Dear cocoa-dev,
I am would like to launch a binary as if I launched it via terminal. I tried
the following but it is not working.
NSTask * myTask = [[NSTask alloc] init];
NSArray * arguments = @[@-c, @-l, @'/usr/bin/pico
/Users/colas/myfile.txt'];
[myTask
From documentation of -[NSTask setArguments:] :
The strings in arguments do not undergo shell expansion, so you do not need to
do special quoting”
I don’t know what they mean by “special”, but anyhow, the ‘ ' you put around
your last argument will be passed to your tool and cause it to fail.

Colas,
Do you want your app to open a Terminal window, in which Pico has opened the
file at /Users/colas/myfile.txt?
If that’s so, I don’t think launching it via NSTask is going to get you
anything.
What is the end result you want to achieve?

OK.
But without the simple quotes, it also fails.
With the quotes, the error is
/bin/bash: pico /Users/colas/myfile.txt: No such file or directory
Without the quotes, the error is
Error opening terminal: unknown.
Thanks!

Terminal doesn't just run the shell (which, in turn, runs pico). It provides a
window and a TTY (terminal device) for the processes to use and translates the
I/O to the window.
Try putting
/usr/bin/pico /Users/colas/myfile.txt
into separate items in the argument NSArray. I find the man page ambiguous,
and I lack direct experience, but that may be what bash expects.
It is not working, unfortunately.
I can’t guarantee that this will solve the larger
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.

NSArray * arguments = @[@-c,

Hi Colas,
Pico is an interactive text editor. I don’t think NSTask is going to give you
much opportunity to interact with it. Are you using Pico as an example, or
are you actually trying to launch Pico?
If you really *are*
Colas,
If my previous code snippet doesn’t work with pdflatex, NSTask has a
-setEnvironment method; it may allow you to set your task’s environment
variables.

I am trying to adapt your code to pdflatex. I hope it will work!!!
It seems that putting the option -l at the end was very important.
Do you know why? I have to admit that I put these « -c » and « -l » options
thanks to other answers, but I don’t know what they are doing.

Using setEnvironment made it easily. I was looking for a complicated solution
when the solution was not so difficult.

I just added iCloud and App Sandboxing entitlements to my app. I had to fix
some code that autosaves a file on launch to Application Support/, so now it
saves inside the Container.
But now I see the very brief flash of what I think is an Open file Panel, set
to some iCloud setting.

Hi All,
I have a question about efficiency when trying to compare NSURL. The
requirement is quite simple. I try and iterate through a directory to all
subdirectories and files. While doing this walk-through, I need to check
against an array of NSURLs which are restricted files and folders.

This doesn’t sound like such a good idea. There’s nothing to guarantee that
your saved data will actually match the state of the file system the next time
