grep :$ #will show all lines which end in :, this is a list of all the sub directories.

sed 's/:$//g' #removes the : from the end so you only get the full path of the directories, at this point if you want to limit which sub directories you can put in a grep statement.

awk '{print $1"/*"}' #formats the directory path to include all files in the sub directory you can change that to: awk '{print $1/"*.log"}' if you want log files only.

xargs cat #will run all of the arguments through cat which are piped into it, at this point you'd be running cat on all the files in all your sub directories

then obviously > will pipe it to a file


*edit* and yes i'm very bored at work.
Many thanks........

catman

CATMAN(1)						    BSD General Commands Manual 						 CATMAN(1)

NAME

     catman -- preformat man pages

SYNOPSIS

     catman [-fLnrv] [directories ...]

DESCRIPTION

     The catman utility preformats all the man pages in directories using the nroff -man command.  Directories may be separated by colons instead
     of spaces.  If no directories are specified, the contents of the MANPATH environment variable is used, or if that is not set, the default
     directory /usr/share/man is processed.

     The options are as follows:

     -f      Force all man pages to be reformatted even if the corresponding cat page is newer.

     -L      Process only localized subdirectories corresponding to the locale specified in the standard environment variables.

     -n      Print out what would be done instead of performing any formatting.

     -r      Scan for and remove ``junk'' files that are neither man pages nor their corresponding formatted cat pages.

     -v      Cause catman to be more verbose about what it is doing.

ENVIRONMENT

     LC_ALL, LC_CTYPE, LANG
	      These variables control what subdirectories will be processed if the -L option is used.

     MACHINE  If set, overrides the current machine type when searching for machine specific man page subdirectories.

     MACHINE_ARCH
	      If set, overrides the current architecture when searching for architecture specific man page subdirectories.

     MANPATH  Determines the set of directories to be processed if none are given on the command line.

FILES

     /usr/share/man  Default directory to process if the MANPATH environment variable is not set.

EXIT STATUS

     The catman utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     makewhatis(1), man(1), nroff(1)

HISTORY

     A previous version of the catman command appeared in FreeBSD 2.1.
