I have encountered one problem when I tried to use software I have copied from a windows machine in a windows emulator. The filenames where all in capital letters most windows programm╪≈¬we5»1q·äó)┼%Auntil I have renamed them all. Instaed of renaming each file with one seperate "mv" command you can use this little, useful script

for i in *
do mv -i $i $(echo $i | tr [A-Z] [a-z])
done
