Linux terminals share alot in common with their primitive ancestors such as vt100 like consoles. These early devices is capable of sending sequences that signaled events outside of the normal flow of typed characters, such as escape, tab, linefeed…etc. Linux uses CTRL key to send out these out of band signals. This article summarises many of the commonly used control sequences that are used in all Linux terminals.

CTRL-C
This is the most commonly used sequence. In the bash shell, CTRL-C will terminate any currently running process and return you to the bash prompt. For example, if you accidentally run a command that does not stop, use CTRL-C to cancel the command.

CTRL-D
Many Unix commands read their input directly from the keyboard. An example is the WC command. WC counts the number of lines, words and characters that a user types in from the keyboard. So if you tpye WC at the command prompt, the command will wait for your input till you use CTRL-D to signal the end of transmission.

CTRL-Z
CTRL-Z means to suspend a program. For example, you are working with a command and you want to stop it temporary as it is taking too long. To do that, you can use CTRL-Z. You can later restore back the command using the fg command.

CTRL-U
If you have messed up a certain command and you want to start all over, instead of using backspace, you can use CTRL-U. CTRL-U resets the current line.

CTRL-H
Instead of using the backspace key, you can use CTRL-H to function the same way. Unless the backspace key is malfunctioned or mapped wrongly, this sequence serves very little purpose.

CTRL-L
If your screen is too cluttered with unwanted information, you can clear the screen using CTRL-L.

CTRL-S
Freeze your screen. This is a good command to use if you decide to go for a coffee break and do not want any process to run till you are back.

CTRL-Q
This sequence is exactly the opposite to CTRL-S. If you have freezed the screen before, you use this command to unfreeze it.

CTRL-J
Functions the same way as the RETURN key.

CTRL-G
Makes a terminal beep sound for fun and entertainment.

Control Sequences are important to all Linux / Unix users. Some sequences are important while some are useless today. It is worth memorising the first few sequences as described in this article.

The smooth functioning of any organization depends on the effective storage, control, management and sharing of information. As the volume of documents increases, so does the challenge of managing the documents.

Document management software helps to create, name, file, store, retrieve and control the entire process of document management within an organization. It is designed to operate with ease large volumes of documents amongst a number of users.

Document management software is advantageous to those businesses whose cost of managing and storing paper-based documents is increasingly large. It is also beneficial to those whose nature of business requires them to easily access and exchange document-based information with the customers, vendors, partners and governmental agencies.

The software must facilitate multiple methods of indexing for future reference, and enable the user to find the right document among large volumes of data. It must provide for search capabilities to track versions of documents and efficiently retrieve related documents stored. The search feature must be easy and logical in its operation. Most importantly, the software must provide for security options that can be customized according to the business’ needs. The organization must have control over the department, group or user that has access to the document. Another significant factor is the ability of the software to safeguard the original document through its entire lifecycle.

Document management software must be capable of being installed on the company’s existing server, and must be accessible through the company’s intranet or website. It must be designed to integrate with the third party software applications, including scanning and imaging software. Files in any format, including images and multimedia files, should be capable of being uploaded as an attachment.

While selecting a software package, the most important aspect to be considered is its use to the organization’s business process. There are several software packages that offer a wide array of functions, ranging from the simple organization of documents to the management of sophisticated database and indexing systems. It is always advisable to go through a live demo to determine which software is best suited to the business. The ultimate goal must be reduced operating cost and time, and enhanced business prospects.
