                                     StreamConsumer systemOut,
                                     StreamConsumer systemErr,
                                     int timeoutInSeconds)
                              throws CommandLineException

Throws:

CommandLineException

executeCommandLine

public static int executeCommandLine(Commandline cl,
                                     InputStream systemIn,
                                     StreamConsumer systemOut,
                                     StreamConsumer systemErr)
                              throws CommandLineException

Throws:

CommandLineException

executeCommandLine

public static int executeCommandLine(Commandline cl,
                                     InputStream systemIn,
                                     StreamConsumer systemOut,
                                     StreamConsumer systemErr,

                              throws CommandLineException

Parameters:

cl -

systemIn -

systemOut -

systemErr -

timeoutInSeconds -

Returns:

Throws:

CommandLineException - or CommandLineTimeOutException if time out occurs

getSystemEnvVars

public static Properties getSystemEnvVars()
                                   throws IOException

Gets the shell environment variables for this process. Note that the returned mapping from variable names to values will always be case-sensitive regardless of the platform, i.e. getSystemEnvVars().get("path") and getSystemEnvVars().get("PATH") will in general return different values. However, on platforms with case-insensitive environment variables like Windows, all variable names will be normalized to upper case.

Returns:

The shell environment variables, can be empty but never null.

Throws:

IOException - If the environment variables could not be queried from the shell.

getSystemEnvVars

public static Properties getSystemEnvVars(boolean caseSensitive)
                                   throws IOException

Return the shell environment variables. If caseSensitive == true, then envar keys will all be upper-case.

Parameters:

caseSensitive - Whether environment variable keys should be treated case-sensitively.

Returns:

Properties object of (possibly modified) envar keys mapped to their values.

Throws:

IOException

killProcess

public static void killProcess(long pid)

Kill a process launched by executeCommandLine methods. Doesn't work correctly on windows, only the cmd process will be destroy but not the sub process (Bug ID 4770092)

Parameters:

pid - The pid of command return by Commandline.getPid()

isAlive

public static boolean isAlive(long pid)

isAlive

public static boolean isAlive(Process p)

translateCommandline

public static String[] translateCommandline(String toProcess)
                                     throws Exception

Throws:

Exception

quote

public static String quote(String argument)
                    throws CommandLineException

Deprecated. Use StringUtils.quoteAndEscape(String, char, char[], char[], char, boolean), StringUtils.quoteAndEscape(String, char, char[], char, boolean), or StringUtils.quoteAndEscape(String, char) instead.

Put quotes around the given String if necessary.

If the argument doesn't include spaces or quotes, return it as is. If it contains double quotes, use single quotes - else surround the argument by double quotes.

Throws:

CommandLineException - if the argument contains both, single and double quotes.

public static String quote(String argument,
                           boolean wrapExistingQuotes)
                    throws CommandLineException

Deprecated. Use StringUtils.quoteAndEscape(String, char, char[], char[], char, boolean), StringUtils.quoteAndEscape(String, char, char[], char, boolean), or StringUtils.quoteAndEscape(String, char) instead.

Put quotes around the given String if necessary.

If the argument doesn't include spaces or quotes, return it as is. If it contains double quotes, use single quotes - else surround the argument by double quotes.

Throws:

CommandLineException - if the argument contains both, single and double quotes.

                           boolean wrapExistingQuotes)
                    throws CommandLineException

Deprecated. Use StringUtils.quoteAndEscape(String, char, char[], char[], char, boolean), StringUtils.quoteAndEscape(String, char, char[], char, boolean), or StringUtils.quoteAndEscape(String, char) instead.

Throws:
