Hw-01 The Shell

Create new directory in tmp called missing

mkdir -p /tmp/missing

Look up touch command by man.

Look up chmod program

The user doesn't have any permission to execute, so we should chmod the permission.

chmod u+x ./semester

Then we should use sh to exec the file

sh ./semsester

Use | and > to write the “last modified” date output by semester into a file called last-modified.txt in your home directory.

cat ./semsester | grep last-modifiled > ~/last-modified.txt
