GODhack,
From the file name extension of exe. Its a windows program. Therefore you need to run it in WINE or something like that.
It should run from FAT but as you have discovered, FAT does not support Linux permisions, so you have to fake them at mount time.

Nooo....
[vytautas@VytoPC Warsow0.5]$ ./warsow.x86_64 !!!

Hmmm interesting as you see I added some options and now it looks like rwx still something wrong?
>maybe it's mounted with noexec option?
| Code: |
[root@VytoPC ~]# cat /etc/fstab |grep vfat
/dev/sda4 /media/disk vfat user,rw,umask=000,uid=vytautas,gid=vytautas 0 0

| Run the mount command to see what are the mount options in effect. It's possible Linux mounts foreign filesystems with noexec by default. |

You are right:
| Code: |
/dev/sda4 on /media/disk type vfat (rw,noexec,nosuid,nodev,umask=000,uid=500,gid=500)

Why did you cat the file, then grep it? Just do
| Code: |
grep vfat /etc/fstab

Indeed, there is much too much cat grepping going on.
Not to mention all the superfluous cat awking and cat seding.  |
