* Batch mode (via `-b`) and execution times (via `-n`) must be explicitly specified for `dashboard`, otherwise batch script cannot terminate.
* Batch mode execution times (via `-n`) must be explicitly specified for `dashboard`, otherwise batch script cannot terminate.
* Commands such as `watch`/`tt`/`trace`/`monitor`/`stack` should include `-n` option to ensure the script can be able to quit.
* Also consider to use `async` (for example: `watch c.t.X test returnObj > &`) to put commands run at background and get the output from the log file, see more from [asynchronous job](async.md)
#### Step 2: Run the script
Use `-b` to turn on batch mode, and use `-f` to specify the script file. By default the result will be output to the standard output, but you can redirect the output to the file like this:
Use `-f` to specify the script file. By default the result will be output to the standard output, but you can redirect the output to the file like this:
```bash
./as.sh -b -f /var/tmp/test.as 56328 > test.out
./as.sh -f /var/tmp/test.as 56328 > test.out
```
Use `-c` also can specify the commands, like this:
<p>Create a <codeclass="docutils literal notranslate"><spanclass="pre">test.as</span></code> script suffixed with <codeclass="docutils literal notranslate"><spanclass="pre">as</span></code>. Here <codeclass="docutils literal notranslate"><spanclass="pre">as</span></code> is suggested for the suffix of the filename, but in fact any suffix is acceptable.</p>
