the fugacious flag

~# cat Question

Allow me to tell a tale, one that will help in your journey...

nc challs.nusgreyhats.org 57812

Initially, this challenge involved displaying text one character at a time, followed by the flag. However, the flag would disappear immediately after appearing, requiring us to "catch" it.

What was the flag again? Let me try to recall...
Hmmm...
Hmm...
Hm...
flag{caught_the_flag_before_it_dissipated_into_nothingness_though_i_hope_you_didnt_use_a_screen_recorder_for_                                                                                                                  It appeared for 0.01 second but I forgot about it again...
If only we could *CAPTURE* the moment :(            

Sending the output

One way is to use a screen recorder and play it back but it was not efficient nor did it work well. Another way would be sending all the output to a file and then opening up the file to get the full flag.
