sed command problem
hi
I am using "sed" command to find and replace a text in a file.
if the searched string is in the last line with no newline character in the end, it doesn't retrive this line. What is the solution to this?
i am using sed as:
sed -e "s/abc/ABC/g" test.txt
where i am replacing abc with ABC
