Im using the OS Process Sampler to execute the following shell command

```
cat ${myDataFile} | myProcessor.sh --param1 valueParam1 --param2 valueParam2

command: cat 
Standard Input(stdin): ${myDataFile}
working directory: ${myHome}
command Parameters: | myProcessor.sh --param1 valueParam1 --param2 valueParam2

```

Response

```
cat: | myProcessor.sh --param1 valueParam1 --param2 valueParam2: No such file or directory

```

Clearly "cat" is tying to ca the command parameter as a file. 

How to overcome this issue. This is running on a AWS EC2 environment
