First of all welcome to this forum.
There was another, more important problem with your sed attempts and that was the greediness of sed, as ctsgnb pointed out. My post was related to that and made a point about anchoring the regex. It was perhaps primarily meant for ctsgnb, but it may be of use to you too, so I reckon it certainly is related to this thread and it is not off topic. Please also note that this is not "your" thread as the OP. A thread may be of use to you as the OP, to those who participate, to anyone who reads along and to those who use it as a reference or land there as the result of a query.

Further, it is not so much that sed treats + and {} as normal characters. It is that modern sed adheres to POSIX BRE (Basic Regular Expressions) and as such curly brackets need to be escaped, but + is not even supported. Only GNU sed has an extension that supports it as \+ .
If you wish to use ERE (Extended Regular Expressions) you can use GNU sed with the -r option and then + and {} can be used without the escape, since { and + are part of ERE.

nwbpset
NWBPSET(1) nwbpset NWBPSET(1)
NAME
nwbpset - Create a bindery property or set its value
SYNOPSIS
nwbpset [ -h ] [ -S server ] [ -U user name ] [ -P password | -n ] [ -C ]
DESCRIPTION
nwbpset Reads a property specification from the standard input and creates and sets the corresponding property. The format is determined by
the output of 'nwbpvalues -c'. nwbpset will hopefully become an important part of the bindery management suite of ncpfs, together with
'nwbpvalues -c'. See util/nwbpsecurity for an example.
As another example, look at the following command line:
nwbpvalues -t 1 -o supervisor -p user_defaults -c |
sed '2s/.*/ME/'|
sed '3s/.*/LOGIN_CONTROL/'|
nwbpset
With this command, the property user_defaults of the user object 'supervisor' is copied into the property login_control of the user object
'me'.
nwbpvalues -t 1 -o me -p login_control -c |
sed '9s/.*/ff/'|
nwbpset
This command disables the user object me.
Feel free to contribute other examples!
nwbpset looks up the file $HOME/.nwclient to find a file server, a user name and possibly a password. See nwclient(5) for more information.
Please note that the access permissions of $HOME/.nwclient MUST be 600 for security reasons.
OPTIONS
-h
-h is used to print out a short help text.
-S server
server is the name of the server you want to use.
-U user
user is the user name to use for login.
-P password
password is the password to use for login. If neither -n nor -P are given, and the user has no open connection to the server, nwbpset
prompts for a password.
-n
-n should be given if no password is required for the login.
-C
By default, passwords are converted to uppercase before they are sent to the server, because most servers require this. You can turn off
this conversion by -C.
