问题 Is there anyway (commandline tools) to calculate MD5 hash for .NEF (also .CR2, .TIFF) regardless any metadata, e.g. EXIF, IPTC, XMP and so on? The MD5 hash should be same once we update any metadata inside the image file. I searched for a while, the closest solution is: exiftool test.nef -all= -o - -m | md5 but 'exiftool -all=' still keeps a set of EXIF tags in the output file. The MD5 hash can be changed if I update remaining tags. 回答1: ImageMagick has a method for doing exactly this. It is

问题 I want to create a camera calibration application with opencv for a university course. I have created a command line tool application on macOS High Sierra. Unfortunately it came without an info.plist file. My application crashes with the following error message: CameraCalibration[2314:193066] [access] This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCameraUsageDescription key with a string value

问题 I am writing a command-line tool for Android (such that it would be called via 'adb shell' or the like, as opposed to being launched via the Android interface). I want to write something that uses the same kind of information as the 'pm list packages' tool that you can run from an adb shell, which I presume uses getPackageManager() or something like it. So I've figured out how to compile and run a Java tool in Dalvik, but I can't figure out how to get it the context it needs for

问题 How would a keep a command-line tool running for ever. This is my code: #import <Foundation/Foundation.h> int main (int argc, const char * argv[]) { @autoreleasepool { [[NSDistributedNotificationCenter defaultCenter] addObserverForName:nil object:nil queue:nil usingBlock:^(NSNotification *notification) { NSLog(@"%@", notification); }]; //Keep alive... } return 0; } 回答1: You need to enter into a runloop using either CFRunLoop or NSRunLoop. Try: [[NSRunLoop currentRunLoop] run]; 回答2: In Swift 4

问题 I'm try to determine how to use the zip cmd line tool to move a file (uncompressed) in to a zip of compressed files (ie I want a zip in the end with all files but one compressed, b/c the one file is another compressed file). Anyone know how to do this? 回答1: It looks like you could use -n option to just store the files with defined extensions together with -g option to append the file to archive. I didn't test it, but something like this should do the trick: zip -gn .foo archive.zip

问题 I've created a console application using the Xcode OS X Command Line Tool project template. When everything is said and done, where are the actual "Release" binaries placed on my machine? After searching SO, I found out where I could find the "Debug" binaries: ~/Library/Developer/Xcode/DerivedData/Project/Build/Products/Debug Where can I find the "Release" binaries? Or is there additional setup that is needed in Xcode to output these binaries so that I can distribute console application? 回答1:

问题 Having trouble getting unit tests set up for a specific scenario. Here's what I'm trying: In Xcode 4.5, I created a simple OSX "Command Line Tool" application project (Foundation). Note that Xcode does not provide the option to add unit tests to a "Command Line Tool" project automatically – so please don't suggest ticking the ticky-box; it ain't there :-/ In my project, I created a trivial example class that I'd like to test; e.g. "Shape". I followed instructions in Apple's Xcode Unit Testing
