Those 2 commands are running in separate shells. To get the code, you should be able to check err.code in your callback. If that doesn’t work, you need to add an exit event handler e.g. dir = exec(“ls -la”, function(err, stdout, stderr) { if (err) { // should have err.code here? } console.log(stdout); }); dir.on(‘exit’, … Read more
From MSDN Documentation: Remarks This function returns immediately. If the specified thread has not terminated and the function succeeds, the status returned is STILL_ACTIVE. If the thread has terminated and the function succeeds, the status returned is one of the following values: The exit value specified in the ExitThread or TerminateThread function. The return value … Read more
This likely doesn’t work with start, as that starts a new window, but to answer your question: If the command returns a error level you can check the following ways By Specific Error Level commandhere if %errorlevel%==131 echo do something By If Any Error commandhere || echo what to do if error level ISN’T 0 … Read more
I had the exact same error, and tried everything under the sun, including what was suggested elsewhere on this page. What the problem was for me was that in Keychain Access, the actual Apple WWDR certificate was marked as “Always Trust”. It needed to be “System Defaults”. That goes for your Development and Distribution certificates, … Read more
The accepted answer is basically correct, I just want to clarify things. The following example works well: #!/bin/bash cleanup() { rv=$? rm -rf “$tmpdir” exit $rv } tmpdir=”$(mktemp)” trap “cleanup” EXIT # Do things… But you have to be more careful if doing cleanup inline, without a function. For example this won’t work: trap “rv=$?; … Read more
I suggest you instantiate a Queue.Queue before starting the thread, and pass it as one of the thread’s args: before the thread finishes, it .puts the result on the queue it received as an argument. The parent can .get or .get_nowait it at will. Queues are generally the best way to arrange thread synchronization and … Read more
Upon executing a command as $(command) allows the output of the command to replace itself. When you say: a=$(false) # false fails; the output of false is stored in the variable a the output produced by the command false is stored in the variable a. Moreover, the exit code is the same as produced by … Read more
This is a known issue with PowerShell. Executing a script with -file returns an exit code of 0 when it shouldn’t. (Update: The links below no longer work. Please look for, or report, this problem on PowerShell: Hot (1454 ideas) – Windows Server) https://connect.microsoft.com/PowerShell/feedback/details/777375/powershell-exe-does-not-set-an-exit-code-when-file-is-used https://connect.microsoft.com/PowerShell/feedback/details/750653/powershell-exe-doesn-t-return-correct-exit-codes-when-using-the-file-option Since using -command wasn’t working for you, you could try … Read more
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 … Read more
There actually doesn’t seem to be a lot of explanation on this subject apparently but the exit codes are supposed to be used to give an indication on how the thread exited, 0 tends to mean that it exited safely whilst anything else tends to mean it didn’t exit as expected. But then this exit … Read more
