The dot is a special character in regexes, a wildcard.
man regex:
Quote:
An atom is a regular expression enclosed in "()" (matching a match for the regular expression), an empty set of "()" (matching the null string)(!), a bracket expression
(see below), '.' (matching any single character), '^' (matching the null string at the beginning of a line), '$' (matching the null string at the end of a line), a '\'
followed by one of the characters "^.[$()|*+?{\" (matching that character taken as an ordinary character), a '\' followed by any other character(!) (matching that
character taken as an ordinary character, as if the '\' had not been present(!)), or a single character with no other significance (matching that character). A '{'
followed by a character other than a digit is an ordinary character, not the beginning of a bound(!). It is illegal to end an RE with '\'.
It also matches dots like in your example 2, but would also work on
-txt-doc. To explicitly match a dot in the text, it has to be escaped innregexes to suppress its special meaning.

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.
