Current student @ Edinburgh Napier University and struggling slightly with renaming duplicate files for archiving

i already have the script with duplicate files matching md5 and sorting by filename, then outputting to a .txt file


stage 2 of the project has to copy over files only named in the IMG_1234.jpg format
so IMG_xxxx.jpg must be 4 numbers after the "_" and all in jpg format


my problem is,when copying over the IMG_ files, if there is an IMG_ file with the same name in that directory, the one being copied must be renamed.

renamed by added .jpg to the end : so IMG_6453.jpg would become IMG_6453.jpg.jpg

Help?

Thanks

Yep. The coreutils support the --backup parameter, and you can use that in conjunction with --suffix to do what you want.

See here for usage: http://www.gnu.org/software/coreutil...Backup-options

You didn't mention what you were using to copy the files, so I assumed you were using 'cp' itself.

yes i use the cp command

im new to linux as of september and struggling to find information that i understand

this is for my university coursework and can only use the CLI on Puppylinux. this eliminates the use of tools such as Fdupes

but thanks

I am ready to help you, set questions. Together we can find the decision.

That link will take you to the EXACT thing you are asking for, so I don't know why you are talking about Fdupes and dismissing my post.

It says to use 'cp' with --backup and --suffix and gives you an explanation of how to do so. Do you have a question about it? Have you tried it?
