Colas,
Bash’s -c option expects commands in a string which follows. Therefore, this will work: I’m using /usr/bin/touch as an example, rather than your example of pico, which is an interactive text editor.
NSTask * myTask = [[NSTask alloc]init];
NSArray * arguments = @[@"-c", @"/usr/bin/touch /Users/colas/touchedFile.txt", @"-l"];
[myTask setCurrentDirectoryPath:@"/"];
[myTask setLaunchPath:@"/bin/bash"];
[myTask setArguments:arguments];
[myTask launch];
This will touch a file named “touchedFile.txt” at the root of your home directory.
