I've got a problem and found no repose in the archives.
I've got a ftp command file called toto.txt
When in the terminal I do :
ftp ftp://me:email@hidden < /pathToDirectory/toto.txt
it work perfectly
But when I use it through cocoa it doesn't work:
task = [[NSTask alloc] init];
[task setLaunchPath: @"/usr/bin/ftp"];
[task setArguments: [NSArray arrayWithObjects:
@"ftp://me:email@hidden";, @"<", @"toto.txt", nil]];
[task launch];
The run log shows the output for connection, but after that enters the
ftp command editor and wait for an entry

I think the problem lies in a standard output or something like that,
but I cant figure it out.
Thanks for help
The < redirection is performed by the shell, not the ftp process. Thus
when you launch ftp directly with NSTask, it treats it as if it had two
arguments, rather than routing stdin to the text file. You have several
options to do what you want:
1) Launch a shell instead of ftp, as in:
[task setLaunchPath:@"/bin/sh"];
[task setArguments:[NSArray arrayWithObjects:@"-c", [NSString /*YOU
MUST WRITE THIS METHOD */stringByAddingShellEscapes:@"/usr/bin/ftp
ftp://me:email@hidden < toto.txt"], nil]];
2) Perform the redirection yourself, the way the shell does:
[task setLaunchPath:@"/usr/bin/ftp"];
[task setStandardInput:[NSFileHandle
fileHandleForReadingAtPath:@"/full/path/to/toto.txt"]];
[task setArguments:[NSArray
arrayWithObject:@"ftp://me:email@hidden";]];
I strongly recommend AGAINST using 1, as it presents issues with shell
escapes in the path to the file that the other method avoids.
There are several other methods as well; these are the ones that spring
to mind as the most Cocoa-ish. All code written in Mail, standard
