Shell script to track Jira ticket status

Description

• The curlFunction function sends a get request to get issue data in Jira and this data is stored in result.txt
• The functions parsingFunctionFirstMethod and parsingFunctionSecondMethod are parsing data functions (in different ways)
• The sendMailToSlack function sends a message about status change to the slack channel
• The sendMailToEmail function sends an issue status change message to an email
• The startApplication function starts the application if the issue status changes
• An infinite loop is started that checks the status and takes action

Examples for running the script:

Slack

bash Script <baseJiraURL> <jiraUser> <jiraPassword> <issueID> <DirectoryForFile> slack <HookSlack>

<T01DWK7PKCY/B01D70VUBMH/BfjzoOeNm64NrtR6mLuVfLfe> part of hooks url passed as parameter

Email

bash Script <baseJiraURL> <jiraUser> <jiraPassword> <issueID> <DirectoryForFile> email <EmailRecipient>

Application

bash Script <baseJiraURL> <jiraUser> <jiraPassword> <issueID> <directoryForFile> app <NameScriptOrApplication>

baseJiraURL                       host name of the Jira server. For example: jira.test.by
JiraUser/JiraPassword		  auth information to connect to Jira
issueID                           key and number of the issue. For example: TEST-19
path                              path name where result.txt data stored
optionSendMail                    options: slack, email or app

Script:

If needed, specify **EMAIL ADDRESS** and **PASSWORD** in the script

baseJiraURL=$1
jiraUser=$2
jiraPassword=$3
issueID=$4
path=$5
optionSendMail=$6
to=$7

from=**EMAIL ADDRESS**
emailPasswordForSendMail=**PASSWORD**
