递归查找，它将目录名附加到任何文件

Question

Any help would be greatly appreciated!

I need a way to append the parent directory name to any file in any path.

An example current directory tree

/Hawaii/Surfing/800x600/picture1.jpg  
/Hawaii/Surfing/800x600/picture2.jpg  
/Hawaii/Surfing/800x600/picture3.jpg
/RockClimbing/SouthAfrica/TableMountain/4096x2160/Picture1.jpg
/RockClimbing/SouthAfrica/TableMountain/4096x2160/Picture2.jpg
/RockClimbing/SouthAfrica/TableMountain/4096x2160/Picture3.jpg

The goal

/Hawaii/Surfing/800x600/picture1.800x600.jpg  
/Hawaii/Surfing/800x600/picture2.800x600.jpg   
/Hawaii/Surfing/800x600/picture3.800x600.jpg  
/RockClimbing/SouthAfrica/TableMountain/4096x2160/Picture1.4096x2160.jpg
/RockClimbing/SouthAfrica/TableMountain/4096x2160/Picture2.4096x2160.jpg
/RockClimbing/SouthAfrica/TableMountain/4096x2160/Picture3.4096x2160.jpg

I have found some examples of this but the users all have set directory depths unfortunately I have files at many different levels.

find dir -name *.jpg -exec rename -nv -- 's|/(.*)/(.*)$|/$1/$1.jpg|' {}

Your first capture group is matching everything before the last / , not just the last directory name. Use /([^/]*)/ instead of /(.*)/ so it won't match across / delimiters. You're also not splitting up the filename into the name and extension, so you're not inserting the directory name between them.

find dir -name *.jpg -exec rename -nv -- 's|([^/]*)/([^/]*)\.jpg$|$1/$2.$1.jpg|' {} +
