what was ask for the projet

• Display a prompt while waiting for a new command.
• Have a functional history.
• Find and launch the correct executable (based on the environment variable PATH, or on a relative or absolute path).
• Do not use more than one global variable. Think about it because you will need to justify its use.
• Do not interpret unclosed quotes or unclosed special characters. requested in the subject, such as \ (the backslash) or ; (the semicolon).
• Handle ’ (single quote) which should prevent the shell from interpreting meta-characters present in the sequence between quotes.
• Handle " (double quote) which should prevent the shell from interpreting meta-characters present in the sequence between quotation marks except the $ (dollar sign).
• Implement redirects:
  • < should redirect the input.
  • > must redirect the output.
  • << must receive a delimiter and read the given input until encountering a line containing the delimiter. However, the history does not need to be updated!
  • >> should redirect output in append mode.
• Implement pipes (| character). The output of each command in the pipeline is connected to the input of the following command using a pipe.
• Manage environment variables (a $ followed by a sequence of characters) which must be substituted by their content.
• Manage $? which must be substituted by the exit status of the last pipeline executed in the foreground.
• Handle ctrl-C, ctrl-D and ctrl-\ which 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.
• Your shell must implement the following builtins:
  • echo and the -n option
  • cd only with relative or absolute path
  • pwd without any options
  • export without any options
  • unset without any options
  • env without any options or arguments
  • exit without any options

thout any options or arguments
