exit-code

I am planning to use the return code of the C# executable in one of my shell script. I have two options: Returning a int value from the main method class MainReturnValTest { static int Main() { //... return 0; } } (OR) Using Environment.Exit with an exit code class MainReturnValTest { static void Main() { //... Enviroment.Exit(exitCode); } } Is it fine to use any of the above ways to return value from the executable? Or is one of them preferred over other? Environment.Exit() is a rude abort. It instantly terminates the process. Use it only when you detect a gross failure, it is appropriate in

Is there a list of exit codes and meanings for java process terminations? Because I have an exit code 23 and i don't know what it can be (I cannot change the log to see the full stack trace because it sits in a different remote server). I browsed it for hours and couldn't find any mentioning of exit code 23. In your Java application, when you call System.exit(n); , then the Java runtime environment will return n as the exit code back to the operating system. What the number means depends on the program you are running - not Java itself, but the program you are running produces this number.

The application I am building is still running in memory (checked in Task Manager) after it is closed using Application.Exit() . Because of this when I am running it again after closing it as mentioned above, I am getting this error "Only one instance at a time". Can you please tell me how to completely close my application? It seems that this is a Windows ap and you are calling System.Windows.Forms.Application.Exit() but there is a thread still running in the background. Have you tried Application.ExitThread(); Environment.Exit(); You could kill the process as Jonesy mentioned, passing in the

I want to know whether any commands in a bash script exited with a non-zero status. I want something similar to set -e functionality, except that I don't want it to exit when a command exits with a non-zero status. I want it to run the whole script, and then I want to know that either: a) all commands exited with exit status 0 -or- b) one or more commands exited with a non-zero status e.g., given the following: #!/bin/bash command1 # exits with status 1 command2 # exits with status 0 command3 # exits with status 0 I want all three commands to run. After running the script, I want an indication

I am trying to return a bigger value like 1000 from my main function, but when I type echo $? it displays 0. If I return a smaller value like 100 it displays the correct value. My Code: int main(void) { return 1000; } Is there any limitation on the values which we can return? There are two related concepts here: C exit status, and bash return code. They both cover the range 0-255, but bash uses numbers above 126 for it's own purposes, so it would be confusing to return those from your program. To be safe limit exit status codes to 0-127, as that is most portable, at least that is implied by

On the diff man-page I've found these exit values: 0 No differences were found. 1 Differences were found. >1 An error occurred. Are there different exit values above 1 for different errors? It depends on your diff command. Mine (GNU diffutils 3.0) says: An exit status of 0 means no differences were found, 1 means some differences were found, and 2 means trouble. Normally, differing binary files count as trouble, but this can be altered by using the -a or --text option, or the -q or --brief option. David W. There maybe, or there may not be different error codes depending upon the version of
