Ubuntu – get IBUS-Warning on running the sudo gedit command

You cannot use !! in a shell script, as you cannot access the parent shell in a child shell. Though I recommend using sudo !!, if you really want to make a BASH script, you would have to use .bash_history, like so:

#!/bin/bash
sudo `cat $HOME/.bash_history | tail -n1`

It is definitely NOT a perfect solution, but it should do the trick. If you are using ZSH, this will not work, as ZSH does not output to .bash_history (of my knowledge). UPDATE: Here is a version that should work with ZSH:

#!/usr/bin/zsh
. $HOME/.zshrc
sudo `cat \`readlink -f $HISTFILE\` | tail -n1`

Hope this helps!

If you don't understand the script, it simply runs the last command entered in BASH with sudo.

This plugin is written for Python 2, but since gedit 3.8, only Python 3 plugins are supported. So some small changes are required.

1. Modify the installer (gedit-markdown.sh) to install the python3 markdown module:

   This is a patch that you can apply on the existing file (or you can just copy the full modified version available here):

2. Run ./gedit-markdown.sh install

   You should see python 3.4 instead of 2.7:

   ############################################################
   ##
   ## Installation of gedit-markdown
   ##
   ############################################################
   
   ## First step: check dependencies
   
   - gedit: 3.10.4
   - Python: 3.4
   
   [...]
   

3. Change the plugin loader to python3

   Replace /home/aarold/.local/share/gedit/plugins/markdown-preview.plugin with:

   [Plugin]
   Loader=python3
   Module=markdown-preview
   IAge=3
   Name=Markdown Preview
   Name[fr]=Aperçu Markdown
   Description=Show the HTML version of the Markdown text you're editing
   Description[fr]=Affiche l'aperçu en HTML du document Markdown en cours d'édition
   Authors=Michele Campeotto <micampe@micampe.it>\nJean-Philippe Fleury <contact@jpfleury.net>
   Copyright=Copyright © 2005, 2006 Michele Campeotto\nCopyright © 2009, 2011-2012 Jean-Philippe Fleury
   Website=http://www.jpfleury.net/logiciels/gedit-markdown.php
   

4. Convert /home/aarold/.local/share/gedit/plugins/markdown-preview/__init__.py to python3:

   Run:

   2to3 -w /home/aarold/.local/share/gedit/plugins/markdown-preview/__init__.py
   

   Finally open this file and edit line 86 (remove the binary mode, "wb" -> "w"):

   with open(confFile, "w") as confFile:
   

5. Activate the plugin in Gedit as you did.
