#Transitions an issue
#Find the transition id by going to your instance of jira and right clicking on the button you use to transition
# for example 'In Progress'. Copy the link and paste somewhere. You should get something like the below:
#
# https://localhost:8080/jira/secure/WorkflowUIDispatcher.jspa?id=49385&action=721&atl_token=BLAH-BLAH-BLAH-BLAH|som83hex9494maybe9394|lin
#
#Use the 'action=' value above in the query link. In the above example its 721  
#Note that at the end of the URL you have `/transitions`
curl -D- -u uname:pass -X PUT -d "{\"transition\": {\"id\": \"721\"}}" -H "Content-Type: application/json" http://localhost:8080/jira/rest/api/2/issue/KEY-12345/transitions

#If you want to both make a comment and perform a transition do:
"{\"update\": {\"comment\": [{\"add\": {\"body\": \"Transitioned as all sub-tasks closed\"}}]},\"transition\": {\"id\": \"721\"}}"

#Get a list of all users
#This returns a list of all users with the letter 'a' in them
#Playing around it looks like the query doesn't permit regular expressions
