Ultimately I need to be able to call a telnet session from a Perspective button, however I am unable to get ANYTHING to execute.

```
system.util.execute(["/bin/bash","/home/user/trancollector.sh","shell=true"])
#system.util.execute(["x-terminal-emulator"])
#system.util.execute(["/usr/bin/x-terminal-emulator"])
#system.util.execute(["xterm"])

```

Every attempt ends with:  
java.io.IOException: java.io.IOException: Cannot run program “/bin/bash”: CreateProcess error=2, The system cannot find the file specified

What am I missing?? Only see the error on Designer, Client just acts as thought there is no script on the button. (Yes same PC).  
Thanks

This isn't going to work through a web browser. You're using a browser or perspective workstation because it might work with that?

`system.util.execute` does work on the gateway scope, where Perspective scripts run, but keep in mind that’s _the gateway scope_ - so your execute call is happening on the gateway, not locally to your clients. Also, your Ignition service is likely running with a different PATH than you have in a standard logon session.
