bash: /usr/sbinexportfs: cannot execute binary file

Hi everyone!

I step through to the last detail GSG: DM365 DVEVM software Setup for MontaVista Kernel

(http://processors.wiki.ti.com/index.php/GSG:_DM365_DVEVM_Software_Setup)

These first two (2) stages were straightforward and without a problem encountered:

Installing the Target Linux Software

Installing the DVSDK Software

Problem was in the third stage (Creating a Shared File System Between Host and Target).

Here are the details ($ is account user,   # is root user):

Exporting a Shared File System for Target Access

The following shell commands were still alright:

   [root @ -]$    cd /home/roy

   [root @ roy]$   mkdir  -p  workdir/filesys

   [root @ roy]$   cd  DVworkdir/filesys

   [root @ filesys]$   su  root

   [root @ filesys]#   cp  –a  /opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/target/* .

   [root @ filesys]#   chown  –R  roy  opt

   [root @ filesys]#   gedit  /etc/exports

Then I copy/paste to  /etc/exports (which is an empty file) the following line:

/home/roy/workdir/filesys *(rw,no_root_squash,no_all_squash,sync)

Then the problem start with the next shell command:

   [root @ filesys]#   /usr/sbin/exportfs –av

   bash:  /usr/sbin/exportfs:  No such file or directory

I also tried:

   [root @ filesys]#   usr/sbin/exportfs –av

   bash:  /usr/sbin/exportfs:  cannot execute binary file

   [root @ filesys]#   ls  -lsa  usr/sbin/exportfs

   40  –rwxr-xr-x.   1 root  root  39272  Aug 30 2008  usr/sbin/exportfs

I tried doing a ‘man’ for other binaries in filesys, but the textual display

were all encumbered with shaded characters like ^?, ^B^D, ^L, ^E^D^C, ^G ...

As a root, why can’t I execute a binary?  And why can’t I read (‘man’)

any binary in sysfile ??
