I recently discovered apt shell (aptsh), a psuedo shell which gives users of distributions which use apt for package management quick access to the functionality of apt-get. You should find aptsh in the repositories of Debian based distros. Once installed, you can launch 'aptsh' as root from the command prompt (i.e. 'sudo aptsh'). One of the drawbacks of installing software from the terminal is that sometimes you don't know the exact name of the package you want to install. From the aptsh> prompt, 'ls' plus a search string will show all the packages that have that string in their names. You can type 'install' plus a partial package name and use TAB completion to finish the instruction. The function of the 'update' and 'upgrade' commands are self explanatory, unfortunately, you can't string them together on the same line like you can in bash: sudo apt-get update && sudo apt-get -y safe-upgrade Instead, you use the backtick [ ` ] key to put aptsh into queue mode. In queue mode, you can enter commands one by one to be launched in sequence at a later time. To bring your system up to date, you could run: aptsh> ` * aptsh> update * aptsh> upgrade * aptsh> ` aptsh> queue-commit-say yes Backtick toggles queue entry, and queue-commit runs the queue. “queue-commit-say y” tells aptsh to answer in the affirmative to any queries from the commands executed in the queue in much the same way “apt-get -y safe-upgrade” confirms software updates without user interaction. Apt shell is capable of other apt related tasks, but I think I've covered the most useful ones. The trouble with running aptsh is that unless you start it in a terminal with the computer and leave it running all day (as opposed to opening it as a new shell within you terminal every time you want to update or install), despite the convienience of package name search and TAB completion, it really won't save you any keystrokes. With that in mind, I started looking for ways to have the apt shell available at a keystroke (we will leave the wisdom of leaving a shell open with a subset of root privileges for another day). I had guake installed, but rarely used it because I usually have multiple terminal tabs open since I am logged into my server remotely. [Actually, I had forgotten guake supports tabbed terminals quite well. You can open a new tab with <Shift><Ctrl>T and switch between terminal tabs by <Ctrl><PgUp> and <Ctrl><PgDn> or clicking buttons that appear at the bottom of the guake window. I had how, forgotten this until doing further research on this story. Since this revelation ruins my story, we will forget about tabbed terminal support in guake and not mention it again.] I am also going to assume everyone is familiar with guake. If not, suffice it to say guake is a terminal that pops down in the top third of the screen when you hit a hotkey, <F12> being the default. It returns to the background when you press <F12> again or click the lower part of the desktop. It is patterned after the command shell in the game Quake that let you input diagnostic and cheat codes, hence

Dann makes a welcome return with his podcast, blogg and video entry over at http://www.linuxintheshell.org/2012/11/06/episode-017-split/ The split command is used to split up a file into smaller files. For example, if you need to transfer a 3GB file but are restricted in storage space of the transfer to 500 MB you can split the 3GB file up into about 7 smaller files each 500MB or less in size. Once the files are transferred restoring them is done using the cat command and directing the output of each file back into the master file: split -b500M some3GBfile Please visit his site for more splitty goodness

Kit Description My Backpack My Backpack - note the HPR Badge - this is the bag I take to work every day. My Acer Aspire netbook This is a refurbed type unit I got from the Acer Direct. My Kindle 2 This kindle was a birthday present from Rachel, last year. She knows me so well :)Its loaded with a load of ebooks from the great folks at O'reilly.The case for this was from Tesco My Car-pod ipod When I upgraded cars the biggest disappointment for me was that going from a Kia Cee'd , where I could plug in USB keys with pod-casts on - I now no longer had a USB port in my SEAT. Rachel bought this for me from CEX. I've replaced the firmware with rockbox. My newest iPod My newest iPod - this used to belong to my Rachel, but the screen has started to go - She looked at getting it repaired - pricey as it is out of the warranty period - so she got herself a new one (cue a long process of me transferring her songs to the new iPod :() and I acquired her old one. I have replaced the Apple firmware with rockbox, and it works great under Linux. My 2GB USB Key This key contains nothing (at the moment) apart from a design for a leaving cake (Keep calm and Google it) and a file called ldlinux.sys, left over from the previous contents.

This is another one of my How I Did It Podcasts (or How I Done It if you rather) where my goal is to pass along the things I learn as a common Linux user administering my home computers and network, and engaging in the types of software tinkering that appeals to our sort of enthusiast. I'd been thinking for a while about replacing the small computer on my dinner table. I had been using an old HP TC1000, one of the original active stylus Windows tablets, of course now upgraded to Linux. With the snap in keyboard, it had a form factor similar to a netbook, with the advantage that all the vulnerable components were behind the LCD, up off the table and away from spills. It had served my purpose of staying connected to IRC during mealtimes, and occasional streaming of live casts, but I wanted more. I wanted to be able to join into Mumble while preparing meals, I wanted to be able to load any website I wanted without lockups, and I wanted to stream video content and watch DVDs. I was concerned that putting a laptop on the table was an invitation to have any spilled beverage sucked right into the air intakes, and I never even considered a desktop system in the dining room until I saw a refurbished Dell Inspiron 745 on GearXS.com (I wouldn't normally plug a specific vendor, but now GearXS is putting Ubuntu on all it's used corporate castoff systems). This Dell had the form factor that is ubiquitous in point-of-sale, a vertical skeleton frame with a micro system case on one side and a 17” LCD on the other, placing all the electronics several inches above the surface on which it is placed. I even found a turntable intended for small TVs that lets me smoothly rotate the monitor to either at my place on the table or back towards the kitchen where I am cooking. I already had a sealed membrane keyboard with an integrated pointer and wireless-N USB dongle to complete the package. Shipped, my “new” dual core 2.8Ghz Pentium D system with 80Gb hard drive and Intel graphics was under $150. [The turntable was $20 and an upgrade from 1Gb to 4Gb of used DDR2 was $30, but both were worth it.] Since the box shipped with Ubuntu, I thought installing the distro of my choice would be of no consequence, and that is where my tale begins. I'm going to start my story towards the end, as it is the most important part. After the installation of four Linux distros in as many days (counting the Ubuntu 10.04 LTS the box shipped with, a partial installation of SolusOS 2r5, Fuduntu and finally Lubuntu 12.04), I discovered I couldn't boot due to Grub corruption (machine POSTed, but where I should have seen Grub, I got a blank screen with a cursor in the upper left corner). A. I thought I would do a total disk wipe and start over, but DBAN from the UBCD for Windows said it wasn't able to write to the drive (never seen that before) B. Started downloading the latest RescaTux ISO. Meanwhile, I found an article that told me I could repair Grub with a Ubuntu CD https://ubuntunigeria.wordpress.com/2010/09/02/how-to-restore-grub2-using-an-ubuntu-live-cd-or-thumb-drive/ , so I tried booting from the Lubuntu 12.04 CD (using the boot device selector built into the hardware). Same black screen, preceded by a message that the boot device I had selected was not present. Same thing with the Fuduntu DVD that had worked the day before. With the exception of UBCD, I couldn't get a live CD to boot. C. Now having downloaded the RescaTux ISO, and suspecting a problem with the optical drive, I used Unetbootin to make a RescaTux bootable thumb drive. RescaTux ( http://download2.berlios.de/rescatux/rescatux_cdrom_usb_hybrid_i386_486-amd64_0.30b7_sg2d.iso ) has a pre-boot menu that let's you choose between 32 and 64 bit images, but that was as far as I got, nothing happened when I made my selection.

It took 14 months longer than intended to get this episode done! To make up for it, I've unintentionally ended up with enough time of me talking to almost make up a minimal-useful-sized episode every month while everyone's been waiting. Today's episode of "Thoughtkindness" consists of: Me begging for forgiveness for disappearing for a year. An update on "bunnies", my linux laptop from Ohava Computers Over an hour of my attempt to collect and explain why we need to make media on the internet more "freetarded" After revealing what ticked me off and made me start on this episode, I launch into a short technical and historical talk about the handful of audio and video files that matter on the web today. (Opus, Ogg Vorbis, WebM, MP3, Flash Video, MP4, and a few others). Following this, I explain why I think the legally-free media formats are so important, and much more useful than most people seem to recognize, why I think we need to be paying more attention to audio than video, and what needs to happen to make legally-free media ubiquitous. I conclude by once again begging for attention and foolishly publically announcing that I want to try to develop some software and invite everyone to pester me for it as well as for future audio shows. Maybe I won't be allowed to procrastinate for another year before producing more this time. Let me know if this is helpful or at least entertaining... Note: an Opus version of this episode will be available at http://hpr.dogphilosophy.net for either online listening in Firefox 15 or later, or downloading for listening in VLC or other Opus-supporting applications.

Recovery of an (en)crypted home directory in a 'buntu based system by 5150 This is going to be the archetypal “How I Did It” episode because if fulfills the criterion of dealing with an issue most listeners will most likely never have to resolve, but might be invaluable to those few who some day encounter the same problem, how to recover an encrypted home folder on an Ubuntu system. I enabled home folder encryption on installation of a Linux Mint 8 system some years back and it never gave me trouble until the day that it did. Suddenly, my login would be accepted, but then I would come right back to GDM. Finally I dropped into a text console to try to recover the contents of my home folder, and instead found two files, Access-Your-Private-Data.desktop and README.txt . README.txt explained that I had arrived in my current predicament because my user login and password for some reason were no longer decrypting my home folder (Ubuntu home folder encryption is tied to your login, no additional password is required). Honestly, until I lost access to my files, I 'd forgotten that I'd opted for encryption. I found two articles that described similar methods of recovery. I'd tried that following their instructions and failed, probably because I was mixing and matching what seemed to be the easiest steps to implement from the two articles. When I took another look at the material weeks later, I discovered I missed a link in the comments that led me to an improved method added at Ubuntu 11.04 that saves several steps: http://blog.dustinkirkland.com/2011/04/introducing-ecryptfs-recover-private.html Boot to an Ubuntu distribution CD (11.04 or later) Create a mount point and mount the hard drive. Of course, if you configured you drive(s) with multiple data partitions (root, /home, etc) you would have to mount each separately to recover all the contents of your drive, but you only have to worry about decrypting your home directory. If you use LVM, and your home directory spans several physical drives or logical partitions, I suspect things could get interesting. $sudo mkdir /media/myhd /media is owned by root, so modifying it requires elevation You need to confirm how your hardrive is registered with the OS. I just ran Disk Utility and confirmed that my hard drive was parked at /dev/sda, that meant that my single data partition would be at /dev/sda1 $sudo mount /dev/sda1 /media/myhd Do a list on /media/myhd to confirm the drive is mounted $ls /media/myhd The new recovery command eliminates the need to re-create your old user $sudo ecryptfs-recover-private (yes, ecrypt not encrypt) You will have to wait a few minutes while the OS searches your hard drive for encrypted folders When a folder is found, you will see INFO: Found [/media/myhd/home/.ecryptfs/username/.Private]. Try to recover this directory? [Y/n] Respond “Y” You will be prompted for you old password You should see a message saying your data was mounted read only at /tmp/ecryptfs.{SomeStringOfCharacters} I missed the mount point at first, I was look for my files in /media/myhd/home/myusername If you try to list the files in /tmp/ecryptfs.{SomeStringOfCharacters}, you will get a “Permission Denied” error. This because your old user owns these files, not your distribution CD login [You will probably want to copy “/tmp/ecryptfs.{SomeStringOfCharacters}” into your terminal buffer as you will need to reference it in commands.
