I have a question concerning the renamining of multiple files in a folder. For about 200 files I would like to add the String "1_" to the beginning of all filenames. The filenames are for example "DATASET_X_Y_Z" and the result should be "1_DATASET_X_Y_Z". Maybe somebody knows how to do this the easy way. Unfortunately I don't know a thing about Shellscripting but maybe there is a oneliner for the terminal.
