exit-code

问题 I recently learned that the proper way to shut down a Spring Boot application is this: public class Application { @Bean public ExitCodeGenerator exitCodeGenerator() { return new ExitCodeGenerator() { @Override public int getExitCode() { return 0; } }; } public static void main(String[] args) throws Exception { System.exit(SpringApplication.exit(SpringApplication.run(Application.class, args))); } } This should return an exit code of 0, or whatever I configure it to return in the getExitCode()

问题 As it can be seen from this question we start a new instance of Inno Setup: Instance := ShellExecute(0, '', ExpandConstant('{srcexe}'), Params, '', SW_SHOW); where function ShellExecute(hwnd: HWND; lpOperation: string; lpFile: string; lpParameters: string; lpDirectory: string; nShowCmd: Integer): THandle; external 'ShellExecuteW@shell32.dll stdcall'; All the code from this question's answer I moved to the VCL_Styles.iss file and included it into my main script. The problem is that after I've

问题 What is the correct way to output an exit status in bash? As far as I know, the exit status called by $? corresponds to the status of the last command executed. The script being worked on has a few conditional checks on the files fed as arguments, for example, a check on whether any files were named at all or if a file exists or not. So I have conditional statements like this: if [ $# -eq 0 ] ; then echo "No file name(s) given! \nExit status=$?" exit if [ ! -e "$fName" ] ; then echo "$fName

问题 In Bash, I would like an if statement which is based of the exit code of running a command. For example: #!/bin/bash if [ ./success.sh ]; then echo "First: success!" else echo "First: failure!" fi if [ ./failure.sh ]; then echo "Second: success!" else echo "Second: failure!" fi success.sh #!/bin/bash exit 0 failure.sh #!/bin/bash exit 1 This should print out: First: success! Second: failure! How would I achieve this? Thanks! 回答1: Just remove the brackets: #!/bin/bash if ./success.sh; then

问题 Use process = Runtime.getRuntime.exec("other.sh") to lauch other.sh who exits with 1, however, process.waitFor() returns with 0. Under Linux RedHat 7. other.sh just starts another Java process that returns by System.exit(1) . I've seen the same problem in https://coderanch.com/t/326568/java/exitValue-returns-inconsistent-values. However, it said that this was a JDK bug in 1.4 and was fixed already. However, I am using JDK 1.8. I just want to know if there are any other possibilities leading

问题 I have a code in C that forks itself sometimes, each fork does something then returns an error code. Currently, each child process returns its ID (0..n). void other(int numero){ ... exit(numero); } int main(...){ for(int i = 0; i < 6; i++){ if(fork() == 0){ other(i); } } int order[6]; for(int i = 0; i < 6; i++){ int code; waitpid(0, &code, 0); order[i] = code; // <-- HERE } } Weirdly, this returns a multiple of the real value. By replacing the line I marked with : order[i] = code >> 8; I

问题 Process p = Runtime.getRuntime().exec("screencap -p /storage/sdcard0/test3332.png"); p.waitFor(); String error = "error: " + p.exitValue(); p.exitValue() is equal to 11 How to get the "meaning" or message from this exit code? If this should be available in the command's manual, then where to find this manual? Can someone post a link or a reference ? 回答1: The error message can be retrieved in this way: int ch; StringBuilder sb = new StringBuilder(); while((ch = p.getErrorStream().read()) != -1
