Top Forums Shell Programming and Scripting How to run same script on multiples servers Post 302336315 by mglenney on Tuesday 21st of July 2009 08:15:48 PM

If you run an ssh command remotely the stdout from the command is returned to your local terminal. You can capture it there and send to a local file. So, say you want the output of the date command from multiple servers put in a file and then emailed. You could just:

Code:
#!/bin/bash
hosts=( host1 host2 host3 )
for ((i=0;i<${#hosts[@]};i++)); do
  ssh me@${hosts[$i]} "date" >> outputfile &
done
wait
mail -s "Results" me@domain.com < outputfile

if it's a script that has to run they you could have it in a shared location and run it

Code:
  ssh me@${hosts[$i]} "/path/to/script.sh" >> outputfile &

If there's something in the script that varies by server you're just going to have to work that out. Either have a different script in each location or, if you need more automation, have it accept command line input for the difference and pass it with the script:

Code:
#!/bin/bash
hosts=( host1 host2 host3 )
var=( var1 var2 var3 )
for ((i=0;i<${#hosts[@]};i++)); do
  ssh me@${hosts[$i]} "/path/to/script.sh ${var[$i]}" >> outputfile &
done
wait
mail -s "Results" me@domain.com < outputfile

(As you can see I'm an array junkie. Might be overkill here. Dunno. Works for me though Smilie If you need any parts of my example explained please don't hesitate to ask)
