Over the past few days, some readers have told us they have seen an example of Linux Runtime.getruntime .exec.

 

 

Suggested solutions might include using commons.io, handling the error stream, and therefore using exceptions. I would suggest summarizing about 8 or later static data for use in Java like this:

  public List  execute (last line command) throws ExecutionFailedException, InterruptedException, IOException    Try        Return (command, 0, zero, false);     view (ExecutionTimeoutException e) returns null; / * Business is impossible! * /public static list  execute (last command word String, last long timeout, last TimeUnit timeUnit) throws ExecutionFailedException, ExecutionTimeoutException, InterruptedException, IOException    Execute return (command, 0, zero, true);List of public sounds  execute (last string command, last significant timeout, last TimeUnit, logical destruction OnTimeout) throws ExecutionFailedException, ExecutionTimeoutException, InterruptedException, IOException    Process process = new ProcessBuilder () .Order ("bash", "-c", command) .start ();    ! = if (timeUnit null)        if (process.waitFor (timeout, timeUnit))            if (process.exitValue () == 0)                Returns IOUtils.readLines (process.getInputStream (), StandardCharsets.UTF_8);                              throw a new ExecutionFailedException ("Execution" did not work: + Command, process.exitValue (), IOUtils.readLines (process.getInputStream (), StandardCharsets.UTF_8));                     another            if (destroyOnTimeout) process.destroy ();            throw new ExecutionTimeoutException ("Separate execution by time:"+ command);             another        if (process.waitFor () == 0)            IOUtils return.readLines (process.getInputStream (), StandardCharsets.UTF_8);         another            add a new exception ExecutionFailedException ("Failed to execute:" + have, process.exitValue (), IOUtils.readLines (process.getInputStream (), StandardCharsets.UTF_8));            the public static class ExecutionFailedException throws an exception    very long private static final serialVersionUID = 1951044996696304510L;    internal final int exitCode;    custom final list  errorOutput;    public generic ExecutionFailedException (last String message, final int exitCode, completion of error list )        super (message);        this.exitCode implies ExitCode;        this.errorOutput = errorOutput;        public int getExitCode () creates this.exitCode;        public list  getErrorOutput ()        produce this.errorOutput;    Old Fashioned Public Class ExecutionTimeoutException Extends Exception    static final long sensitive serialVersionUID matches 4428595769718054862L;    public ExecutionTimeoutException (last string message)        super (message);
