I have some assets that my designer have created, he branched them correctly making all dpi's match their directories so I was happy because I didn't had to copy those files to each subfolder but when I checked out their names they had dashes in the filenames, which made android compiler to fail.
So how I can make a bash script to rename all files below drawable-*, to the same file name but replacing dashes with underscores?
Example:
Convert this :
drawable-hdpi/
my-icon.png
my-icon-2.png
drawable-xhdpi/
my-icon.png
my-icon-2.png
drawable-xxhdpi/
my-icon.png
my-icon-2.png
To this:
drawable-hdpi/
my_icon.png
my_icon_2.png
drawable-xhdpi/
my_icon.png
my_icon_2.png
drawable-xxhdpi/
my_icon.png
my_icon_2.png
