Features

Basics:

• Working History.
• Search and launch the right executable (based on the PATH variable or by using a relative or an absolute path).
• Environment variables ($ followed by a sequence of characters) expand to their values.
• ’ (single quotes: inhibit all interpretation of a sequence of characters).
• " (double quotes: inhibit all interpretation of a sequence of characters except for $.)
• $? expand to the exit status of the most recently executed foreground pipeline.
• | Pipes: The output of each command in the pipeline is connected via a pipe to the input of the next command.
• ctrl-C, ctrl-D and ctrl-\ work like in bash.

Redirections:

• < file: Redirect Input.
• > file: Redirect Output.
• << file: Read Input from the current source until a line containing only the delimiter is seen.
