### Get a GREP #1!  125pts### Juliet hid a flag among 100,000 dummy ones so I don't know which one is real! But maybe the format of her flag is predictable? I know sometimes people add random characters to the end of flags... I think she put 7 random vowels at the end of hers. Can you get a GREP on this flag?### ### .The20thDuck### HINT : Look up regular expressions (regex) and the regex option in grep!~~

So , in [flag.txt](https://we.tl/t-8Qdb0xj1ac) we have more than 46k flag formati to filter we need to use this command : ** egrep "(o|i|y|e|a|u)(o|i|y|e|a|u)(o|i|y|e|a|u)(o|i|y|e|a|u)(o|i|y|e|a|u)(o|i|y|e|a|u)(o|i|y|e|a|u)}$" flag.txt**OR **egrep  [aeiou]\{7\}  flag.txt**
