Let's go, :)

I need simple script :
-------------------------------------------------------------------
old:
fox privious; mv kfile kfile01; fox secundus; mv kfile kfile02; fox
tercius; mv kfile kfile03

===================================================================

a little bit improved:

echo "Gimme:"
read a
read b
read c

fox privious; mv kfile $a; fox secundus; mv kfile $b; fox tercius; mv
kfile $c
----------------------------------------------------------------------

what I want:

only one
read a
                I put kfile01 and I want to script do the rest for
                kfile02, kfile03. Also if I put kfile11 -> kfile12
                kfile13 etc. Incriment $a.

something like, you know...
fox privious; mv kfile $a; fox secundus; mv kfile $a+1; fox tercius; mv
kfile $a+2
