synchronized String org.sleuthkit.autopsy.coreutils.ExecUtil.execute ( final String  aCommand,
final String...  params 
) throws IOException, InterruptedException

Execute a process. Redirect asynchronously stdout to a string and stderr to nowhere. Use only for small outputs, otherwise use the execute() variant with Writer.

Parameters
aCommandcommand to be executed
paramsparameters of the command
Returns
string buffer with captured stdout

synchronized int org.sleuthkit.autopsy.coreutils.ExecUtil.getExitValue ( )

Gets the exit value returned by the subprocess used to execute a command.

Returns
The exit value or the distinguished value -100 if this method is called before the exit value is set.
