将多个目录中相同类型的所有文件移到一个文件夹中

Question

我在一个文件夹中有大约2000个子文件夹，在每个文件夹中都有.pdf个文件。我需要一个unix命令，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/。如果您要移动它们，请将cp替换为mv。
