应该是shell脚本啊~~你用file /usr/X11R6/bin/xdm
file /usr/bin/mdkkdm
查看一下，另外，看一下/etc/X11/prefdm这个文件，和上两个一样。
打开看了都是乱码，应该就是执行程序了
/usr/X11R6/bin/xdm: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), stripped
/usr/bin/mdkkdm: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), stripped
/etc/X11/prefdm倒是shell
