scarolan / Vagrant_SSH_Shortcuts
Last active December 18, 2015 11:29
"vlist" and "vssh" commands for working with Vagrant virtual machines. Drop these in your .bashrc. vlist creates a list of all your running VMs. vssh loops through all your VMs, and attempts to run commands on each of them.
# vlist generates a list of running Vagrant VMs
vlist ()
{
vagrant status | awk '/running/{ print $1 }'
}
# vssh runs your command(s) on all VMs. Enclose in quotes to run multiple commands.
vssh ()
{
[ $# -ne 1 ] && (echo "Usage: vssh command"; return 1)

scarolan / AWS_Unixify_Windows
Last active June 7, 2018 15:02
This gist will create a new user with Administrator rights on a Windows server AWS instance, install Cygwin and SSHD, and open port 22 so that you can access the machine using SSH. This makes using Windows *much* more tolerable for the Unix administrator. Simply use the script below in your "User Data" field when deploying a new instance. The <p…
<powershell>
# First we add our administrative user, replace username and password with your own
$computer=$env:ComputerName
$user="username" ## Change this!
$password='password' ## And change this too!
$objOu = [ADSI]"WinNT://$computer"
$objGroup = [ADSI]"WinNT://$computer/Administrators,group"
$objUser = $objOU.Create("User", $user)
$objUser.setpassword($password)

Grabs image thumbnails from Flickr's API, then uses @heptal's most excellent "image" function to convert them into images in your terminal. If you want to search Flickr for multiple tags simply enclose them in quotes. ImageMagick and Python are required to use this.
