====== Maustasten belegen ======

===== Linux Mint (bzw. Ubuntu) =====

https://help.ubuntu.com/community/ManyButtonsMouseHowto

  sudo apt-get install imwheel


Button **10** ist die Daumentaste.

/etc/X11/imwheel/startup.conf:
  IMWHEEL_START=1
  IMWHEEL_PARAMS='-b "0 0 0 0 0 0 10"'
 
  
~/.imwheelrc:
  ".*"  
  None,		ExtBt7,   Alt_L|F9

Und schließlich unter //Einstellungen / Tastatur / Tastenkombinationen / Fenster / Fenster verkleinern// \\
//Alt + F9// einstellen (sollte aber auch Default sein).


===== Arch Linux =====
xorg-xev, xbindkeys und xdotool installieren:
  pacman -S xbindkeys xdotool xorg-xev

mit //xev// Button Nummer herausfinden.

Maustasten mit xbindkeys auf Tastendrücke legen:
~./xbindkeysrc:
  # Button 10 sends ALT+F9
  "xdotool key alt+F9"
  b:10

xbindkeys automatisch beim Einloggen starten:
~/.xprofile:
  xbindkeys &

In Desktop-Einstellungen ALT-F9 auf gewünschte Funktion, z.B. //Fenster minimieren// setzen.


====== Mausgeschwindigkeit einstellen ======
Per 'xset'.
Z.B.:
''xset m 5/4 0''

Das ganze dann als Startup definieren,

#cat ~/.config/autostart/mouse.desktop
  [Desktop Entry]
  Name=Set mouse sensitivity
  Exec=xset m 5/4 0
  Type=Application
  Comment=Use xset to set mouse params
  Comment[en_US]=Use xset to set mouse params
  Comment[de_DE]=Benutzt xset um die Maus-Geschwindigkeit einzustellen

====== Floppy auf 720 kB formatieren (USB-Laufwerk) ======
Von https://unix.stackexchange.com/questions/219533/how-to-format-720k-fat-ie-ms-dos-floppy-on-linux-using-usb-floppy-drive
und https://fitzcarraldoblog.wordpress.com/2017/01/17/using-an-external-usb-3-5-inch-floppy-disk-drive-in-linux/

''
$ sudo ufiformat -f 720 -v /dev/xxx
''

Danach mit mkfs.msdos Filesystem erstellen oder per dd beschreiben.

''
$ sudo mkfs.msdos -I /dev/xxx

====== Git ======

  ====================================== Create a new branch =====================================================
  
  # Create and checkout branch                                        Bitbucket: Create the branch in Bitbucket
  git checkout -b <branch>
                                                                      # Fetch the new branch and check it out
  # Push (empty) branch to the remote repository                      git fetch
  git push -u origin <branch>                                         git checkout LSAS-0815_CoolFeature
   
  # Do the work: edit, add, ...
  
  # Commit the branch
  git commit -m "Insert commit message here"
  
  # Push branch to the remote repository
  # ***********************************************************
  # Note: From Pro Git book: "In general the way to get the best of both worlds is to rebase local changes 
  # you’ve made but haven’t shared yet before you push them in order to clean up your story, but never rebase 
  # anything you’ve pushed somewhere.
  #
  # => so better first commit locally until finished, then rebase and then push to origin.
  # ***********************************************************
  git push    # Specify upstream if not already done above: git push -u origin <branch>
  
  
  
  
  ====================================== Rebase ==================================================================
  
  # Update master copy
  git checkout master
  git pull
  
  # go to branch which should be merged to master and make sure that remote is equal with your copy
  git checkout <branch>
  git pull    # only if branch is already pushed to origin
  
  # Start rebase
  git rebase master
  
  # solve conflicts with an editor e.g foo.cxx has a conflict
  kate foo.cxx # remove conflict
  git add foo.cxx
  
  # continue rebasing
  git rebase --continue
  
  # if there are no other conflicts to solve, push your branch to remote otherwise solve conflicts
  git push --force
  
  
  ====================================== Merge the branch with master ============================================
  
  git checkout master                                                 Bitbucket: Create pull request
  git merge <branch>                                                  Bitbucket: Merge
  git push                                                            Bitbucket: Delete <branch>
