Speaking of which, how much speed is lost by starting up a process?

The idea of caching is that running

cat *; cat *; cat *; cat *; cat *

is probably slower than

cat * > baz; cat baz; cat baz; cat baz; cat baz; cat baz


Only for small files where the per file overhead of a read is significant.



But if the glued "file" is a stream (or pipe?) you can't do everything
with it (e.g. seek() ) that you could do with a proper file, right?


It does not need to be a pipe-like file. Seek can be implemented for a composite (glued) file.

You may want to do everything with it that you can do with a proper
file.
