iso file (so that they can be opened and manipulated in Kubuntu). Warning: If the bin/cue image has audio tracks, they will be lost.

Get BChunk

sudo apt-get install bchunk

To convert .cue and .bin files, navigate to the folder and run this command (replacing filenames with your own):

bchunk inputfilename.bin inputfilename.cue outputfilename.iso

After the file is converted into ISO you can mount it using:

sudo mount -o loop outputfilename.iso /media/output

Navigate to /media/output and you should see all the content there. You can then copy it anywhere.

To unmount:

sudo umount /media/output

HJSplit Files Joiner/Splitter

HJSplit for Linux (Java version).

  • Make sure you have Java Runtime Environment installed:
sudo apt-get install sun-java6-jre
  • Download the HJSplit JAR file:
wget http://www.freebyte.com/download/hjsplit/hjsplit_g.jar
  • Create the directory for HJSplit:
sudo mkdir /opt/hjsplit
  • Move the file to an appropriate directory:
sudo mv hjsplit_g.jar /opt/hjsplit/ 
  • Run:
cd /opt/hjsplit/ && java -jar hjsplit_g.jar 
Note: You could also make a terminal shortcut (menu item) in K Menu Editor.

Rar

Rar archives files into the proprietary .rar format.

sudo apt-get install rar

This application is a 40-day trial.

Unrar

Unrar extracts files archived with the proprietary .rar format. A free version can be installed:

sudo apt-get install unrar-free

or the proprietary version (also free for noncommercial use) can be installed with the kubuntu-restricted-extras package or with:

sudo apt-get install unrar

Once one of these two utilities is installed, you can use Ark to extract the .rar files.

7-Zip

The open-source 7-Zip archive format was originally designed for Windows (and DOS) but is also available for Ubuntu. The GNU/Linux version of 7-Zip does not come with a GUI, but Ark can hook into 7-Zip to handle 7z archives. Install:

sudo apt-get install p7zip-full

To allow the 7-Zip extension for Ark to extract .rar files, also install:

sudo apt-get install p7zip-rar

Hard Drive Utilities

KDiskFree (Hard drive properties monitor)

KDiskFree is a KDE utility for monitoring free disk space, etc.

sudo apt-get install kdf

Clock Utilties

Screensavers

A screensaver is useful as a security precaution as well as a power and screen element saver. Using even a simple "Blank Screen" screensaver with a password can slow a potentially malicious passerby from gaining access to your keyboard and computer while you are away from your desk.

K menu -> Settings -> System Settings -> Display and Monitor -> Screen Saver
  • Set a security password:
Screen Saver -> Require password to stop (ticked)

Run a media file as a screensaver

Video and other media can be run from the screensaver. Multiple files in random rotation can be used.

K menu -> System -> System Settings -> General -> Desktop -> Screensaver

-> Banners & Pictures -> Media Screen Saver -> Setup... -> Add..

Partition Managers

Also see these tips for partitioning scheme suggestions, other partitioning tools and methods, and usage of multiple partitions for multiple OSs.

GParted Partition Manager

Gparted is a GTK (Gnome)-based partition manager that can also be used with KDE.

  • This utility works best when run from a LiveCD. Recent versions of the Ubuntu LiveCD (but not the Kubuntu LiveCD) have a copy of GParted on them. Start the Ubuntu LiveCD in demo mode (not in install mode) and then start GParted:
Menu -> System -> Administration -> GParted
  • You can also install the package into your OS (once it is installed on your hard drive):
sudo apt-get install gparted

KDE Partition Manager

KDE Partition Manager is a KDE-based partition manager used during the installation of Kubuntu. It functions similarly to GParted (and can be used instead of GParted).

  • This utility works best when run from a LiveCD. Recent versions (Natty 11.04 or later) of the Kubuntu LiveCD (but not the Ubuntu LiveCD) have a copy of KDE Partition Manager on them. Start the Kubuntu LiveCD in demo mode (not in install mode) and then start KDE Partition Manager:
K Menu -> System -> KDE Partition Manager
  • If not already installed on your system:
sudo apt-get install partitionmanager
