.info

The domain name info is a generic top-level domain (gTLD) in the Domain Name System (DNS) of the Internet. The name is derived from information, though registration requirements do not prescribe any particular theme.

The info TLD was a response to ICANN's highly publicized announcement, in late 2000, of a phased release of seven new generic top-level domains. The event was the first addition of major gTLDs since the Domain Name System was developed in the 1980s. The seven new gTLDs, selected from over 180 proposals, were meant in part to take the pressure off the com domain.

The info domain has been the most successful of the seven new domain names, with over 5.2 million domain names in the registry as of April 2008. After the September 11, 2001 attacks in the United States, the Metropolitan Transportation Authority of New York switched to the easier to remember mta.info website to lead users to latest information on schedules and route changes on the area's transportation services. ICANN and Afilias have also sealed an agreement for country names to be reserved by ICANN under resolution 01.92.

Environment variable

Environment variables are a set of dynamic named values that can affect the way running processes will behave on a computer.

They are part of the environment in which a process runs. For example, a running process can query the value of the TEMP environment variable to discover a suitable location to store temporary files, or the HOME or USERPROFILE variable to find the directory structure owned by the user running the process.

They were introduced in their modern form in 1979 with Version 7 Unix, so are included in all Unix operating system flavors and variants from that point onward including Linux and OS X. From PC DOS 2.0 in 1982, all succeeding Microsoft operating systems including Microsoft Windows, and OS/2 also have included them as a feature, although with somewhat different syntax, usage and standard variable names.

Details

In all Unix and Unix-like systems, each process has its own separate set of environment variables. By default, when a process is created, it inherits a duplicate environment of its parent process, except for explicit changes made by the parent when it creates the child. At the API level, these changes must be done between running fork and exec. Alternatively, from command shells such as bash, a user can change environment variables for a particular command invocation by indirectly invoking it via env or using the ENVIRONMENT_VARIABLE=VALUE <command> notation. All Unix operating system flavors, DOS, and Windows have environment variables; however, they do not all use the same variable names. A running program can access the values of environment variables for configuration purposes.
