Hi, How do I insert character (e.g. , or .) at certain positions in a line? For example I want to insert a period ( . ) after the first 4 characters of every each line in the file. I cannot do it in sed command. I'm playing with my script using perl command but to no avail. Please advice. Thanks in advance. See below: Input: 
12345
67890
23456
78901
34567

Desired Output: 
1234.5
6789.0
2345.6
7890.1
3456.7
