📖 Features

Buildtins

Command	Option
`echo`	-n
`cd`	only with a relative or absolute path
`pwd`	none
`export`	none
`unset`	none
`env`	none
`exit`	none

Redirections

< must redirect the input.
> must redirect the output.
<< must receive a delimiter and read the given input until a line containing the delimiter. However, the history does not have to be updated!
>> must redirect the output to append mode.

Signals

ctrl-C, ctrl-D and ctrl-\ should work as in bash.

In interactive mode:

ctrl-C displays a new prompt on a new line.
ctrl-D exits the shell.
ctrl-\ does nothing

Pipe

| The output of each command in the pipeline is connected to the input of the next command by a pipe.

Quotes

Do not interpret unclosed quotation marks or special characters, such as \ (the backslash) or ; (the semicolon).
' (single quote) which should prevent the shell from interpreting the metacharacters characters present in the sequence between quotes.
" (double quote) which should prevent the shell from interpreting the metacharacters characters present in the sequence between quotes except the $ (dollar sign).
