Linux, like Unix's father, can be operated only from the command line. All graphical environment (KDE, Gnome) and managers overlay windows are only on the console. This action is a deliberate, since the work from the command line allows quick and easy system administration, is ergonomic for the system (there is no undue burden on video), and enables easy automation of operations (there is no need to create scripts for the graphic interface). It is therefore expected that there should be no long here as in the evolution of Windows, which is the elimination of text to graphics. The basic message - bash shell
The Linux programs are written in different programming languages C, C + +, Perl, Awk, or others. They are a reliable intermediary between the kernel and the user. Coating System is a special program as a mediator between the system and the user. It contains a built-in commands, so that life becomes easier. There are several popular shells: bash, ash, csh. The most common is bash, which is included as the default shell in many Linux distributions. After the user logs on to the system automatically runs the script. Bashrc. It contains basic user input and is executed at each login. Another script,. Bash_profile is run at the first time you log on to the system.
History is in the command file. Bash_history. As a result, the bash shell you can arrow through top - down play earlier issued a command. Many hacking beginners forget about the existence of this file. Working with Linux in the console there are several sources of assistance programs: a directory of names in the documentation, help system man pages, info pages, and options to help - help in almost any program. Almost any program that responds to the inclusion of options - help or-h display a short information about how to use the application. In this way, we do not have to look in the documentation or textbooks party system. If the creator of the program or distribution considered it necessary to create a help page describing the system configuration and use of applications, it is following a man Program_Name. Mostly the one hand, in addition there are further listed in the section See also.
Info is a newer version of the man. It has the possibility to interactively switch between consecutive themes. Some descriptions of programs are already available in that form. The creators of the programs often provide documentation to your programs, describing exactly how to install and use applications. It is available in a subdirectory with the name of the directory / usr / share / doc. Often, however, we have a problem: what are the commands associated with that topic? And here comes to us with the help apropos command to search the available topics related themes man. Office serves as the parameter. |
