extracting numbers from strings

Hello all,

I am being dumb with this and I know there is a simple solution.

I have a file with the follwing lines

Code:

 bc stuff (more)...............123
 bc stuffagain (moretoo)............0
 bc stuffyetagain (morehere)......34
 failed L3 thing..............1
 failed this status.............24
 failed that status.............253
 failed some kind of check........0

I want to pull the numbers off the end of the lines. I can use cut but that is not very robust. I have been using sed but cannot get it to work properly.

I don't think this is very hard. It's been a long day.

Thanks!

XINETD.LOG(5)                                                   File Formats Manual                                                  XINETD.LOG(5)

NAME

       xinetd.log - xinetd service log format

DESCRIPTION

       A  service configuration may specify various degrees of logging when attempts are made to access the service. When logging for a service is
       enabled, xinetd will generate one-line log entries which have the following format (all entries have a timestamp as a prefix):

              entry: service-id data

       The data depends on the entry.  Possible entry types include:

              START       generated when a server is started

              EXIT        generated when a server exits

              FAIL        generated when it is not possible to start a server

              USERID      generated if the USERID log option is used.

              NOID        generated if the USERID log option is used, and the IDONLY service flag is used, and the remote end  does  not  identify
                          who is trying to access the service.

       In the following, the information enclosed in brackets appears if the appropriate log option is used.

       A START entry has the format:

              START: service-id [pid=%d] [from=%d.%d.%d.%d]

       An EXIT entry has the format:

              EXIT: service-id [type=%d] [pid=%d] [duration=%d(sec)]

       type can be either status or signal.  The number is either the exit status or the signal that caused process termination.

       A FAIL entry has the format:

              FAIL: service-id reason [from=%d.%d.%d.%d]

       Possible reasons are:

              fork           a certain number of consecutive fork attempts failed (this number is a configurable parameter)

              time           the time check failed

              address        the address check failed

              service_limit  the allowed number of server instances for this service would be exceeded

              process_limit  a limit on the number of forked processes was specified and it would be exceeded

       A DATA entry has the format:

              DATA: service-id data

       The data logged depends on the service.

              login       remote_user=%s local_user=%s tty=%s

              exec        remote_user=%s verify=status command=%s
                          Possible status values:

                          ok        the password was correct

                          failed    the password was incorrect

                          baduser   no such user

              shell       remote_user=%s local_user=%s command=%s

              finger      received string or EMPTY-LINE

       A USERID entry has the format:

              USERID: service-id text

       The text is the response of the identification daemon at the remote end excluding the port numbers (which are included in the response).

       A NOID entry has the format:

              NOID: service-id IP-address reason
