You could use something like that: file -F' ' --mime-type * | awk '$2 ~ /text\/plain/{print $1}' | xargs chmod 644 This changes all permissions to 644 if a file has the mime-type text/plain. Just replace the part in the awk body to whatever mime-type you wish. See /etc/mime.types for all available ones. Explanation: The -F' ' flag causes file to use a ...

It is always possible to delete EVERYTHING, start from scratch, and install a new Operating System (in fact this tends to be the easiest way to install an OS). This holds for Linux, Mac OS, and Windows. When you boot from the Windows Live Media (e.g. installation DVD) and choose an option similar to "Erase disk and install", it will delete EVERRYTHING on ...

Just click on the Windows drive (probably labelled WIN or WINDOWS or whatever) and it will be automatically mounted, if possible.

As can be seen from What is the CVE-2014-6271 bash vulnerability (Shellshock) and how do I fix it?, the patched version for 14.04 is 4.3-7ubuntu1.4, whereas the 14.04.1 image contains 4.3-6ubuntu1. Once released, an ISO is never changed. So an installation image will contain the fix when 14.04.2 is released.

The driver iwlwifi usually creates an interface wlan0, not eth1.

You're not running 14.04 as you indicated, but you're actually running 12.04. All the output you show support this scenario. Therefore, the proposed upgrade to 12.10 is valid. However, I recommend not to run this. Once on 12.10 you'll have to go through the long process of 12.10 → 13.04 → 13.10 → 14.04 to reach a supported release. LTS → LTS+1 upgrade path ...

The nginx package is just a metapackage, and points to the nginx flavors. Because apt-get, apt, and dpkg are not as smart as users assume it will be, removing the nginx package does not remove the actual nginx binaries and common files. Run the following to remove all flavors of NGINX from the system. This will catch at least one installed one, and the ...

I believe your CATALINA_BASE is incorrect it runs out of the /var/lib/tomcat7 directory and CATALINA_HOME is proper in regards to how you have declared the variable. Add CATALINA_HOME and CATALINA_BASE to /etc/default/tomcat7 along with JAVA_HOME and JRE_HOME. That executable notifies the tomcat servlet of how the environment is set upon start up of the ...

OK, answering my own question. Since I now have an Acer Chromebook CB5-311-T5G2 with ARM processor, I can now answer this question. The repositories are quite extensive.

Things I've noticed from the boot chart: The bottleneck seems to be disk utilisation. You may have a slow hard disk. ureadahead is taking a long time to run while waiting for I/O. This indicates hard disk speed is a factor.

Many live CD images are actually hybrid CD/USB images, so they can be copied directly to either a CD or USB drive with dd and will work either way. This is true of all Ubuntu and Debian official live CD images over the last few years, and may be true of other distros. dd if=cdimage.iso of=/dev/xxx Where /dev/xxx is the USB drive. In cases where that ...
