该文件存在，如此命令所示：
lol@foldingmachine:~/Downloads/d3linux$ dir -alh
total 431M
drwxr-xr-x 6 lol lol 4.0K Jul 12 15:27 .
drwxr-xr-x 225 lol users 36K Jul 9 02:53 ..
# ...
-rwxr-xr-x 1 lol lol 3.3M Aug 26 2005 descent3
# ...
和这一个：
lol@foldingmachine:~/Downloads/d3linux$ file ./descent3
./descent3: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux.so.2, for GNU/Linux 2.0.0, stripped, too many notes (256)
但是当我尝试执行它时，我看到以下消息：
lol@foldingmachine:~/Downloads/d3linux$ ./descent3
bash: ./descent3: No such file or directory
是什么给出了？
