Description

Based on info from http://peterdowns.com/posts/open-iterm-finder-service.html but with modified behavior and fixed to work with iTerm2 version 3 or later. It will not work with older versions of iTerm. The modified behavior is to open a new terminal window for each invocation instead of reusing an already open window. Update - The original author released a build script for the newer iTerm2 versions at https://github.com/peterldowns/iterm2-finder-tools that keeps the original behavior of reusing an open iTerm2 window.

To open iTerm2 at selected folder with keyboard shortcut

1. Run Automator, select a new Service
2. Select Utilities -> Double click ‘Run AppleScript’
3. Service receives selected 'folders' in 'finder.app'
4. Paste script:

rimusz

#!/bin/sh
#This is a simple bash script that will poll github for changes to your repo,
#if found pull them down, and then rebuild and restart a Jekyll site running 
#in Nginx. Note, we cannot use cron to schedule a job every 5 seconds, so we create
#a script that executes an infinite loop that sleeps every 5 seconds
#We run the script with nohup so it executes as a background process: $nohup ./update-jekyll

while true
do

Scenario

Your work involves using a corporate network for Internet access, which blocks accessing anything other than port 22/80/443 on a remote server.

Example

Kubernetes services deployed with NodePorts use a high TCP port range ~ 30000 which is blocked
