Bulk Rename Files in Ubuntu / Linux

If you have a lot of files to be renamed, it will waste you time to rename files manually (for example, change file names from camera). If you want to change the capital or uppercase files name to lowercase, you can do the following command in your terminal in the current directory,

ls | while read upName; do loName=`echo "${upName}" | tr '[:upper:]' '[:lower:]'`; mv "$upName" "$loName"; done

But, if you want to change file names, find and replace, or others, I suggest you to install thunar

sudo apt-get install thunar

And then use the bulk rename program from thunar as shown in the following screenshot. You can insert date / time, insert / overwrite, search and replace, numbering and also uppercase / lower case. Let's try!
