I have a question concerning the renaming 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 Shell scripting, but maybe there is a one liner for the terminal.

  • rename 's/^/1_/' * for renaming all files in the current directory


  • rename 's/^/1_/' DATASET* for renaming all files in the current directory starting with DATASET in their name

Explanation: the expression s/^/1_/ says: "replace the beginning of the filename (that means this symbol -> ^)' with 1_".

If your rename doesn't do this out of the box, you need to install prename (PERL rename). – user1359 Jan 15 at 0:51

You can use pyRenamer. It can be found in the Ubuntu software center. enter image description here The original file pattern should be {X} and the renamed file pattern should be 1_{1}

You can easily rename all the files in current directory typing (assuming you are using bash):

for i in *; do mv $i 1_$i; done

obviously take it with care; it will remane ALL the files in the current directory that are 'visible' (filename not starting with a '.')

Very easily to rename all the files in the current directory you can type (assuming you are using bash):

sample example

1st File name BookOFAmit.txt
2nd File name BookOFAmit1.txt and so on
want to change it to The_GREAT_BookOFAmit.txt_20150119 and The_GREAT_BookOFAmit1.txt_20150119

for i in *; do mv $i The_GREAT_BookOFAmit.$i_20150119;done
