It does. Cam tried to invoke the program with $ primafax_l.bin but bash complained that it could not find the file: bash: primafax_l.bin: command not found He then tried to give it as an argument to a separate instance of bash... $ sh primafax_l.bin which tried to interpret it as a shell script and found that it was not shell script... primafax_l.bin: primafax_l.bin: cannot execute binary file so then he used strace... $ strace sh primafax_l.bin which simply told him the same thing in more detail. The behavior of the first token on a bash commandline is different than its behavior when provided as the argument to an instance of bash... bash interprets the _argument_ as a normal path to a script file... which amounts to allowing invocation of shell scripts in the current directory. When provided as the first token on a commandline, bash is more cautious if no slashes are present. --------------------------------------------------------------------------- Jeff Newmiller The ..... .....
