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 very much depend on the program you re using  Different programs  Emacs  vi  sed  and Perl  use slightly different regular expressions  In this case  I d say that in the first pattern  the last     should be removed

a-z  0 10    should work     a-z  1 10    if you want to match at least one character  like    a-z     does

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

grep    0-9   1 16      wc -l   Gives the counts with exact match count with limit

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
