Not sure if I like the format ;-)
$ fincore /etc/fstab /bin/emacs
1 1544 /etc/fstab
4156 17163144 /bin/emacs
Why we need file size there? Would be better to use filename as the
first column?
$ fincore /etc/fstab /bin/emacs
/etc/fstab 1
/bin/emacs 4156
it would be also nice have a way how to print only the number if only one
file specified. Then you can use it in scripts without awk (or so),
just:
FILEPAGES=$(fincore /bin/emacs)
