[svlug] $GREP question

[Jesse Monroy]

There are two plain solutions you can use. One is with Lexx, the other
is with a scripting language, perl, python, tclsh, even bash.

This is the psuedo-code

while (<fid>) {
$data = $_;
if ($data =~ /begin/) {
    flag = 1;
} else if ($data =~ /end/) {
    print @collector
}  else {
   push (@collector, $data)
}
}

That's kinda perl
Lex example is here:
