Is this the entire input file?

For an example I have just given two lines. But in reality my input file consists of 100's of lines.

Is there way to acheive my need using SED or AWK?

If awk is acceptable:

awk 'NR==1{x=$0;next}NF{x=x","$0}END{print x}' filename

Use nawk or /usr/xpg4/bin/awk on Solaris.

if sed,
sed -e :a -e N -e 's/\n/,/' -e ta yourfile.txt >newfile.txt
