Quick Picks

What are "Quick Picks"?
I noticed over time, that some of the commands and tasks are always repeating themselves. I usually create a "HowTos" over most of the tasks or projects I do, but sometimes there just very trivial tasks, where a big story about it would be total overkill. So in this document I am gonna start listing all the little pain tasks, that will always keep on coming back and I wish I only have a quick pick to cut and paste them in order to use them without looking them up again.

 

1. Set your timezone (Debian -  10/10/2015)

Command:  dpkg-reconfigure tzdata

Link:  https://wiki.debian.org/TimeZoneChanges

 

 2. Reset a User Account so it will not expire again and the user needs to change there password.  (Debian -  10/10/2015)

Command:  chage

root@lostmyname:~# chage -l dave
Last password change                                    : Oct 05, 2015
Password expires                                        : Jan 03, 2016

3. Converting your DVD movies into .avi files  (Mint 17 - 10/12/2015)

Commands:

ln -s /dev/sr0 /dev/ dvd   # create a link from your device, so it will be called "/dev/dvd" and points to "/dev/sr0"

mplayer dvd://1 -v -dumpstream -dumpfile dump.vob  #  use the mplayer utility to get all *.vob (Video Object File) into one continuous file.


mencoder -ovc xvid -oac mp3lame  -xvidencopts fixed_quant=4 -lameopts cbr:br=192:aq=1  -aid 128 -vf crop=720:352:0:62,yadif -lameopts vol=3  -o newname.avi dump.vob -nosub   # using memcoder convert your video object file into an .avi file. 

Note:  I used the above to convert en-us DVD's to *.avi, because my european DVD drives complain about the region-code, Meaning the DVD encoding lets you only watch EN-US DVD on US sold DVD drives.  A dumm system if you ask me because everybody wants to be global these days....  Anyway this is a good way to get around it and you can even watch your converted movie on your Android devices.

 

4. Getting a glance from your system using "glances".  (Debian/CentOS - 23.10.2015)
