From Wikipedia, the free encyclopedia
irssi IRC client running on a shell server

Traditionally a shell account was a user account on a remote server which gave you to access a Unix shell via a command-line interface protocol such as telnet or ssh.[1] They were originally provided by ISPs (such as Netcom (USA) and Digex) and were used for file storage, web space, email accounts, newsgroup access and software development.[2][3][4]

In more recent times, shell providers are often found to offer shell accounts at low-cost or for free.[5] These shell accounts generally provide users with access to various software and services including compilers, IRC clients, background processes, FTP, text editor (such as nano) and email client (such as pine).[6][7]

Shell accounts have been involved in illegal activity.[8][9][10] Some shell accounts are used to distribute warez.[11]

Once your modem connects to the other modem and you log in, it is the same as an xterm session or a console login (without graphics capabilities) on your Linux box, except that the remote computer you are logged into is connected to the Internet. You usually use a standard Unix shell, with roughly the same choices available on your own Linux system, although some shell accounts also provide an optional menu interface similar to what a BBS provides.{{citation}}: CS1 maint: date and year (link)
