I dont know... normally people would redirect in a file somewhere else (You dont have just that filesystem do you?) where space isnt an issue then overwrite...
Im saying that because most editing utilities would create a temorary file in /tmp or /var/tmp... if you are that stuck you will have to do some cleaning up first then

NAME
dncopynodes - copy a list of nodes from a remote DEC system SYNOPSIS
dncopynodes <nodename> [ldif-dn] DESCRIPTION
This program will generate a decnet.conf file by contacting a remote DECnet host (running VMS or RSX-11 probably) and doing the equivalent of "NCP COPY KNOWN NODES". The resulting file can be copied over the existing decnet.conf file if you like. You do need a fully-functioning DECnet system before using this command but you don't need any nodes other than the executor defined in decnet.conf. dncopynodes will copy the executor information already there into the new file. The program copies its output to standard output. It is strongly recommended that you review it before replacing an existing /etc/dec- net.conf file. The node name can also be a node address if you don't have any nodes defined in your existing decnet.conf. DO NOT attempt to redirect the output of dncopynodes directly into /etc/decnet.conf. It will fail and destroy your existing configuration file! Send it to a temporary file and then copy it (see EXAMPLES) dncopynodes can also create an LDIF file suitable for importing into an LDAP database. With dnprogs 2.48 or later, DECnet programs can quiry this for node address information. EXAMPLE
# dncopynodes 3.34 > /tmp/decnet.conf # dncopynodes 3.34 dc=example,dc=com > /tmp/decnet.ldif # mv /tmp/decnet.conf /etc SEE ALSO
