this question has answer here:

how rename file names? want map names:

i have many files this, mv abc-hdpi.png abc.png not solution.

search prename (perl rename) command; can job easily:

prename 's/-hdpi.png/.png/' *-hdpi.png

failing that:

for file in *-hdpi.png     mv "$file" "${file%-hdpi.png}.png" done
