Actually, the problem is that I'd like to remove any lines from a "text"
file which contain non-ASCII characters. "non-ASCII" may not be technically
correct; I'm referring to the normal characters which can be entered from a
keyboard, but NOT the control characters.
OS is FreeBSD. The man page for grep says there are some pre-defined
character classes which should let me do this, but I can't figure out the
right syntax. I could also do it with sed I suppose but don't know the right
RE. Can anyone help with an example?
Thanks.
