Hi RudiC

I think I get what you mean. Need to get the hang of trying to understand these regex.
I tested as below.
It gives the output that am after.
Will try with the real file that I am wanting to change.

Code:
$: head -20 file*
==> file1 <==
/db/abcp/DIR/abcp_data_01.dbf

==> file2 <==
/db/abcp/DIR/abcp_data_01.dbf
   /db/abcp/DIR/abcp_data_02.dbf

==> file3 <==
/db/abcp/DIR/abcp_data_01.dbf
/db/abcp/DIR/abcp_data_01.dbf txt
   /db/abcp/DIR/abcp_data_02.dbf
$: sed 's#^\(/db/abcp/DIR/abcp\)\(_.*\.dbf\)$#/db/abct/DIR/abct\2#' file1 > file
$: cat file
/db/abct/DIR/abct_data_01.dbf
$: sed 's#^\(/db/abcp/DIR/abcp\)\(_.*\.dbf\)$#/db/abct/DIR/abct\2#' file2 > file
$: cat file
/db/abct/DIR/abct_data_01.dbf
   /db/abcp/DIR/abcp_data_02.dbf
$: sed 's#^\(/db/abcp/DIR/abcp\)\(_.*\.dbf\)$#/db/abct/DIR/abct\2#' file3 > file
$: cat file
/db/abct/DIR/abct_data_01.dbf
/db/abcp/DIR/abcp_data_01.dbf txt
   /db/abcp/DIR/abcp_data_02.dbf

smd-server

smd-server(1)						 Sync Mail Dir (smd) documentation					     smd-server(1)

NAME

       smd-server - sends diffs and mails to smd-client

SYNOPSIS

       smd-server [--exclude glob] [-v|--verbose] [-d|--dry-run]
	     [--get-mddiff-cmdline] [--stop-after-diff]
	     [--override-db dbf] [--dump-stdin tgt] endpoint mailboxes

DESCRIPTION

       smd-server needs to know a name (endpoint) for the client (that must not be used by others) and a list of mailboxes (directories).

       smd-server first calls mddiff(1), then prints on stdout the generated diff. It then accepts from stdin a small set of commands a client may
       issue to request a file (or parts of it, like the header).

       smd-server is in charge of committing the db file used by mddiff(1) in case the client communicates a successful sync.

OPTIONS

       -v --verbose
	      Increase program verbosity (printed on stderr)

       -d --dry-run
	      Do not perform any action for real

       -n --no-delete
	      Do not track deleted files

       --exclude glob
	      Exclude paths matching glob

       --override-db dbf
	      Use dbf as the db-file

       --get-mddiff-cmdline
	      Print the command line used for mddiff and then exist

       --stop-after-diff
	      Send the actions to the other endpoint and exit. If used in conjunction with --override-db, dbf is removed just before exiting

       --dump-stdin tgt
	      Dump standard input to tgt and exit

NOTES

       smd-server is a low level utility. You should use higher level tools like smd-pull(1) and smd-push(1)

SEE ALSO

       mddiff(1), smd-client(1), smd-pull(1), smd-push(1)
