Gnome Shell passe en 2.31.2 RC

inetd

Many times, you want to execute a command not only on one server, but also on several servers. For example, find out * Version of kernel * Version of Apache web server * Update static html or images files on all web servers via rsync * Find out user information, server information, memory usage etc * Security/patch checking tentakel I have already covered how to execute commands on multiple Linux or UNIX servers via shell script. The disadvantage of script is commands do not run in parallel on all servers. However, several tools exist to automate this procedure in parallel. With the help of tool called tentakel, you run distributed command execution. It is a program for executing the same command on many hosts in parallel using ssh (it supports other methods too). Main advantage is you can create several sets of servers according requirements. For example webserver group, mail server group, home servers group etc. The command is executed in parallel on all servers in this group (time saving). By default, every result is printed to stdout (screen). The output format can be defined for each group.

A google-interface behaves similar to a unix-shell. Several commands are available : mapsearch, translation, blogsearch, newsearch, and of course the traditionnal websearch. Love it.

A web site displaying a kind of Javascript shell

JS/UIX is an UN*X-like OS for standard web-browsers, written entirely in JavaScript (no plug-ins used). It comprises a vir- tual machine, shell, virtual file-system, process-management, and brings its own terminal with screen- and keyboard-mapping. For an overview of implemented commands have a look at the complete > JS/UIX-Manual-Pages; see also the > Version-History. The keyboard accepts the US-ASCII character set. As key-mapping depends from your browser, you may have to use the cursor and backspace buttons at the lower right of the terminal. A complete keyboard can be accessed at the lower left. Compatibility: Netscape 4+, MS IE 4+ and DOM-aware browsers.
