Code:
bash: echo ${file_path%/*}:bad substitution

That was a good try, but it has a couple syntax errors.
Remove the red `$' and add the red `;'

However, that would display path and file in two different lines.
Modify as:

Code:
for i in `cat filename`
do
    printf "%s %s\n" ${i%/*} ${i##*/}
done
