📖 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).
