Try: 

 if test $# -ne 2; then  echo wrong.  exit fi  It&#39;s an alternate way of writing the same script and while I haven&#39;t tested it under Nios II Linux, I&#39;m reasonably confident it should work.

/bin/sh is mostly linked to another shell (bash/dash, ...) 

 You need to determine what shell you are running on the Nios II (e.g. hush) and see what you are running on your development machine. Only then can you make a fair comparison since not all shell support (obviously) the same syntax set.

I have the same problems as aqura. (I&#39;m using uClinux 1.4.) When you select "sh" for a new "Nios II Linux Filesystem" project, the information there says that it is indeed bash, so aqura&#39;s script is supposed to work. 

 I think these features of "sh" might just be broken in this release. If anyone has been able to get them to work, please let me know. Alternatively, if anyone knows of a lightweight shell for Nios II uClinux that has working command substitution (i.e. backquoting), then again please let me know.
