com.ergotech.vib.manipulators.CommandExecutor

This manipulator is used to run a native command on the computer where MIX or the deployed TransSECS software is running. For example, to get a list of image png files in a directory, on Linux run “ls *.png -a -1” and on Windows the equivalent run in cmd /c “dir *.png /b”.

This Bean has two inputs which are used as triggers to run the command in the “command” property. The output of the Command Executor is the result of the command execution, but can be empty if no output is generated. Parameters can be passed to the command as an Array Value Object to the “Argument Input” trigger, where each element of the ArrayValueObject is a {[stringvaluebojects|StringValueObject]] with a parameter.

The Output of this Bean is the text which would be generated if the command were executed in a command shell or terminal.

To get a list of png image files in directory C:\pathtoimages\myimages on Windows, enter this as the “Command”

cmd /c dir C:\pathtoimages\myimages\*.png /b

and connect a Button to the “Trigger” input to test. The output can be displayed in a TextArea on the Design screen and should contain a list of png files in that directory.

In Linux, the Command will be similar, but in this example we change to the images directory then get the list of png files in it:

 (cd /home/myname/mypath/images && ls -a -1 *.png)

Command: The command to be executed when triggered (either the “Trigger” or the “Argument Input” can be used as a trigger).
