grep & regex

[PaulBarbeau]

I am having problem locating a file with GREP and Regex can some help with the the line. I want to look for all files that have paul but not john in them.

Thanks for any help

The basic command is [tt]grep -l[/tt] which lists filenames containing matches

1. All text files containing paul
[tt]files=`grep -l paul *.txt`[/tt]

2. All the previous files not containing john
[tt]grep -v -l john $files[/tt]
