Roughly how many patterns? 20? 100_000_000? Is it a fixed set or
does it change a lot?
For 20 relatively static patterns, you can make a single regex. For
200 varying patterns you could use a shell loop to generate the
command line. For 100_000_000 patterns you're better off generating
a list of all the files and then combining the patterns into 50_000 or
so combined regexes.
IOW your optimal choice depends on, I think, details you didn't specify.
Could you provide more detail?
Thanks,
James.
