How to chroot from a Ubuntu LiveCD

For the sake of posterity, the following commands will allow you to login to an otherwise unbootable Linux install and run commands from the install on the hard drive: sudo fdisk -l sudo mount /dev/sda6 /mnt sudo mount –bind /dev /mnt/dev sudo mount –bind /proc /mnt/proc sudo mount –bind /sys /mnt/sys sudo chroot /mnt /bin/bash With thanks to this part of the Ubuntu wiki. For those are are interested, I managed to break my 64 bit install of Karmic 10.04 on my brand new Asus laptop by activating the proprietary (Nvidia) drivers when the install offered. After Usplash I see now is a black screen, however the system is working. Installing the version from Nvidia’s website did not help. Deleting xorg.conf (and forcing the system to use the fall-back VESA driver) worked.

July 2010 Laptop Comparison

I often get asked “what laptop should I buy?”. This really comes down to your requirements.

Neat things with find, LAME and sed in Bash

Just want to¬†chronicle¬†l some really neat, time saving tricks I’ve picked up today for handling files in bash. The first, how to use the find command:  find -type f -iname "*.txt" Easy enough, right? Let’s use find and cp to back up a bunch of text files:  find . -name "*.txt" -execdir cp {} a_copy.txt  \; NOTE: the above assumes that there is only one text file in each directory, and will create a file in the same directory being a copy of whatever file it is that the find command returns. Let’s string find to sed, and use sed to replace all instances of “.ogg” to “.mp3” within a collection of text files:  find . -name "*.txt" -exec sed -i "s/.ogg/.mp3/g" ‘{}’ \; Let’s also use find and LAME together to convert a batch of wav files to mp3 files (I recommend you run the following from within a screen session):   find -type f -name "*.wav" -execdir /usr/bin/lame -V3 {} \; NOTE: The above will create mp3 files
