How can I use regex to get all the characters after a specific character e g comma

Question

Need a Regex to get all characters after    not including it  from a variable  This variable can contain for example    SELECT   100E   7  24  SELECT   100E   7  1  SELECT   100E   7  286  SELECT   100E   7  5147   Note  There can be any length of characters after the   in this variable    An explanation of the regexp would be a added help for the novice     Edit  a javascript answer would be just as good

Short answer  Either       s S    or      to match everything after the first comma  see explanation for which one to use   or        to match everything after the last comma  which is probably what you want     You can use  for example          exec s  0  in JavaScript  where s is the original string  If you wanted to use multiline mode and find all matches that way  you could use s match        mg  to get an array  if you have more than one of your posted example lines in the variable on separate lines    Explanation     s S  is a character class that matches both whitespace and non-whitespace characters  i e  all of them   This is different from   in that it matches newlines       is a negated character class that matches everything except for commas    means that the previous item can repeat 0 or more times    is the anchor that requires that the end of the match be at the end of the string  or end of line if using the  m multiline flag     For the first match  the first regex finds the first comma   and then matches all characters afterward until the end of line   s S     including commas   The second regex matches as many non-comma characters as possible before the end of line  Thus  the entire match will be after the last comma

You can try with the following   new string   your string split      pop   trim      This is how it works    split      creates an array made of the different parts of your string    e g  if the string is   SELECT   100E   7  24   the array would be    SELECT   100E   7     24       pop   gets the last element of the array    in the example  it would be  24     This would already be enough  but in case there might be some spaces  not in the case of the OP  but more in general   we could have    trim   that would remove the spaces around the string  in case it would be   24     it would become simply  24     It s a simple solution and surely easier than a regexp
