Command Not Found??

Super TWiT · 06-06-2010, 06:56 AM

When I try to execute this:

Code:

magic=0x1234 j=0 for i in `sed -e '1,2d' /media/disk/Other/Network\ Card/original-rom | cut -c 9- | tr -d "\n"` do echo ethtool -E eth0 magic $magic offset 0x$(printf %x ${j}) value 0x${i} j=$(($j + 1)) done

I get a command not found error. It's an ethtool script I found online. I am using it to reprogram my ethernet controller as it is having corrupt firmware issues. I have ethtool installed, so I am not sure what the problem is. It's probably something simple.---

The ethtool executable is usually installed in /sbin (which is not in user's PATH) since it is an administrative tool. I don't think it works as a normal user, hence you have to acquire root's privileges to run this command. If it is not installed in the standard place for some reasons, you can invoke it by specifying the full absolute path. Hope this helps.

Oh, should have mentioned that I tried executing it as root too.

Sorry, I was just too focused on ethtool you did mention in the question and I didn't notice that you missed some command separator in your line. First, we cannot define a variable in that way before a for loop (only before commands) but we have to put the assignment on its own line. Second an inline for loop must have semi-colon before the do and done keywords. Something like this should do the trick:

Code:

magic=0x1234 ; j=0 ; for i in `sed -e '1,2d' /media/disk/Other/Network\ Card/original-rom | cut -c 9- | tr -d "\n"` ; do echo ethtool -E eth0 magic $magic offset 0x$(printf %x ${j}) value 0x${i} j=$(($j + 1)) ; done

The way it is posted, I would not expect anything to work. Please edit your post with newlines as required---the format should be something like this:

Code:

magic=0x1234
j=0
for i in <command string>; do
     <command(s)>
done

**

Try running ethtool by itself.

You CAN have all this on one line, but it needs to have ";" whereever there would normally be a newline.

Hey colucix I tried what you wrote above, and it looked like it worked (it echoed things to the command line) but when I compared the image dump from my ethernet card, nothing changed. I was root when I ran everything. I am not blaming you, it was the site I got it from. Any ideas? The site is here.
