NFDUMP(8) System Manager's Manual NFDUMP(8)
NAME
nfdump, nfload - notesfile dump/load programs
SYNOPSIS
nfdump notesfile
nfload [ -Ddirectory ] notesfile
DESCRIPTION
Nfdump and nfload are used to convert notesfile data base formats.
Nfdump converts the specified notesfile to a portable ASCII format and writes it to standard output. Some diagnostics are produced on
stderr. Nfdump can be run by any user; access to a particular notesfile is governed by that notesfile's access list.
Nfload is used on the output from nfdump to create a new notesfile. The -D option specifies an alternate base directory for the notesfile.
If unspecified, this defaults to ``/usr/spool/notes''. Nfload reads standard input for the ASCII representation of the notesfile.
Typical use of these two programs occurs when converting an existing notesfile data base to a new format. The nfdump program should be
compiled with the older structure definitions while nfload is compiled with the newer structures. The data base can then be converted with
a shell script of the following nature:
mkdir .OLD
mv * .OLD
for i in `ls .OLD`
do
echo $i start
nfdump $i | nfload -D/usr/spool/newnotes $i
done
echo $i done
echo ALL DONE
rm -rf .OLD
This assumes that the old data base is in ``/usr/spool/notes'' and the new data base is to be placed in ``/usr/spool/newnotes''. After the
conversion is complete, one can move the old data base from ``/usr/spool/notes'' to ``/usr/spool/oldformat'' and the new data base from
``/usr/spool/newnotes'' to ``/usr/spool/notes''.
