3 Commands

In a command shell, everything is done by invoking commands. This chapter covers command invocations in Eshell, including the command history and invoking commands in a script file.

Unlike regular system shells, Eshell never invokes kernel functions directly, such as exec(3). Instead, it uses the Lisp functions available in the Emacs Lisp library. It does this by transforming the input line into a callable Lisp form.⁴
