Access klipper clipboard on CLI under KDE4

› Code Snippets › Access klipper clipboard on CLI under KDE4

Here’s a little script you can save in your path and do things like

# paste current clipboard into file
clipboard > "some_file"
# copy some file into clipboard
cat "some_file" | clipboard

Actually I find it rather useful so I thought I will have to share it.

Since KDE4 D-BUS is used throughout KDE and thus in Klipper as well. IMO they should really rework the output of dbus-send or add some more flags (what about --quiet). Well that’s the reason why the script below is somewhat long. But nothing a little bit of bash+awk magic couldn’t cope with:

#!/bin/bash
 
# check for stdin
#   since we don't want to wait endlessly we set a timeout
#   a pity `read` only supports seconds and no fractions...
read -t 1 stdin
if [[ "$stdin" != "" ]]; then
  # get the rest of stdin
  stdin=$stdin$(cat)
  # oh, nice - user input! we set that as current
  # clipboard content
  dbus-send --type=method_call --dest=org.kde.klipper \
    /klipper org.kde.klipper.klipper.setClipboardContents \
    string:"$stdin"
  exit
fi
 
# if we reach this point no user input was given and we
#   print out the current contents of the clipboard
# note: I hate the output of dbus, dcop was much easier in that regard!
dbus-send --print-reply --dest=org.kde.klipper /klipper \
    org.kde.klipper.klipper.getClipboardContents | awk '
      BEGIN { output = ""; }
      {
        if ( NR > 1 ) {
          output = output $0 "\n";
        }
      }
      END {
        print substr(output, 12, length(output) - 13);
      }'

As usually, save the file (attached below) in your $PATH and make it executable.

PS: Thanks to Martin Vidner for his article on D-BUS btw. - it gave me the proper dbus commands.

This is awesome. I extended Thu, 05/06/2010 - 10:09 — Morten Slott Hansen (not verified)

This is awesome. I extended this with xmlcopyeditor and KDE4 hotkeys to have a quick way to get the clipboard content into an XML editor.

I created a script called xmlCopyEditor_readClipboard.sh

#!/bin/sh
/home/msh/bin/clipboard.sh > /tmp/clipboard.txt
/usr/bin/xmlcopyeditor /tmp/clipboard.txt

And attached it to a hotkey combination meta + shift + x

This has made my life so much better - hope others can find this usefull!

Hi, interesting post really. Tue, 10/20/2009 - 14:58 — Joetke (not verified)

Hi, interesting post really. But I wonder whether KDE 4 is mandatory because when I run your script I got this response: Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.kde.klipper was not provided by any .service files Regards.

Yes, this version is for KDE Thu, 10/22/2009 - 00:44 — Milian Wolff

Yes, this version is for KDE 4. I once had a KDE 3 version, but it looks like I lost it. It was much easier though, you’ll just have to exchange the DBUS stuff with the good old DCOP from KDE 3.

Thanks, it works flawlessly. Thu, 11/05/2009 - 14:38 — joetke (not verified)

Thanks, it works flawlessly. Regards from Strasbourg, France.

I have just found the answer Wed, 08/12/2009 - 01:21 — Anonymous (not verified)

I have just found the answer to my question. The trick is not to use “dbus-send”. It works with qdbus org.kde.klipper /klipper getClipboardHistoryItem 0 qdbus org.kde.klipper /klipper getClipboardHistoryItem 1 qdbus org.kde.klipper /klipper getClipboardHistoryItem 2

Is there some way to access Tue, 08/11/2009 - 22:23 — Anonymous (not verified)

Is there some way to access the klipper history from the command line?

Just look for yourself: run Wed, 08/12/2009 - 01:09 — Milian Wolff

Just look for yourself:

run qdbusviewer
go to org.kde.klipper
go to klipper/org.kde.klipper.klipper
pick any *history* method you’d like

For inspiration on how to use those stuff in bash see my script above.

AWESOME! I was sick of Thu, 07/30/2009 - 02:31 — Sam Tresler (not verified)

AWESOME! I was sick of ctl-shift-V’ing 40 lines at a time so I googled and found this. Precisely what I was looking for, thank you.

Here’s a little script you Thu, 11/20/2008 - 20:59 — Antonio (not verified)

Here’s a little script you can save in your path and do things like

cat “some_file” > clipboard

Of course, it destroyed the “clipboard” file :-)

Greetings from Spain!

P.S. I suppose it’s

  cat "some_file" | clipboard

Thanks, fixed. Wed, 11/26/2008 - 18:42 — Milian Wolff

Thanks, fixed.
