For example, in the folder with ODF and TXT files, you need to delete all TXT files without affecting ODF. It's not very convenient to do this in file managers, but here the console saves us because we don't have to search for the files we need by extension, but just execute the following command: rm -R path to the folder * .txt For example: rm -R /home/max/1/*.txt Or any other file extension to be removed.
