Lushell is a command-line shell that embeds the Lua programming language directly into the shell environment. It combines classic shell functionality with the power and flexibility of Lua scripting.

• Classic shell functionality
• Lua scripting support
• Extended Lua functions for system calls (written in C)

Lushell introduces a special file extension, .lsh, which ensures compatibility with its extended Lua functions. These functions make it easy to interact with the file system and environment directly from Lua scripts.

• cd(path) -> boolean|nil, string|nil
  

Changes the current working directory to path. Returns true on success, or nil and an error message on failure.

• ls(path) -> table|nil

  Returns a table of filenames in the directory, or nil and an error message on failure.

• pwd() -> string

  Returns the current working directory as a string.

• mkdir(path) -> boolean

  Creates a new directory at the given path. Returns true on success, or false on failure.

• getenv(name) -> string|nil

  Gets the value of an environment variable, or nil if not set.

• setenv(name, value) -> boolean

  Sets an environment variable. Returns true on success, or false on failure.

• rm(path) -> boolean|nil, string|nil

  Removes a file at the given path. Returns true on success, or nil and an error message on failure.

• glob(pattern) -> table|nil, string|nil

  Expands a wildcard pattern into a table of filenames. Returns the matches as a table, or nil and an error message if no matches are found.
