Ubuntu – How To Disable Sticky Edges via Command Line

If you want to access the actual file itself, just use your favorite text editor (I use emacs but you can use pluma of gedit or vimor whatever):

emacs ~/.bash_history

That is the default location if your history file. If you don't find anything there, you may have changed the history file's name. This is stored in the $HISTFILE variable, so print it out to check its current value:

echo $HISTFILE

If, instead of the file, you just want to see your history, you can run history as @minerz029 suggested. The history command with no options just prints the contents of your $HISTFILE followed by the commands executed in the current shell that have not yet been written to that file, with line numbers.

I have no idea why you would want to do this and I should warn you that it may well be complicated to get the shortcuts back. If this is really what you want to do, the commands below will disable all keyboard shortcuts. Both those set up through Unity's GUI and any you might have set up using ccsm

A. Disable the Unity keyindings

1. First make a backup of the current bindings so you can re-enable them later

   gsettings list-recursively org.gnome.desktop.wm.keybindings | 
      perl -pe 's/(.*)\s*(\[.*?\])\s*$/$1\t$2\n/' | 
       while IFS=$'\t' read -r key val; do echo -e "$key\t$val"; done > old_settings
   

   This will create a file called old_settings in the following format:

   schema key <TAB> value
   

   For example:

   org.gnome.desktop.wm.keybindings unmaximize <TAB> ['<Control><Super>Down']
   

2. Now disable the shortcuts

   gsettings list-recursively org.gnome.desktop.wm.keybindings | 
       perl -pe 's/(.*)\s*(\[.*?\])\s*$/$1\t$2\n/' | 
           while IFS=$'\t' read -r key val; do gsettings set $key ['']; done
   

   Explanation

   • gsettings list-recursively org.gnome.desktop.wm.keybindings : this lists all keybindings and their current values
   • perl -pe 's/(.*)\s*(\[.*?\])\s*$/$1\t$2\n/' : this simply adds a TAB character (\t) separating the value from the key. This step is needed to be able to read them properly in the next one.
   • while IFS=$'\t' read -r key val : go through each line and read the key into $k and its value into $val. $IFS=$'\t' means split on tabs so that the key and value are read correctly.
   • gsettings set $key [''] : this actually sets the value to blank, effectively disabling your shortcuts.

   Note that you may have to log out and log back in again for this to take effect.

3. Get (some of) your shortcuts back

   while IFS=$'\t' read -r key val; do 
       gsettings set "$key" "$val"
   done < old_settings 
   

   WARNING: This will probably not work for all settings since some of them seem to have an extra parameter @as in the key name and I don't know how to deal with that one. As I said, this is all not a very good idea.

B. Disable your custom shortcuts set in ccsm

gsettings set org.gnome.settings-daemon.plugins.media-keys active false

This time, getting them back is easy. All you need to do is run

gsettings set org.gnome.settings-daemon.plugins.media-keys active true
