batch rename files with ids intact

Question

i have a directory listing like

seascaperecovered0088crop.jpg 
seascaperecovered0096crop.jpg
seascaperecovered0098crop.jpg
seascaperecovered0101crop.jpg
seascape         


        

Answer 1

With bash regular expressions

for file in *; do 
  [[ "$file" =~ [0-9]+ ]] && mv "$file" seascape_${BASH_REMATCH[0]}.jpg 
done

Answer 2

Very straightforward:

for i in seascaperecovered*.jpg; do A=${i/crop/}; mv $i ${A/recovered/_}; done

(Put echo before the mv first for a dry run.)
