exit-code

问题 Is it possible to write a method that System.exit will call when you terminate a program? 回答1: Use Runtime.getRuntime().addShutdownHook(Thread). 回答2: Shutdown hooks are the answer... here is an article on them. They do not come without issues (some of them are discussed in the article). 回答3: You can use a shutdown hook. http://download.oracle.com/javase/6/docs/api/java/lang/Runtime.html#addShutdownHook(java.lang.Thread) Note that shutdown hooks will not run if the VM aborts abnormally or

问题 I have a bash shell script that calls a few PHP scripts like this. #!/bin/bash php -f somescript.php php -f anotherscript.php I want to compose an error log and/or an activity report based on the results of those scripts. Is there any way I can get the exit status of the php script in the shell script? I could either use integer exit statuses or string messages. 回答1: You can easily catch the output using the backtick operator, and get the exit code of the last command by using $? : #!/bin

问题 Background: I am attempting to get email notification upon failure of a scheduled task. My task can indicate failure via exit code (errorlevel) and I want to use that and follow the filter approach described in this answer to trigger an email. Problem: I am getting inconsistent behavior from Task Scheduler on different machines and versions of Windows. To test, I'm using the following very simple task. Run only when user is logged on. (where "user" is the current user) Action: Start a program

问题 I am having an issue running Testcafe through cucumber. for whatever reason, When I run testCafe through cucumber, the process will always exit with exit code 0 even in the test fails. If I run puppeteer through cucumber I don't get this issue. I am thinking that this behavior is due to the way I have things set up in my hooks file where I am not properly interpreting the test cafe exit code. In my hooks file, I am creating a testCafe runner and in my Before hook and then closing it during my

问题 Basically, let's say that I have a batch file that calls myapp1.exe and myapp1.exe exits with Exit Code 1. Can the batch file capture this information and either force the batch file to exit with that same exit code or perform some other logic? 回答1: @echo off rem ... set errorlevel= MyApp1.exe exit /b %errorlevel% would be the explicit variant. 回答2: You could try using errorlevels. Some more info here. 回答3: The accepted answer is correct, but if you are using call to call another batch script

问题 when program exits, the information is given: *** glibc detected *** double free or corruption (!prev): 0x09a8fcb8 *** It seems like double free at one object. Then I used gdb to debug the coredump file. The following is the bt result(more traces are not posted): #0 0x005197a2 in _dl_sysinfo_int80 () from /lib/ld-linux.so.2 #1 0x0055a825 in raise () from /lib/tls/libc.so.6 #2 0x0055c289 in abort () from /lib/tls/libc.so.6 #3 0x0058ecda in __libc_message () from /lib/tls/libc.so.6 #4

问题 When running "git status" or even "ls" from an apache process, I will frequently get no standard output or error, and an exit status code of -6. Other times, it just works. Any ideas why this is occurring or what it means? 回答1: If you are on a network with a lot of people, you may be running out of available concurrent connections. This assumes you are on Linux when you talk about your remote. The default of 10 concurrent secure collections is not enough if you have lots of simultaneous

问题 In my .nsi file I am calling ExecWait '"$INSTDIR\application.exe" ' $0 . In application.exe I am returning exit codes for success and failures. How to catch those exit codes in .nsi file. 回答1: If there is an error performing ExecWait, then the contents of the user variable passed in is undefined. To simply check if the program executed correctly or not, check the error flag. (btw, NSIS expects zero for success and non-zero for error) ClearErrors ExecWait '"$INSTDIR\application.exe"' IfErrors
