A quick solution:
Code:
sed 's/   /  -/g'
This won't work fully if the missing items on the end of each line aren't padded with spaces. In that case a slightly cleverer solution will be required

Unless I'm missing some significance with the '65258_space.d' (whatever that is), that looks like it would replace every space with a -, producing the following file:
Code:
04--D--H---
03--C--G--K
02--B-----L
01--A--E--I
---01-02-03-04
?

Hi,

Try this,

sed '/^0/s/ / -/g' filename .


Hi,

Can anybody suggest me how to leave the last line in the substitution.
Requirement is to do substitution in all the lines except the last line.

I tried

sed '!$s/ / -/g' filename ....But its not working ..giving syntax error

Thanks
Penchal
