How to execute NIOS II Command Shell commands from a *.bat file

--- Quote Start ---

"sh -c <command> [args]" might work a bit better.

Most "bourne-like" shells behave this way. Since the Nios II shell environment is based on Bash ("Bourne Again SHell"), this should work.

You don't need 'sh -c' here, that is usually only needed when you need a shell to do filename globbing or stdin/stdout redirection when a program is running something using one of the exec family of functions - eg execl().

dsl,

I'll admit my knowledge of shell files started yesterday, so I have taken your advice.

slacker,

I tried a few variations of "sh -c <command> [args]" and it does not work, I cannot get the "Nios II Command Shell.bat" to execute arguments when it is started. I am thinking this is a problem with 9.1.

Thanks

This isn't a problem only with 9.1, as I'm in 11.1sp1 and I can't do it either. Being able to auto-execute .sh scripts from my sim and build environments would help streamline things quite a bit, and reduce the amount of user interaction required.

If ANYONE knows how to automatically run a script at the NIOS shell, it would be greatly greatly appreciated!

The command shell will autorun the script file user.bashrc, so you can use this to make it work.

My batch file and script file are in a previous post. The batch file renames my script file to user.bashrc so it is autorun and starts the command shell. To prevent the script from running every time the command shell is opened, the last thing the script should do is delete itself.

It would be nice if arguments worked, but this method has worked for me.

I do the following:

I put all commands in a shell script, then I execute a wrapper bat file.

alt_win.cmd

@echo off
mode con lines=32766
setlocal enabledelayedexpansion
SET myPwd=%CD%
:: 64-bit / 32-bit OS detection
SET binName=bin
if "%PROCESSOR_ARCHITECTURE%"=="AMD64" SET binName=bin64
if "%QUARTUS_ROOTDIR%"=="" echo Env Var QUARTUS_ROOTDIR is missing. Is Quatrus installed? Is the path set correctly & exit /b 1
SET QUARTUS_BINDIR=%QUARTUS_ROOTDIR%\%binName%
SET PATH=%PATH%;%QUARTUS_BINDIR%
for /f "delims=" %%a in ('%SOPC_KIT_NIOS2%\bin\cygpath\cygpath.exe %myPwd%') do @set myCygPwd=%%a
::echo %myCygPwd%
%SOPC_KIT_NIOS2%\"Nios II Command Shell.bat" %myCygPwd%/%*

example.bat

@echo off
alt_win.cmd %~n0.sh %*

example.sh

# !/usr/bin/env bash
--SNIP--
cmd="quartus_pgm -c $uCable -m jtag -o ipv;$binDir/$flashFile"
echo " Running \"$cmd\""
$cmd || {
	echo -e "\e quartus_pgm failed. \e[0m"
	exitFunc 1
}
--SNIP

Using this methods allows you to have a unified interface to Windows and GNU/Linux. Windows users will double click on the example.bat file or even run it from cmd (with parameters and all) and GNU/Linux users will run the example.sh shell script as usual.
