find/grep returns no matches

Hi all!

I've faced with very unintelligible error using find/grep like this:

root@v29221:~# find /var/www/igor/data/www/ | grep u28507

I get nothing as a result, but:

root@v29221:~# grep u28507 /var/www/igor/data/www/               
$db_name = 'u28507';
$link = mysql_connect ('', '*', '*') or die ("Could not connect");

It drives me crazy, please help to figure this out.

You've taken the filename as input to grep, so you are grepping on the filename, not on the file contents, as you imagined.

try using
find ... | xargs grep u28507

or better
find ... | xargs -I{} grep u28507 {}

$ cat file1

$ find . -name file1 | grep u28507                   

$ find . -name file1 | xargs grep u28507 

$ find . -name file1 | grep file1
