Check the permissions on /storage2/program via "ls -l /storage2/program" and make sure the execute bit is set for the user you're trying to run it as. Bash is telling you it's not an executable file. strace doesn't check that--it looks at the "magic number" in the file and sees it as an executable program and runs it. > > > Shawn Hood wrote: > > Try running it along with an strace.
