Regular expression to limit number of characters to 10

Question

I am trying to write a regular expression that will only allow lowercase letters and up to 10 characters  What I have so far looks like this   pattern     a-z  0 10        This does not work or compile  I had a working one that would just allow lowercase letters which was this   pattern     a-z        But I need to limit the number of characters to 10

It might be beneficial to add greedy matching to the end of the string  so you can accept strings   than 10 and the regex will only return up to the first 10 chars     a-z0-9  0 10

You can use curly braces to control the number of occurrences  For example  this means 0 to 10      a-z  0 10      The options are     3  Exactly 3 occurrences   6   At least 6 occurrences   2 5  2 to 5 occurrences    See the regular expression reference   Your expression had a   after the closing curly brace  hence the error
