[Nottingham] Help... How to grep four words in a file appearing in any permutation?

[Martin]

Just need the file names for files that have those four words.

There should be a surrounding 'white space' or end/start of line.

And the words can appear in any order in the file...


The words may well be on two adjacent lines, hence why the chain of
greps isn't the full answer...

?

Cheers,
Martin
