A shell account is a user account on a remote server, traditionally running under the Unix operating system, which gives access to a shell via a command-line interface protocol such as telnet or SSH.
Shell accounts were made first accessible to interested members of the public by Internet Service Providers (such as Netcom (USA), Panix, The World and Digex), although in rare instances individuals had access to shell accounts through their employer or university. They were used for file storage, web space, email accounts, newsgroup access and software development.
Shell providers are often found to offer shell accounts at low-cost or free. These shell accounts generally provide users with access to various software and services including compilers, IRC clients, background processes, FTP, text editors (such as nano) and email clients (such as pine). Some shell providers may also allow tunneling of traffic to bypass corporate firewalls.
