for these strings, i wanna remove the ./ for each line

You don't need sed for such a simple task:

cut -c3- file

For completeness, here is the sed command:

sed 's/..//' file
1 Like
4

AWK one

awk -F"/" '{print $2}' urfile
5

sed only ..

  
[root@SKS Shirish]# echo "123 shirish" > a
[root@SKS Shirish]# cat a
123 shirish
[root@SKS Shirish]#  sed -i 's/^.\{2\}//g'   a
[root@SKS Shirish]# cat a
3 shirish
[root@SKS Shirish]#

Hope It will help u bit ...
