Unix

a. Use a pipe and the grep command to show only the files in the /bin directory that begin with mk

b. modify the command below so that the error message will be suppressed (i.e. have the command display the files that exist, but not the error message for the non-existent file) ls /bin/true /bin/false /bin/maybe Explaination of b: Running the command displays following message: "ls: cannot access /bin/maybe: No such file or directory". Modify it to make it supress that message.
