What is Korn shell (ksh)?
Career: Korn Shell
Korn Shell, often abbreviated as ksh, is a Unix shell developed by David Korn at AT&T Bell Laboratories in the early 1980s. It is both a command language interpreter and a scripting language that combines features of the Bourne Shell (sh) and the C Shell (csh), along with many new features. Korn Shell is known for its scripting capabilities, interactive use, and compatibility with other Unix shells. It is widely used for automating tasks, system administration, and as an interactive login shell. Its advanced scripting features, such as associative arrays and built-in arithmetic, make it a popular choice among Unix and Linux users.
