Shell script to stop all running vagrant instances under current user.

vagrant_stop.sh

#!/bin/bash -e

### 1. Script globally checks for all vagrant instances running under the user executing the script.
### 2. Assigns the instance ID's of any running instance to the variable "instances".
### 3. Checks for whether the variable "instances" is an empty string.
### 4. If not an empty string, then run a for loop to print vagrant instance information and halts (stops) it.


vagrant_stop () {

instances=$(vagrant global-status --prune | grep running | awk '{ print $1}')

if [ -z "${instances}" ];
then
  echo -e "\nVagrant instances are not running. No instance to halt!\n"
else
  for instance in ${instances};
  do
    echo -e "\nVagrant instance state for:\t${instance}\n"
    vagrant status ${instance}
    echo -e "\nStopping Vagrant instance:\t${instance}\n"
    vagrant halt ${instance}
    echo -e "____________________________________________________________"
  done
fi
