Let me explain my goal.

Let's say I have a file with a set of paths to files:

/usr/lib32/libssl.so

/usr/lib32/libz.so

...

and so on.

What's an easy way in perl to turn that input into:

/usr/lib32/libssl.so /usr/lib32/libssl.so

/usr/lib32/libz.so /usr/lib32/libz.so

...

Basically duplicate every string to the same line, delimited by a space?

Thanks for any assistance. I use perl's regex regularly for substitutions and the like (instead of using sed) and I prefer PCRE to sed. That said, not familiar with a way to do this.
