How to execute Terminal command from app ?
« on: March 22, 2010, 07:19:59 pm »
Hi all,

Appreciate it if someone could help me out with the following:

I would like to execute a terminal command to unzip a zipfile, just like you do in the Terminal itself:
unzip somefile.zip -d /Tussen

Simply unzipping it by unix.shell('Open somefile.zip') will result in a created directory with the unstuffed files in it, a behaviour that I do not want.

Can this be done with a unix.shell( call? If not, any suggestions?

Thanks,

Jaco

Yes, I know this page.
Might be my limitation, but still have no idea to do what I want to do.....

You might want to use the Shell command from the Unix unit for this task.

You are replaying to a question of 2 and a half years old.

Yes, I was aware of it.

Although I am not sure if the original poster is still interested in this issue I decided to post an answer, as others may search for a solution for the same question, and they would profit from a reply.

First port of call is always the wiki and this subject is pretty well explained over there.
The link Theo posted is all that is required.

Hmmm... this part on the wiki page mentioned before:

Note that the 1.0.x 'Unix.Shell has been deprecated for a while, and is removed in trunk. Use fpsystem.

OK, thanks for the hint. Obviously, I have overlooked this...

The easy thing is that Shell may simply be replaced by fpSystem.
