C_shell

• Summary:

  • This is a fully functional bash shell simulator written in C.
  • The following basic commands are directly handled by the shell:
    • "cd", "status", "exit"
  • All the other bash commands are handled by dynamically forked child processes.
  • Foreground mode can be toggled on & off by pressing Ctrl+Z. Once foreground mode is entered, all commands are handled as foreground commands.
  • All background processes are cleared manually from the process table by the shell once completed.
  • The program can be terminated only by entering "exit". All background processes will be terminated and cleared instantly from the process table upon termination.

• Please compile the "smallsh.c" program into an executable file using the following command:

  • gcc -std=c99 -o smallsh smallsh.c

• Please run the executable file using the following command:

  • ./smallsh
