Opening Unix executable documents on my Mac

I have a new iMac os v 10.6. I recently received some documents on a CD that has an icon indicating it is a UNIX executable file. (black icon with green letters in the top right that says 'exec'. Is there a way I can open these documents on my Mac?

iMac, Mac OS X (10.6)

These files have a .trm extension. I received them on a CD. I know they are supposed to be audio files. I just don't know what format. When I click 'get info' for the document, it indicates that it is a 'Unix executable file' and the file itself is big, 1.3MB. Are there any applications out there that can read a UNIX execut. file (or a way to convert this file to one that can be read on my Mac.

I recently downloaded several videos from the internet that has an icon indicating it is a UNIX executable file. I couldn't open the file until then I tried to convert it via HandBrake. The first was successful. The problem occurs when i tried to covert another file. It was said no valid source found. What's that supposed to mean? Is there any way I can open this video or convert it on my iMac?

open up terminal

cd /path/to/that/unix/binary

chmod +x file name_of_thebinary

./file name_of_thebinary

post any errors, if still nothing, do the following and post:

ldd file name_of_thatbinary


btw, are you sure that file is a unix binary or is it a bash script? and that binary has it been compiled to run on your architecture?

i did steps as you wrote but it apparently doesn't do any change. When I opened with terminal this is what's written: " -bash: /Users/jesseharwig/Downloads/Folx/Maison.De.Himiko.avi.006: cannot execute binary file"
when I followed your step it was saying something like this: No such file or directory

Here's the situation, these files are .avi videos (as it's written in name&extension field). When i click 'get info' it shows that in the general info the kind of the video is Unix Executable File (black square box with neon green 'exec' writing on the left top corner of the square) and 136.4 MB in size.

I don't want to get technical here so I'll just say that because a file has the "executable" permissions flag set doesn't make it "executable". If these are +video files+ then they need to be played with a video player. Try giving them to the Quicktime player.

Edited Update:
I should have read some of the earlier posts in this thread other than the last two. Other's basically are saying things similar to what I said. Sorry for the redundant post.

The problem is that your computer does not know what kind of file it is, probably because it has no valid extension. In your later post, I notice you refer to a file ending in ".avi.006" - it's the ".006" part that is likely to be the extension, and that's not a valid extension.

If the file is a .avi file, it needs to end in ".avi", and then you'll need an appropriate application to play it. Download a copy of [VLC|http://www.videolan.org/vlc>, which can play pretty much every movie format you're likely to run into.

However, the ".006" at the end of that file is a bit concerning... that could indicate that it's part 6 of a file that has somehow been broken into 6 or more segments. You'll need to contact the creator of that file if simply changing the extension doesn't let you play it.
