By placing the close square bracket immediately following the open character class, it is not interpreted as the end of the character class.

Using the '\'' construct you can "insert" a single quote into the class.

I don't know if I picked up all of the specials that you wish to remove, but you should be able to add what ever I missed.
I see an escaped t in your sed command. That tells me you're using a sed that supports more than mine does (e.g., symbols for tabs, newlines, etc. plus octal and hex, if it's the GNU version).

My shell with my sed won't let me escape a single quote if I'm also using single quotes to enclose my sed command sequence.

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 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)
