foreach command

Hi,

Thanks for your reply. The code does what I require but I will be changing file.txt with different values for var1 and var2. Also, instead of

Code:

echo "var1 = " $a
echo "var2 = " $b

I will be running processes which require the variables given. This is why I was using the foreach command. I don't think I can use the code that you supplied for this purpose. Sorry if this doesn't make sense. Let me know if I need to explain it clearer,

Simon
