using perl we can do.

perl -p -i -e "s/n/abc/g" file_name

We can replace n characters by using the following command:
1,$s/./xyz/g
where 1 shows that the search string will start searching patterns from first line of the file.
           '.' for any character.
            g for global replacement.

sed  -i  's/<Search_word>/<Replacing_word>/g'   <filename>

sed -i option will directly changed in the fine. no need to redirect the output and create the another file. Here "g" for globe change.

All the sed replacements are by default global. It's in the vi editor that you have to specifically give "g" for global replacement.

you dont need /g at the end for removing only the nth occurrence. You need g for replacing globally. The answer is:
sed s/string_to_replace/string_to_replace_with/n file_name
where "n" is the position where you want to do the replacement.
