I'm searching for a find command to copy all wallpaper files that look like this:

3245x2324.png (All Numbers are just a placeholder) 3242x3242.jpg

I'm in my /usr/share/wallpapers folder and there are many sub folders with the files I want to copy. There are many like "screenshot.png" and these files I don't want to copy.

My find command is like this:

find . -type f -name "*????x????.???"

If I search with this I get the files I wanted to see, but if I combine this with -exec cp:

find . -type f -name "*????x????.???" -exec cp "{}" /home/mine/Pictures/WP \;

the find command only copies 10 files and there are 77 (I counted with wc).

Does anyone know what I'm doing wrong?

CodePudding user response：

You can look it up if you follow the link. renaming with find You can use -exec to do this. But i'm not sure you can do rename and copy in one take.Maybe with a script that got executed after every find result.

But that's only a suggestion.

CodePudding user response：

One idea/approach is to copy absolute path of the file in question to the destination, but replace the / with an underscore _ since / is not allowed in file names, at least in a Unix like environment.

With find and bash, Something like.

find /usr/share/wallpapers -type f -name "*????x????.???" -exec bash -c '
   destination=/home/mine/Pictures/WP/
   shift
   for f; do
     path_name=${f%/*}
     file_name=${f##*/}
     echo cp -vi "$f" "$destination${path_name//\//_}$file_name"
   done' _ {}  

• See understanding-the-exec-option-of-find

With globstar nullglob shell option and Associative array from the bash shell to avoid the duplicate filenames.

#!/usr/bin/env bash

shopt -s globstar nullglob
pics=(/usr/share/wallpapers/**/????x????.???)
shopt -u globstar nullglob

declare -A dups
destination=/home/mine/Pictures/WP/

for i in "${pics[@]}"; do
  ((!dups["${i##*/}"]  )) &&
  echo cp -vi "$i"  "$destination"
done

• GNU cp(1) has the -u flag/option which might come in handy along the way.
• Remove the echo if you're satisfied with the result.
