Todo List in a Nut Shell

Update: Now just type todo to see your todo list. The old -s Option is still there. I also fixed a Bug which causes the marking more than one line to fail when you use the last line of your todo list as the last argument or rather specific when you use the n-1 last lines of n marked entries as arguments. Thanks to my friend sebastian who gave the crucial hint for fixing that issue.

Update: I fixed some bugs in the script. Entries which are marked as done are moved to the bottom of the $TODO_LIST_FILE. The Script checks if arguments to -u or -x or -m are valid integers and if these lines really exists in the $TODO_LIST_FILE. It should now be impossible to give line 23 as argument when such line does not exist. The Script will exit with exit status 1 if one of the arguments is not valid. This feature will give you more protection from destroying your todolist.
Some rather minor options; the -B Option (backup your todolist) and the -R (restore your todolist from backup); have been added.

Update: I spend a little time in the train to implement new features in the todo.sh Script.
1) With -m (modify) you are able to edit or correct entries. You need read and gawk
to get this working.
2) With -p you are clearing the todo list. All(!) Entries getting lost. And with -pp you even remove
the $TODO_LIST_FILE.

Update: The newest version does'nt need a new entry enclosed in "". I fixed this issue on weekends.

Update:
You also can unmark and mark more than one entry at a time. Just list them as arguments separated by spaces.

Hi girls and guys,

on weekend i have had a little bit time to clean up my github repository and work on new scripts. so i manged beginning one of my most usefull scripts.

When i had the idea i was writing my things i had to do in a simple textfile using the editor of my choice (vim). so i was wondering whether i could maintain a simple todo list on my machine without having firing up an editor every time. So i came up with the idea to write a small script using sed and grep which would accomplish this task.

Simply download the script or clone my github repository. I recommend putitng the script to /usr/local/bin and link the script to /usr/local/bin/todo.

And this is how it works: You simply add a new entry to your todo list by typing:

todo -a My new task

Since you don't have a file for your todo list yet you will be asked creating a new one. This is just my way of doing things, because i think that no actions should be taken without the user knowing whats going on.

More entries can be added the same way:

todo -a just an other task
todo -a oh no not again

You now have three open tasks in your todo list which can be seen by typing:

todo -s

1 new task --> [o]
2 just an other taks --> [o]
3 oh no not again --> [o]

if you have finished one task you can mark this particular task as being done using the line number and the -x option:

todo -x 2

You can reveal this by using the -s option again:

todo -s

1 new task --> [o]
2 just an other taks --> [x]
3 oh no not again --> [o]

--> [x] indicates for you that the task with line #2 has been marked as one you managed to finish.

You can inspect only those tasks which are open by using the -o option and those which you have marked as being done by using the -d option.

Lets say the task has come available again and you need to do this task again. You can readd this task to your open task by using the -u #N option, where the parameter #N is the number of the line you want to readd.

And finaly todo -r clears all (!) task you have marked as finished.

Although i will improve this script and will add more features it works pretty well in this early stage and i welcome you to comment and improve my work.

that's all folks

Testing and ranting openSUSE 12.1 RC1

Update: openSUSE 12.1 has now been stable since a while. Works perfect on my Thinkpad. Filed a Bugreport on systemd. To disable the tracker daemon use Alt+F2 and type gnome-session-properties. Here you can disable the tracker daemon.


Update: Filed a bug about high RAM consummation for 12.1. Will not upgrade to 12.1 on my main machine.

First things first SuSE 12.1 is still not ready and i just tested it out on my Desktop PC still having
a backup of my old 11.4 version. I am yet unsure whether i want to change or not. At least on my Main Thinkpad Machine i will still use the older 11.4.

There is a bug affecting Software changes and keeps the Yast-installer crashing if you use version 12.1 rc1. But as long as you keep going with the default installation everything else will go fine. In fact finally i don't have to manage my external encrypted devices setup after i finished the installation. This all goes fine in the current installation procedure.

Yast doesn't look much different from the previous versions but they changed it in the details. For example during the installation when showing how much GB are going to be installed they changed to 4 digits after the "," so you dont stare at 2,0 gb to install for like 2 minutes and you actually can see more details when it says: "2,0423 to install".

But there are some bugs in the packages. When you install a package you often
get a message like this:

"/usr/bin/desktop-database --defaults-list unknown option"

Also i found a couple of new Yast modules which are looking pretty interesting and you are able to add sax3, the reborn sax. Since Sax3 is still under development you shouldn't install it if your monitor settings are fine anyway. For example the Snappper module to create filesystem snapshots for ext4 and btrfs seems interesting but did not load correctly.

The first time i tried opensuse 12.1 rc1 i was confronted with the fact that they now have a lot of new stuff that has changed in 12.1. Well what was the reason for there is no .0 release any more? Right so people don't believe that there is a major change here.

Changing from sys-V-init to systemd is in fact a big change. And the best documentation i found about this is here . The startup of the computer is very fast. My pc boots up in notime now and so is the change to an other runlevel. But however this doesn't bother me since i usually do not reboot often or change runlevels. You do this mostly for maintenance reasons, right? However changing to systemd was not the best choice. In the description it says its backwarts compatible to sys-V-Init. Well its not. For one reason there is no shutdown -F any more. which forces the
check of your filesystem when you boot up next time in sys-V-init shutdown. I think this is not acceptable. A workaround for this would be setting the check interval to 1 with tune2fs like this:

tune2fs -c 1 /dev/sda1

and set it back to normal after rebooting like this:

tune2fs -c 60 /dev/sda1

For an other reason, this might be only affecting 12.1 RC1 switching from runlevel 5 to runlevel 1 will freeze the system at least if you are using gnome3 with proprietary driver like described at the bottom.

It still uses the patched Version of Grub1 which i am fine with since this is easier to administer.

Of course i installed gnome3 and was unhappy at first but than i discovered the nice gnome-shell extensions and i loved it. But gnome3 is much more RAM consuming than the 2.x one. With 2GB RAM and 2GB Swap it uses 60% out of 800 GB RAM and nearly 500 GB Swap.
You can install the package gnome2-look-and-feel to get the gnome2 look and feel back if you don't like gnome3 with gnome-shell.
However an other problem is that Windows don't size correctly so that you are leaving with guessing what "Toog" or "Men" could mean. And how do you change the icon theme? You have to install a tool that allows you to access the "Advanced Settings" And if you don't know that the menueditor is called alacrte its not possible to change the menu items by right klick like in gnome2. Also anyoing everytime you log in there is this message you have to clickaway multiple times for every device that gets mounted during start up. If you like me and have like 5 mounted devices this can get very annoying. And how do deactivate this tracker thing. i dont want the daemon to itch my hard drive all the time. Uninstalling it will also uninstall the whole gnome3-session. WTF!!! I am looking for a way to get this disabled on startup: All i know for now is how you can create autostart items by creating proper files in ~/.config/autostart/
and that you can disable the tracker dameon by using tracker-control -t all
Synapse program is much much better than the gnome-do program though and is called to live with the same shortcut.

I miss the Terminator Terminal which i used to monitor the system with tools like sar, htop, iotop and iftop and tail -f /var/log/messages.

An other thing which does not affect servers but does in fact the user is that it needs a little effort to get the nvidia propriatary driver running for gnome3. With the kind hint of zaitor from the irc channel #opensuse-gnome i was able to finally install it. asuming you already have downloaded the driver follow these steps will install the driver:


Nvidia driver is running

(1) Install gcc make and kernel sources and all dependecnies like this zypper ref && zypper in kernel-source make gcc

(2) change to runlevel 3 and execute the installer like this
./NVIDIA-Linux-(arch)-255.05.09.run. You will be asked whether a file in
disable-nouveau.conf in /etc/modprobe.d should be created. answer this with yes and leave the installer for now.

(3) Disable the noeveau using cat /etc/modprobe.d/disable-nouveau.conf >> /etc/modprobe.d/50-blacklist.conf

(4) in yast or with zypper uninstall the nouveau driver.

(5) in yast --> System --> Editor for /etc/sysconfig search for kms and change the value from yes to no.

(6) restart the system. init 1 and init 3 wont work with systemd since the old driver is still loaded

(7) change in runlevel 3 and execute the installer again like in (2) this time the installation should be finished without problems. Answer with yes when you are being asked whether /etc/X11/xorg.cong should be written for you.

(8) add the group video to the system user gdm and the user you want to use. In the case the usersname is geeko:
usermod -A video gmd && usermod -A video geeko

(9) change in runelvel 5
That's it. now you can use the better nvidia driver with better perfomence at 1% cpu load instead of 20% cpu load. Remember that you have to redo this procedure every time you get a kernel update.

That's it for today. ;)
