The objective of this project is to mimic the operation of bash with specific commands.
Mandatory part:
• Display a prompt when waiting for a new command.
• Have a working history.
• Search and launch the right executable (based on the PATH variable or using a relative or an absolute path).
• Not interpret unclosed quotes or special characters which are not required by the subject such as \ (backslash) or ; (semicolon).
• Handle ’ (single quote) which should prevent the shell from interpreting the metacharacters in the quoted sequence.
• Handle " (double quote) which should prevent the shell from interpreting the metacharacters in the quoted sequence except for $ (dollar sign).
• Implement redirections (< , > , << , >>)
• Implement pipes (| character). The output of each command in the pipeline is connected to the input of the next command via a pipe.
• Handle environment variables ($ followed by a sequence of characters) which should expand to their values.
• Handle $? which should expand to the exit status of the most recently executed foreground pipeline.
• Handle ctrl-C, ctrl-D and ctrl-\ which should behave like in bash.
• Your shell must implement the following builtins:
◦ echo with option -n
◦ cd with only a relative or absolute path
◦ pwd with no options
◦ export with no options
◦ unset with no options
◦ env with no options or arguments
◦ exit with no options
Bonus part:
• && and || with parenthesis for priorities.
To compile, go to the project path and run:
$ make Then, execute the program.
