Go into the editor and create the following two-line text file called ex6:

Last time I went to the beach I found a sea shell.

While in Kansas I found a corn shell.

Now append this line to your ex6 file:

The National Enquirer says someone gave birth to a shell, called the born shell.

Mail the ex6 file to yourself.

Using a pipe, count the number of lines (wc –l) in your ex6 file.

To list all set options, type the following:

set –o

Type the following at the command line:

cat << FINIS

Type the following at the command line:

kat file 2> error || print kat failed
