Bash：对于文件中的每一行，设置变量

Question

I am trying to iterate through a text file, and set a variable once for each line.

I am having trouble doing so. I have simplified the process so that it is just echoing the result. There would be more going one, but this part of the widget is not working correctly.

while read p; do
   set $FN=`echo $p`
   echo $FN
done <file.txt

When I don't use set, it looks like it is trying to echo a file called the contents of $p.

I am using echo $p to send the line to a series of cuts, to get the data I want.

I know I am doing something fundamentally wrong, just not sure what that might be.

Answer 1

This works for me. Just say "FN=" without the "set

while read p; do
  FN=$p
  echo $FN
done < test.list
