[SOLVED] - [ksh] finding last file with keyword in it

Why not loop up to five times through ls -t LOG_hostx* (watch out, no -r option!), grepping each file for "BEGIN"? If there's more than one BEGIN and you need the last one, try tacing the files.
Indeed, this was the solution, I was on the wrong track.
That happens when you are expanding the code, or when you adapt the code to little changes.
In my case, first the BEGIN/END sequence was in the last file only, then spread over 2 files, then over 3 and currently over 4.
So I kept looking for the next file, not paying attention to a sound solution.
Now it can be in any file, so is future proof.
Thanks for responding.

apropos
apropos(1) User Commands apropos(1)
NAME
apropos - locate commands by keyword lookup
SYNOPSIS
apropos keyword...
DESCRIPTION
The apropos utility displays the man page name, section number, and a short description for each man page whose NAME line contains keyword.
This information is contained in the /usr/share/man/windex database created by catman(1M). If catman(1M) was not run, or was run with the
-n option, apropos fails. Each word is considered separately and the case of letters is ignored. Words which are part of other words are
considered; for example, when looking for `compile', apropos finds all instances of `compiler' also.
apropos is actually just the -k option to the man(1) command.
EXAMPLES
Example 1: To find a man page whose NAME line contains a keyword
Try
example% apropos password
and
example% apropos editor
If the line starts `filename(section) ...' you can run
man -s section filename
to display the man page for filename.
Example 2: To find the man page for the subroutine printf()
Try
example% apropos format
and then
example% man -s 3s printf
to get the manual page on the subroutine printf().
