nstask

I have a PHP script which has mutliple sleep() commands. I would like to execute it in my application with NSTask . My script looks like this: echo "first\n"; sleep(1); echo "second\n"; sleep(1); echo "third\n"; I can execute my task asynchronously using notifications: - (void)awakeFromNib { NSTask *task = [[NSTask alloc] init]; [task setLaunchPath: @"/usr/bin/php"]; NSArray *arguments; arguments = [NSArray arrayWithObjects: @"-r", @"echo \"first\n\"; sleep(1); echo \"second\n\"; sleep(1); echo \"third\n\";", nil]; [task setArguments: arguments]; NSPipe *p = [NSPipe pipe]; [task

I am making a small app that deletes log files. I am using an NSTask instance which runs rm and srm (secure rm) to delete files. I want to be able to delete files in: /Library/Logs ~/Library/Logs The issue is that the user account does not have permissions to access some files in the system library folder, such as the Adobe logs subfolder and others. For example, only the "system" user (group?) has r/w permissions for the Adobe logs folder and its contents, and the current user doesn't even have an entry in the permissions shown in the Get Info window for the folder. What I want to be able to

I am trying to read the contents of a URL synchronously for a simple command-line batch script in Swift. I am using cURL for simplicity's sake - I know I could use NSURLSession if I had to. I am also building this with swift build using the open-source version of Swift on OSX. The problem is that on certain URLs, the NSTask never terminates, if stdout has been redirected to a pipe. // This will hang, and when terminated with Ctrl-C reports "(23) Failed writing body" import Foundation let task = NSTask() let pipe = NSPipe() task.launchPath = "/usr/bin/curl" task.arguments = ["http://trove.nla

This question already has an answer here: How to use NSTask as root? 5 answers I need to basically do a "sudo" but, I need to give that kind of permission to my NSTask code. Is this possible? Thanks, Elijah tally Look here: http://www.sveinbjorn.org/STPrivilegedTask http://www.sheepsystems.com/sourceCode/authTasksCocoa.html HTH :-) Carlos P If you're looking for a more lightweight solution, I wrote this generic implementation which should achieve what you want: - (BOOL) runProcessAsAdministrator:(NSString*)scriptPath withArguments:(NSArray *)arguments output:(NSString **)output

Here is my code: task = [[NSTask alloc] init]; [task setCurrentDirectoryPath:@"/applications/jarvis/brain/"]; [task setLaunchPath:@"/applications/jarvis/brain/server.sh"]; NSPipe * out = [NSPipe pipe]; [task setStandardOutput:out]; [task launch]; [task waitUntilExit]; [task release]; NSFileHandle * read = [out fileHandleForReading]; NSData * dataRead = [read readDataToEndOfFile]; NSString * stringRead = [[[NSString alloc] initWithData:dataRead encoding:NSUTF8StringEncoding] autorelease]; So I'm trying to replicate this: cd /applications/jarvis/brain/ ./server.sh but using NSTask in objective-c

I've an open source project (gdal) that I want to compile and run as part of an iOS app. I had been expecting to use NSTask but I see now that it was removed in iOS 3.0. I've also seen elsewhere that running external applications, though this would be a resource in my app's bundle, is not allowed. Has anyone else found a way to run commandline tools within their iOS applications? It wasn't removed in 3.0, it was never there. There is no way to run separate processes on the iPhone. GDAL appears to be under an MIT style license and has a library interface, so directly linking it into an iPhone
