Sometimes distribution providers (such as UCS) only give you VirtualBox .ova files to test their software. Here is how you can easily and non-interactively import a .ova file into a .box for use with Vagrant.

$ VBoxManage import ./UCS-Virtualbox-Demo-Image.ova --vsys 0 --eula accept                                                                                                                                   0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% Interpreting /home/crohr/dev/ucs/./UCS-Virtualbox-Demo-Image.ova...                                                                                                                       OK.                                                                                                                                                                                                         Disks:  vmdisk1 53687091200     -1      http://www.vmware.com/interfaces/specifications/vmdk.html#streamOptimized       UCS-Demo-Image-virtualbox-disk1.vmdk    -1      -1                                 ... 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% Successfully imported the appliance.                          

Then list your VMs to find the VM ID:

$ VBoxManage list vms "UCS 4.1" {acef4c0a-35be-4640-a214-be135417f04d}

You can now package that VM as a Vagrant box:

$ vagrant package --base acef4c0a-35be-4640-a214-be135417f04d --output UCS.box                                                                                                                             ==> acef4c0a-35be-4640-a214-be135417f04d: Exporting VM...                                                                                                                                                 ==> acef4c0a-35be-4640-a214-be135417f04d: Compressing package to: /home/crohr/dev/ucs/UCS.box                                                                                          

And add it to the list of your local Vagrant boxes:

$ vagrant box add UCS.box --name UCS

Finally, you can create a Vagrantfile to use this box:

Vagrant.configure("2") do |config|  config.vm.box = "UCS"  # ... end

And vagrant up!

use atom editor regex find and replace along with backref operator to do some complex ops 

Example : single quoted string (‘this is a string’) to double quoted string in the code.

Search regex for : 

\'((\w|\.|\/)*)\' 

replace it by 

To set rebase strategy for git pull 

file ~/.gitconfig

ssh command :: ssh -D 8080 -f -C -q -N myuser@remote_ssh_server

-D 8080 : This does the dynamic stuff and makes it behave as a SOCKS server. -f : This will fork the process into the background after you type your password. -C : Turns on compression. -q : Quiet mode. Since this is just a tunnel we can make it quiet. -N : Tells it no commands will be sent. (the -f will complain if we don’t specify this)

Configure your socks proxy to 127.0.0.1 and port you have chosen here it is 8080.

Example - for firefox network setting

network.proxy.no_proxies_on : localhost, 127.0.0.1, 192.168.0.0/24, .yourcompany.com network.proxy.socks : 127.0.0.1 network.proxy.socks_port : 8080 network.proxy.socks.remote_dns : true network.proxy.socks_version : 5 network.proxy.type : 1

dconf write /org/gnome/shell/app-switcher/current-workspace-only 'true'

To erase it, going back to default settings:

Apps are re-usable modules of code which can be attached to any project.

python manage.py startapp <app_name>

This will create a app structure in project folder

Add this app under INSTALLED_APPS tuple in settings.py of project
