Sounds like you don t have the execute flag set on the file permissions  try    chmod u x program name

Try this   sudo chmod  x program name   program name

chmod u x program name  Then execute it   If that does not work  copy the program from the USB device to a native volume on the system  Then chmod u x program name on the local copy and execute that   Unix and Unix-like systems generally will not execute a program unless it is marked with permission to execute  The way you copied the file from one system to another  or mounted an external volume  may have turned off execute permission  as a safety feature   The command chmod u x name adds permission for the user that owns the file to execute it   That command only changes the permissions associated with the file  it does not change the security controls associated with the entire volume  If it is security controls on the volume that are interfering with execution  for example  a noexec option may be specified for a volume in the Unix fstab file  which says not to allow execute permission for files on the volume   then you can remount the volume with options to allow execution  However  copying the file to a local volume may be a quicker and easier solution

[bash] Ubuntu says "bash: ./program Permission denied"
