How to use grep to look for files that have linex and liney

How can I use grep to find all files that have linex and liney ?
But not files that only have one of them ?

Thanks in advance.

grep 'linex\|liney' <files> or, to impress your friends grep 'line[xy]' <files>

You may have to escape the '|' more (or less) depending on your shell.

Thanks but on Tru64 Unix this does not work.

You might want to specify why this doesn't work for you. That'll help improving sigsegv's proposal.

Anyway, I'd suggest

Code:

grep -l linex <files> | xargs grep -l liney

I hope your filenames don't have spaces in them, otherwise this won't work either.

Groetjes,

The first one did not work because to test it I created 3 files testgrepx (x = null,1,2). One file had linex, one file line y and one both lines as sperate lines.
grep linex path/* found 2 files grep liney path/* found 2
but grep 'liney\|linex' path/* did not find any but did not give an error.

However your command did work thanks a lot and also thanks sigsegv. Maybe his did not work as I am using Tru64

Probably not escaped right for your shell. Getting regexes through the shell properly can be a bite sometimes...

If you can get it escaped right though, it's pretty standard. Should work fine just about anywhere.
