grep Follow-up: ctrl-char searching

[Charlie ROOT]

I was hoping for some sort of escape mechanism, such as
sed and tr use, i.e. grep $'\011'. When I get a new grep
I'll try the $'\t' trick -my current grep doesn't support it.

I found it was largely a shell issue. I use sh (Borne),
which does command line expansion upon receipt of a tab,
even if after a quote. Control-v immediately prints the
shell version number. I was able to create a file with a
tab and get it to work, as was switching to bash or csh.

Thanks again, Ian and Paul.
