GUYs one problem..
My Box is SunOS .. Whereas all the command runs fine in AIX but it throws error in SunOS (except the perl one)..

But i will really like to use the awk command or anything instead of Perl..

Could anyone gives me the command which will work in SunOS..

Try POSIX awk (/usr/xpg4/bin/awk) on SunOS.

Another awk one:

t$ cat file
record one

record two

record three

$ awk -v RS="\n\n" -v ORS="\n" 1 file
record one

record two

record three

But honestly, as already mentioned above, cat -s is easier.
