What do you mean with field?
how about
Code:
echo "$field" >> "$file"

Do you mean you need an empty line at the end of the file? In this case try:
Code:
echo >> file

else please describe "new field" better.

If your file looks like this:
Code:
12 23
12
23
35

A simple echo 100 >> file would do the thing, otherwise you could try this:
Code:
sed 's/35/35\
100/' file

Now I see this is not "your" thread! This is called thread/topic-hijacking and should be avoided. Why did you not open your own thread?
