file - 将多个目录中相同类型的所有文件上移一个文件夹

Question

我在一个文件夹中有大约 2000 个子文件夹，每个文件夹中都有 .pdf 文件。我需要一个 unix 命令，它将所有这些文件移到一个文件夹中。

Answer 1

$ cd thefolder # which contains the subfolders and where the PDFs should land
$ find . -name *.pdf | xargs -I {} cp -iv {} .

# find all files
# which end in .pdf
# recursively from
# the current folder
#                    |
#                      for each emitted line
#                      copy the output (captured by {}) to 
#                      the specified path ('.' is the current directory)
#                      copy should be verbose and should ask,
#                      in case a file would be overwritten

这应该将您的文件复制到 /thefolder/。如果要移动它们，请将 cp 替换为 mv。
