One of the most powerful features of the shell is chaining multiple commands together using pipes. Use the
commands cut, grep, sort and uniq to list the unique paths to the bash shell in the file /etc/passwd.
•/etc/passwd is delimited by : characters and the 7th field contains the path to the shell
•If you haven’t used cut before, you will want to look at the man page. Run man cut to read how this
command works.
•Build up each component of the pipeline one command at a time and see if the output is what you would
expect.
