Counting lines starting with a certain string

grep '^your_word' /path/to/file | wc -l

[highlighter line=0]

Simple message with text in the body of the email

mutt -s "Test from domain" user@domain.com < /temp/message.txt

And if you need to send an attachment

mutt -s "Test from domain" user@domain.com < /temp/message.txt -a /temp/file.jpg

This is another way to write the test, having the body in the same line.

echo "This is the body" | mutt -s "Testing mutt" user@domain.com -a /temp/file.jpg
