Shell – Find and rename files adding part of the path to filename

renameshell-script

I have a folder with two level of subfolders inside it. Inside the second subfolder, there is a jpg file. All the jpg have the same name: cover.jpg

Example:

/home/user/folder001/folderAAA/cover.jpg
/home/user/folder002/folderBBB/cover.jpg
[...]
/home/user/folder999/folderZZZ/cover.jpg

I need to find (and copy to a new folder) all cover.jpg files and rename them adding to its filename (as prefix) the name of the first and second subfolder.

Example:
After the intended operation, the content ot /home/user1/newfolder must be:

folder001_folderAAA_cover.jpg
folder002_folderBBB_cover.jpg
[...]
folder999_folderZZZ_cover.jpg

#! /bin/bash

target_dir_path="/copy/here"

for file in folder*/*/*.jpg; do
        l1="${file%%/*}"
        l2="${file#*/}"
        l2="${l2%%/*}"
        filename="${file##*/}"
        target_file_name="${l1}_${l2}_${filename}"
        echo cp "$file" "${target_dir_path}/${target_file_name}"
done

Remove the echo if it does what you want.

Bash – For each subfolder, sort files by name and rename them to sequential padded numbers (regardless of extension)

for dir in */*; do           # loop over the directories
    (                        # run in a subshell ...
        cd "$dir"            # ... so we don't have to cd back
        files=(*)            # store the filenames in a zero-indexed array

        for index in "${!files[@]}"; do
            file=${files[$index]}
            ext=${file##*.}
            newname=$(printf "%02d.%s" $((index+1)) "$ext")
            mv "$file" "$newname"
        done
    )
done

Suppose you have a file with no extension. In that case it will have the same name except with leading numbers (e.g. my_file => 05.my_file)

All non-hidden directory entries will be renamed, including directories.

Renaming files with its path name

I would use the mcp tool from the mmv ("multiple move") package for that:

mcp '/home/user/*/*/Load.bdf' '#1_#2_Load.bdf'

The #1, #2 etc. in the second string will be replaced by the contents of the corresponding 1st, 2nd etc. wildcard from the first string. Note that the path is in single quotes so that the wildcards are interpreted by mcp, not by the shell.

With the command shown, the files will be copied to the current directory. If you replace mcp with mmv, the files will be moved instead.
