I want to discover wrong spelling of "FooBar" in sentence:
"This is a 'FooBar' example where I should match different spelling of fooBar such as:
foobar, FOOBAR or even fOoBaR but not foobarS!"
In this sentence, I would like to match words (in order):
fooBar, foobar, FOOBAR, fOoBaR
and not:
FooBar (correct spelling), foobarS (not the same word)
Is there an existing solution using Perl Regular Expression? This is intended to be used with grep -P
Thanks
