Grep for multiple patterns over multiple files
- by prelic
I've been googling around, and I can't find the answer I'm looking for.
Say I have a file, text1.txt, in directory mydir whose contents are:
one
two
and another called text2.txt, also in mydir, whose contents are:
two
three
four
I'm trying to get a list of files (for a given directory) which contain all (not any) patterns I search for. In the example I provided, I'm looking for output somewhere along the lines of:
./text1.txt
or
./text1.txt:one
./text1.txt:two
The only things I've been able to find are concerning matching any patterns in a file, or matching multiple patterns in a single file (which I tried extending to a whole directory, but received grep usage errors).
Any help is much appreciated.
Edit-Things I've tried
grep "pattern1" < ./* | grep "pattern2" ./*
"ambiguous redirect"
grep 'pattern1'|'pattern2' ./*
returns files that match either pattern
