请在目录（递归）的所有文件的符号链接到其他目录

Question

我在文件夹中的文件：

folder_a/ 
    subfolder_1/ 
    file.txt 
    subfolder_2/ 
    subfolder_3 
     file2.txt 
    file3.txt 

我需要符号链接改为.txt，文件到folder_b：

folder_b/ 
    000_file.txt ---> folder_a/subfolder_1/file.txt 
    001_file2.txt ---> folder_a/subfolder_2/subfolder_3/file2.txt 
    003_file3.txt ---> folder_a/file3.txt 

Answer 1

灿与Ruby脚本做到这一点：

src = '/path/to/folder_a/' 
dst = '/path/to/folder_b/' 

files = `find $(realpath #{src}) -type f -iname "*.txt"`.split("\n") 
files.each_with_index do |path, idx| 
    name = File.basename path 
    `ln -s "#{path}" "#{dst + "%03d" % idx}__#{name}"` 
end 

Answer 2

在bash：

shopt -s globstar     # Enable **/* glob 

for fname in folder_a/**/*.txt; do # Get all .txt in folder_a 
    bname=${fname##*/}    # Basename of link target 

    # Assemble link name 
    printf -v lname '%s%03d%s' 'folder_b/' "${bname//[!0-9]}" "_$bname" 

    # Create link 
    ln -s "$fname" "$lname" 
done 

导致
