It interprets the commands the user types in and arranges for them to be carried out. Staff and students in the school have the tcsh shell by default.

Filename Completion - By typing part of the name of a command, filename or directory and pressing the [ Tab ] key, the tcsh shell will complete the rest of the name automatically. If the shell finds more than one name beginning with those letters you have typed, it will beep, prompting you to type a few more letters before pressing the tab key again.

History - The shell keeps a list of the commands you have typed in. If you need to repeat a command, use the cursor keys to scroll up and down the list or type history for a list of previous commands. A file is a collection of data. They are created by users using text editors, running compilers etc. All the files are grouped together in the directory structure. The file-system is arranged in a hierarchical structure, like an inverted tree.

Several command-line interpreters that came later were inspired by the Unix shell. A simplistic and fundamental assumption of Unix was to create a newline-delimited text for almost all file formats. In the original version of Unix, there were no binary editors. What it means is that the entire system was based on textual shell command scripts. The common denominator in the input-output system was the byte. Text-based such processes made Unix pipes quite useful and promoted the development of simple and general tools to perform more complicated tasks.

Text-based applications have been proven quite popular in areas such as printing languages be it PostScript or ODF etc. Unix popularized regular expressions syntax that later became quite widespread. The uses of the Unix programming interface is now the basis for designing an operating system interface standard. Early Unix developers brought concepts like modularity and reusability into software engineering practice which was a great contribution actually.

The leading developers of Unix later established a set of cultural norms as well to develop software. These norms became an indispensable and influential guideline to Unix too. This created an Internet boom across worldwide with real-time connectivity and also formed the basis for deployment on so many other platforms. Unix is indispensable. From simple command-line applications to connecting and talking to servers, Unix made possible which GUI based other operating systems could not do.

Those prospective candidates who are to work with server technology and administration, should definitely learn Unix, get familiar with its commands, use cases, and core principle.

Particularly, those who handle Linux or Ubuntu systems or even those who want to go for big data analytics should surely learn uses of Unix. Simple applications of Unix commands such as pwd, chdir, dir, ls, ls-l, passwd should be known to all computer science graduates or computer enthusiastic.

This has been a guide to the uses of Unix in the real world. Here we have discussed the different applications of Unix like network protocol, command-line functionality, multitasking, etc. You may also look at the following article to learn more —.
