This is getting off topic but I'd like to run some sqlite commands. After executing folder change commands in the .sh file, these commands execute: sqlite3 myDB.sqlite .import dbArea.txt Area When I run the .sh file from Terminal, I'm at an sqlite prompt. The import command doesn't execute. Any ideas what's going on? Thanks. This is getting off topic but I’d like to run some sqlite commands.

Once you have added the script, MyScript.sh, to your Xcode project, you can have the shell run it like: NSString *pathToMyScript = [[NSBundle mainBundle] pathForResource:@"MyScript" ofType:@"sh"]; [[NSTask launchedTaskWithLaunchPath:@"/bin/sh" arguments:[NSArray arrayWithObject:pathToMyScript]] waitUntilExit]; What I would suggest doing is putting those dependent shell commands together in their own shell script, and then executing the shell script.

This is great! Is there a way to execute several commands within the same Terminal session? I'm calling executeShellCommandSynchronously multiple times to traverse folders and and retreive contents of a file: cd / cd Users/theuser/Thefolder vi somefile.txt The problem is that each command executes in its own Terminal session. So the second command gives a folder not found because I'm still in the build/debug folder. Any suggestions? Thanks. Thanks. This is great!
