/\b([a-z]*[A-Z][a-z]*){2,}\b/

    I tested in GNU/Screen and checked the source code. Both suggest that this is not possible. The search feature appears to support basic string matching only.

    What I suggest is that you use the tee command to send your program’s output to a file in addition to printing it. You can use Perl or grep on the file after that.

    $ your_program | tee your_program_output
$ grep pattern your_program_output
