[oclug] filename renaming

[Bart Trojanowski]

The regexp here looks quite illegible. How about...

(
cd Pictures
for jpg in */*.jpg ; do
    dir="$(dirname "$jpg")"
    name="$(basename "$jpg")"
    mv "$jpg" "$dir/${dir}_$name"
done
)

As an added bonus this will work with any characters in the file name.

Another way of doing the same thing in just shell...

(
cd Pictures
for jpg in */*.jpg ; do
    dir="${x%/*}"
    name="${x##*/}"
    mv "$jpg" "$dir/${dir}_$name"
done
)

... but that's getting back to the same problem the sed had.
