Execute Commands in the Linux Commandline [Lazarus / Free Pascal]

I have a problem. I want to execute some commands in the Commandline of linux. I tested TProcess (So i am using Lazarus) but now when i am starting the programm, there is nothing, wich the Program do.

Here is my Code:

uses [...], unix, process;
[...]
var LE_Path: TLabeledEdit;
[...]

Pro1:=TProcess.Create(nil);
Pro1.CommandLine:=(('sudo open'+LE_Path.Text));
Pro1.Options := Pro1.Options;  //Here i used Options before
Pro1.Execute;

With this Program, i want to open Files with sudo (The Programm is running on the User Interface)

->Sorry for my Bad English; Sorry for fails in the Question: I am using StackOverflow the first time.

I guess the solution was a missing space char?

Change 

Pro1.CommandLine:=(('sudo open'+LE_Path.Text));

to

Pro1.CommandLine:=(('sudo open '+LE_Path.Text));
# ----------------------------^--- added this space char.

But if you're a beginner programmer, my other comments are still worth considering:

  1. trying to use sudo in your first bit of code may be adding a whole extra set of problems. SO... Get something easier to work first, maybe

    /bin/ls -l /path/to/some/dir/that/has/only/a/few/files.

  2. find out how to print a statement that will be executed. This is the most basic form of debugging and any language should support that.

  3. Your english communicated your problem well enough, and by including sample code and reasonable (not perfect) problem description "we" were able to help you. In general, a good question contains the fewest number of steps to re-create the problem. OR, if you're trying to manipulate data,

    a. small sample input, b. sample output from that same input c. your "best" code you have tried d. your current output e. your thoughts about why it is not working AND comments to indicate generally other things you have tried.
