SSH - Seperate grep results with a title - ssh

Question

I have 3 grep runs and results send to my email:
((grep -irl 'abc' /usr/www/users/FTPUSERNAME/*) && (grep -irl 'xyz' /usr/www/users/FTPUSERNAME/*) && (grep -irl 'xXx' /usr/www/users/FTPUSERNAME/*)) | mail me#mywebsite.com
However this creates a combined list of all files.
Is there a way to separate the results by inserting a title to each grep
So the email I get looks something like this:
Title for files with abc
/Path-To-File/filename.php
/Path-To-File/filename.php
/Path-To-File/filename.php
Title for files with xyz
/Path-To-File/filename.php
/Path-To-File/filename.php
/Path-To-File/filename.php
Title for files with xXx
/Path-To-File/filename.php
/Path-To-File/filename.php
Thanks for the help,
Amit

FWIW I wouldn't do 3 separate greps just for that and I also wouldn't use grep to find files when there's a tool with a very obvious name for that (find), e.g. with GNU awk for IGNORECASE and true multi-dimensional arrays:
find /usr/www/users/FTPUSERNAME/ -type f -exec awk '
BEGIN {
IGNORECASE = 1
split("abc xyz xXx",res)
}
{
for (i in res) {
re = res[i]
if ($0 ~ re) {
hits[re][FILENAME]
}
}
}
END {
for (i=1; i in res; i++) {
re = res[i]
printf "Title for files with %s\n", re
for (file in hits[re]) {
print file
}
print ""
}
}
' {} + |
mail ...
Note that given the above if you need to add a 4th regexp you just add it to the split() call, it only searches for files once instead of 3 times, you're only opening each found file once instead of 3 times, and you can format the output of the search however you like. There's various ways it could be optimized for speed if necessary.

You should be able to achieve this by pre-pending each of your grep commands with an echo. Here is your command slightly modified :
$ ((echo "Title for files with abc" && grep -irl 'abc' /usr/www/users/FTPUSERNAME/*) && ( echo "Title for files with xyz" && grep -irl 'xyz' /usr/www/users/FTPUSERNAME/*) && ( echo "Title for files with xXx" && grep -irl 'xXx' /usr/www/users/FTPUSERNAME/*)) | mail me#mywebsite.com
