concatenate log file lines up to timestamp

Hi,

Using sed awk or perl I am trying to do something similar to

https://www.unix.com/shell-programmin...nk-line-2.html

but my requirement is slightly different. What I am trying to accomplish is to reformat a logfile such that all lines start with the timestamp line and any lines that do no start with a timestamp are appended to the last line with a timestamp. Optionally I would like to do this up to the first semicolon.

A simplified input would be somthing like this

2009-05-27 02:37:27.283 The quick
brown fox;
The quick
brown fox
2009-05-28 10:10:28.000 Mary
had a
little lamb.
2009-06-01 19:37:29.000 Jack and Jill ran up the hill;

and ideally the output would be

2009-05-27 02:37:27.283 The quick brown fox;
2009-05-28 10:10:28.000 Mary had a little lamb.
2009-06-01 19:37:29.000 Jack and Jill ran up the hill;

although this is also acceptable

2009-05-27 02:37:27.283 The quick brown fox; The quick brown fox
2009-05-28 10:10:28.000 Mary had a little lamb.
2009-06-01 19:37:29.000 Jack and Jill ran up the hill;

The log files can be up to 10MB in size and there can be a hundred lines or more between timestamps. The purpose of this is to format the file so that it can be loaded into a database.

Any suggestions/solutions would be greatly appreciated.

Thanks,
Alan

NAME
shell - run a command using shell SYNOPSIS
shell command [command] ... DESCRIPTION
The shell function concatenate its arguments, separating each by a space, and passes this string to the shell ($SHELL if set, otherwise /usr/bin/sh). EXAMPLES
Example 1: A sample output of shell command. Since the Form and Menu Language does not directly support background processing, the shell function can be used instead. `shell "build prog > /dev/null &"` If you want the user to continue to be able to interact with the application while the background job is running, the output of an exe- cutable run by shell in the background must be redirected: to a file if you want to save the output, or to /dev/null if you don't want to save it (or if there is no output), otherwise your application may appear to be hung until the background job finishes processing. shell can also be used to execute a command that has the same name as an FMLI built-in function. NOTES
The arguments to shell will be concatenate using spaces, which may or may not do what is expected. The variables set in local environments will not be expanded by the shell because "local" means "local to the current process." ATTRIBUTES
