If you look at the examples closely, along with the explanation durden_tyler provided, you'll see what the code does.
Code:
$ echo 23344 | sed 's/2\([0-2][0-9]\)\([0-5][0-9]\)/#\1#\2#/g'
23344
$ echo 22344 | sed 's/2\([0-2][0-9]\)\([0-5][0-9]\)/#\1#\2#/g'
#23#44#
$ echo 72344 | sed 's/2\([0-2][0-9]\)\([0-5][0-9]\)/#\1#\2#/g'
72344

Code:
$ echo 22364 | sed 's/2\([0-2][0-9]\)\([0-5][0-9]\)/#\1#\2#/g'
22364
$ echo 22354 | sed 's/2\([0-2][0-9]\)\([0-5][0-9]\)/#\1#\2#/g'
#23#54#
$ echo 12354 | sed 's/2\([0-2][0-9]\)\([0-5][0-9]\)/#\1#\2#/g'
12354

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 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. AUTHORS
nwbpset was written by Volker Lendecke. See the Changes file of ncpfs for other contributors. nwbpset 8/7/1996 NWBPSET(1)
