Bash Scripts to rename file name based on nth occurence

Question

I have the below file names:

file-photo01-dfakdj.jpg
file-photo02-bjkadf.jpg
file-photo03-annunioo.jpg
...

How to use rename command or other bash command to rename those file names to:

file-photo01.jpg
file-photo02.jpg
file-photo03.jpg
...

Answer 1

With rename command,

rename 's/-[^-]+\.jpg$/.jpg/' *.jpg

(OR)

With bash one liner,

for file in *.jpg; do mv "$file" "${file%-*}.jpg" ; done

Instead of *.jpg you can specify list of file names which you want to rename.
