Post not marked as liked A: I don't really know what you're trying to do, but this command will remove all files and folders with the.bat extension from the current directory: rm -i *.bat It does remove all files and folders with the.bat extension (regardless of the extension name). However, in the absence of any other arguments, it will remove all files in the current directory with.bat in the name.
