Examples

​
.NET

<!-- Creating an out item to hold output data -->
<arc:set attr="out.data" value=""/>
<!-- Creating an input item, 'executable' and assigning input parameters -->
<arc:set attr="executable.name" value="C:\\temp\\foo.bat" />
<!-- Creating an array of arguments that will be passed into the command or program -->
<arc:set attr="executable.argarray#1" value="arg1"/>
<arc:set attr="executable.argarray#2" value="arg2"/>
<arc:set attr="executable.argarray#3" value="arg3"/>
<!-- Calling the operation, passing in the input item and setting an output item -->
<arc:call op="sysExecute" in="executable" out="results">
  <!-- Populating the data attribute of the out item -->
  <arc:set attr="out.data" value="[results.sys:output]" />
</arc:call>
<!-- Setting the filename of the out item and pushing it as an output file -->
<arc:set attr="out.filename" value="echo.txt"/>
<arc:push item="out"/>
The batch file called here is programmed to output Hello world along with a list of the arguments that were passed in. The output of this script (echo.txt) looks like this: 
Hello world.
The first argument is arg1
The second argument is arg2
The third argument is arg3

​
Linux

<!-- Creating an out item to hold output data -->
<arc:set attr="out.data" value=""/>
<!-- Creating an input item, 'executable' and assigning input parameters -->
<arc:set attr="executable.name" value="bash" />
<arc:set attr="executable.arguments" value="/mnt/c/scripts/helloworld.sh lion tiger bear" />
<!-- Calling the operation, passing in the input item and setting an output item -->
<arc:call op="sysExecute" in="executable" out="results">
  <!-- Populating the data attribute of the out item -->
  <arc:set attr="out.data" value="[results.sys:output]" />
</arc:call>
<!-- Setting the filename of the out item and pushing it as an output file -->
<arc:set attr="out.filename" value="echo.txt"/>
<arc:push item="out"/>
The batch file called here is programmed to output hello linux world along with a list of the arguments that were passed in. The output of this script (echo.txt) looks like this:
