Can any one help me in writing a shell script to open a file , insert a
number after the given position .
For Example : my file file.sh contains
1:H001:10:400:500:20:30
2:H002:30:600:700:40:50
3:H003:40:800:900:50:60
I want to insert zero after the position 4th in all the
rows , the final file should be like this .
file.sh
1:H001:10:400:0:500:20:30
2:H002:30:600:0:700:40:50
3:H003:40:800:0:900:50:60
