Greetings all. :)
I would like to use sed to join all non-blank lines together in a particular file. I was thinking I could do this by simply replacing the terminating, new-line character on every line which is not blank, but I must be missing something in my sed line:

I want to use SED to replace all new line characters of a file, I googled and found this one liner
sed '{:q;N;s/\n//g;t q}' infile
what do :q;N; and t q mean in this script? (6 Replies)
Can anyone explain the below sed oneliner?
sed -e ':a' -e '$q;N;11,$D;ba'
It works same as tail command.
I just want to know how it works.
Thanks

I have a data base of part numbers:
AAA Thing1
BBB Thing2
CCC Thing3
File one is a list of part numbers:
AAA234
BBB678
CCC2345
Is there a sed one-line that would compare a data base with and replace the part numbers so that the output looks like this?
AAA234 Thing1
BBB678 Thing2... (5 Replies)

Hi,
I have the following command.(Delete all trailing blank lines at the end of a file.)
sed -e :a -e '/^\n*$/{$d;N;ba' -e '}'
I don't understand the logic of this command and also I don't understand why -e is used.
Can you please let me know the logic of this command and why three -e... (5 Replies)

mdbus2
mdbus2(1) General Commands Manual mdbus2(1)NAME
mdbus2 - Mickey's DBus introspection and interaction utility
SYNOPSIS
mdbus2 [OPTIONS...] [ busname [ objectpath [ method [ params... ] ] ] ]
DESCRIPTION
The mdbus2 command is used to explore and interact with DBus services on your system bus and session bus. Called without any parameters, it
will show the available services on the selected bus. Given a service name, it will show the available objects exported by the service.
Given a service name and an object path, it will show the exposed methods, signals, and properties of that object.
There are two well-known message buses: the systemwide message bus (installed on many systems as the "messagebus" service) and the per-
user-login-session message bus (started each time a user logs in). The --system option directs mdbus2 to operate on the system bus rather
than the session bus.
mdbus2 has three modes: The introspection mode, the listening mode (-l), and the interactive mode (-i). The interactive mode features
readline command completion and history.
The message bus configuration may keep mdbus2 from seeing all messages, especially if you run it as a non-root user.
OPTIONS --show-anonymous
Include unique DBus names (:1.xyz) in the output.
--show-pids
Include PIDs in the output. (Only valid in introspection mode)
--listen
Start in listening mode.
--system
Use the system bus rather than the session bus.
--interactive
Start in interactive mode.
EXAMPLE
Here is an example of using mdbus2 to listen to all signals on the session bus.
mdbus2 -s -l
