Hi All
I need a small help for the below format in making a small script in Perl or Shell.

I have a file in which a single line entries are broken into three line entries.
Eg:
I have a
pen and
notebook.

All i want is to capture in a single line in a separate file.
eg: I have a pen and notebook.

Thanks in Advance for your help.

Regards
Kalaiela

$ while read a; do echo -n "$a "; done < input.txt
