   echo "on ship: desktop captured in ~/tmp/screenshotX.png"
+Make it executable and test:
+**remote_screenshot.bash**
+And view the figure it made: **~/tmp/screenshotX.png**
+====Step 2: On Shore====
+And on the landside server, make this script to execute screenshotX.png on the ship, and rsync the file back. Call this one **remote_shipX_screenshot.bash**
+## begin script to get the screenshot back to the landserver ##
+  #!/bin/bash
+  ## works best if there is an ssh key on the remote machine
+  # - make the remote command for screenshot
+  # - this example requires a port to log in
+  ssh  -p ##### shipuser@shipserver /path/to/remote_screenshotX.bash
+  ## bring it back, put it in /tmp
+  echo "bringing back the screenshot"
+  rsync -Pv -e 'ssh -p 56565' shipuser@shipserver:tmp/screenshotX.png /tmp
+  ## move it to the location of choice
+  mv /tmp/screenshotX.png /path/to/server/shipX/shipuser_screenshotX.png
+Test it by running
+**/path/to/scripts/remote_shipX_screenshot.bash**
+and view the png
+====Step 3: Wrapping with an HTML====
+Now if you are on the landserver you can look at the png file. If you want the png served up on a web location, you can look at it directly. If you want an html to wrap it, so it refreshes every so often,
+put this in the same location as shipuser_screenshotX.png:
+**shipuser_screenshotX.html**
+##begin html file to display shipuser_screenshtX.png ##
+  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
+  <html><head>
+  <meta http-equiv="Refresh" content="300">
+  <title>ShipX Desktop</title></head>
+  <body>
+  <img src="./shipuser_screenshotX.png" style="width: 100%"/>
+  <br>
+  <br>
+  <br>
+  </body></html>
+Then you can browse to this page and it will refresh every 5 min: http://shipserver/path/to/shipX/shipuser_screenshotX.html
+====Step 4: Creating a cronjob====
+Make the <color #1c1ced>landuser@landserver</color> have a crontab entry to run the program
+hourly at 10 min past the hour.
+**NOTE:** crontab does not have a good environment so if you need to set your PATH, do so in a bash_env file and source that before running the command. That's how I did it.  Or be very explicit about setting your PATH first.This is all **one line**:
+*/1 * * * (date +\%F\ \%T; cd /path/to/myenv; . ./bash_env;
+  /path_to_script/remote_shipX_screenshot.bash) >> /path/to/logfiles/shipXscreenshot.log 2>&1
+**Another note:** I also outputted the stdout to a log file.
+====Step 5: Running from your laptop====
+  ssh landuser@landserver /path/to/scripts/remote_shipX_screenshot.bash
+or make an alias:
+  alias get_shipX_screenshot='ssh landuser@landserver /path/to/scripts/remote_shipX_screenshot.bash; echo o
+  "view this file"; echo "";echo http://shipserver/path/to/shipX/shipuser_screenshotX.html'
