This project has the code of the shell equiavalent of linux for assignment level in classes. This code can execute self made commands and system commands. To compile the code
gcc PersonalShell.c
It might show a warning regarding gets. But it will work fine.
Commands For system commands(ls,ls-l,mkdir,etc..)we have used a function from exec family called execvp. For output redirecting we have used the system command from exec family namely execlp. In this code to execute system commands we first fork the main process and execute the system commands while parent process wait for the child to finsih. We also used getcwd command to get the directory of the area where the code is present.
execvp
- This function is used to execute any built in function in linux.
execlp
- This function stops the running program and creates the image of the function passed to it and starts executing that function
Self Made commands would be
exit
