I cant work this out, im sure someone here can...
What I want is for a script to read a number from a file (the file will contain nothing else, just that number) then it increments it by 1 and writes it to the file, this is what I thought it would be...
number=$(cat number) # Get number
number=($("article_number$")+1) # Increment number
echo "$article_number" > number # Write number
Im sure im close, I actually dont know anything about reading from files, I think you do it somthing like that
