Grep Curly Braces aren't working

[Shaner Yo]

Hello,


I'm starting to use cygwin with grep command. Using curly braces with a
regex pattern is not working, even when I escape it. What am I doing
wrong?

 

I'm trying to search for four 0's in a row (Not using '0000') but none
of these work:

 

Grep 0{4}

Grep 0{0,4}

Grep 0\{4\}

Grep 0\{4}


Please tell me the answer, I've been googling for over an hour...

 

Thanks,
