I often have the need to modify a large amount of filenames, and I have often found it easiest to turn to Excel and a simple bash script.
Combine this formula with a sequence number and you have a very easy way to rename a massive amount of files and keep the filenames unique.
=concatenate("cp ",char(34),A1,char(34)," ",char(34),"renamed/", B1,char(34))
cp "oldfilename" "renamed/newfilename"
- Drag that formula down the entire column.
- Copy the column to a text editor and save as rename.sh.
- Open a terminal/console and change to the directory containing the files you wish to rename.
- If you haven't made a directory called renamed, type mkdir renamed.
- Run bash rename.sh
