Whenthe shell is started, it should take a user command as input,execute it and display the output. The following example shows anexecution of the shell. It displays the command prompt ‘uofmsh’ andtakes the user command‘ls’as input from STDIN. It then executes thecommand ‘ls’ and prints the output to STDOUT.
Implement the command cd in your shell using the chdir(2) systemcall. Make sure that ‘cd -‘ should change the directory to the lastdirectory that the user was in. Verify that the cd command workscorrectly by using the ‘pwd’ command which displays the currentworking directory.
