Bug extracting part of a text file

Hi guys

So I have a very large log file where each event is logged along with the time that it occurred.

So for e.g. The contents of the file look like:
Code:
...
12:00:07 event 0 happened.
12:01:01 event 1 happened.
12:01:05 event 2 happened.
12:01:30 event 3 happened.
12:02:01 event 4 happened.
12:02:40 event 5 happened.
12:03:40 event 6 happened.
12:04:06 event 6 happened.
...

I want to extract every thing in that file listed between a given start time and an end time.

so some thing like all events between
the first entry of 12:01:00 and the last entry of 12:03:59
and store them in a random text file. Note time stamps can be repeated and therefore I mentioned the first and the last entries.

And not all lines in the log file start with a time stamp. Some lines are just random information about the server etc. But I want to extract those lines as well.

Hope I have clarified my question.

And thanks in advance every one Smilie

Use CODE tags when posting code, data or logs for better readability and to preserve formatting like indention etc., ty.

XSelectInput(3) 						  XLIB FUNCTIONS						   XSelectInput(3)

NAME
XSelectInput - select input events SYNTAX
int XSelectInput(Display *display, Window w, long event_mask); ARGUMENTS
display Specifies the connection to the X server. event_mask Specifies the event mask. w Specifies the window whose events you are interested in. DESCRIPTION
The XSelectInput function requests that the X server report the events associated with the specified event mask. Initially, X will not report any of these events. Events are reported relative to a window. If a window is not interested in a device event, it usually propa- gates to the closest ancestor that is interested, unless the do_not_propagate mask prohibits it. Setting the event-mask attribute of a window overrides any previous call for the same window but not for other clients. Multiple clients can select for the same events on the same window with the following restrictions: o Multiple clients can select events on the same window because their event masks are disjoint. When the X server generates an event, it reports it to all interested clients. o Only one client at a time can select CirculateRequest, ConfigureRequest, or MapRequest events, which are associated with the event mask SubstructureRedirectMask. o Only one client at a time can select a ResizeRequest event, which is associated with the event mask ResizeRedirectMask. o Only one client at a time can select a ButtonPress event, which is associated with the event mask ButtonPressMask. The server reports the event to all interested clients. XSelectInput can generate a BadWindow error. DIAGNOSTICS
BadWindow A value for a Window argument does not name a defined Window. SEE ALSO
