I am not familiar with the exact Posix regexp spec, mostly because
there are so many permutations of regexps in existence that I have
long since forgotten which is standard and whose interpretation if the
standard is correct.
So my fairly simple question is does the hackerlab regexp
implementation support expressions like:
\([a-z]+\),junk,\1
which might for example match the following lines
ron,junk,ron
parker,junk,parker
but not
ron,junk,parker
parker,junk,parke
Obviously this is a contrived example, but is germane to what how I
hope to use it.
