title: Bulk renaming files in Android Asset Studio download tags: android,unix-xargs
If you use Roman Nurik's wonderful Android Asset Studio, you'll get a downloaded zip of differently sized icons.
You may want to rename these files from ic_launcher.png to something else - otherwise it may clash with an existing file of that name.
You can use xargs to do this. Move to the directory of the downloaded file, in the res directory and run this:
ls | xargs -I {} mv {}ic_launcher.png {}YOUR_NEW_FILENAME.png
We list each mipmap-xxxx directory, and rename all the ic_launcher.png files within to our new filename.
