Usage
dgrep is used like many standard Unix commands. The command with arguments is entered at the prompt, and output is sent to STDOUT with error messages directed to STDERR. The search pattern is case-sensitive and can be a single word, or a string in single quotes. You can even supply a Perl-compatible regular expression. You can obtain the Usage below if you type dgrep -h at your shell prompt.
Remember, you can use dgrep for any purpose, not just for searching the EE552 class notes.

-c Show only number of times pattern is found in each file
