Class ShellCommand

Method Details

• execute

  @Deprecated public void execute​(String shellCommand)

  Deprecated.

  unused

  Passes a command to the shell for execution and returns immediately without waiting for an exit status. All output produced by the executed command will go to STDOUT and STDERR as appropriate, and can be read via getOutputStream() and getErrorStream(), respectively. Input can be passed to the STDIN of the shell process via getInputStream(). Warning, no good way to quote or escape spaces in arguments with this method.

  Parameters:

  shellCommand - The command for the shell to execute.

• executeAndWait

  @Deprecated public boolean executeAndWait​(String shellCommand)

  Deprecated.

  unused

  Passes a command to the shell for execution. This method blocks until all of the command's resulting shell processes have completed. All output produced by the executed command will go to STDOUT and STDERR as appropriate, and can be read via getOutputStream() and getErrorStream(), respectively. Input can be passed to the STDIN of the shell process via getInputStream(). Warning, no good way to quote or escape spaces in arguments with this method.

  Parameters:

  shellCommand - The command for the shell to execute.

  Returns:

  true if the spawned shell process returns an exit status of 0 (indicating success), else false.

• executeAndWaitTimed

  @Deprecated public boolean executeAndWaitTimed​(String shellCommand, int seconds)

All output produced by the executed command will go to STDOUT and STDERR as appropriate, and can be read via getOutputStream() and getErrorStream(), respectively. Input can be passed to the STDIN of the shell process via getInputStream(). Warning, no good way to quote or escape spaces in arguments with this method.

  Parameters:

  shellCommand - The command for the shell to execute.

  seconds - The method will return true if this number of seconds elapses without the process returning an exit status. A value of 0 here disables waiting.
