是否有最快的选项将cp文件从dir1传输到dir2？

Question

i used cp to copy lots of small files (b/n 1M and 10M size; around 6G total) in Linux box. Didn't time it but since i am going to do cp again and again, can time it and be more specific later; but since the cp is not the major task, can't tolerate the time it's taking if there is a better option/choice/way. So, if there is a better way/option/method to do cp -ing (faster) files from one dir to another, be glad glad to try it out.

Thanks,

告诉tar / untar或rsync任何一个，当它们不进行校验和检查时，都会更快，因为它们会批量读取文件，而不是一一对应地处理它们。

Answer 2

Have you tried:

time (cd /usr/local/src/ && tar pcf - cvs.gnome.org) | buffer -m 8m -p 75 | (cd /mnt/tmp/src/ && tar pxf -)

Answer 3

You could try cpio , as that has a copy directory to directory mode.

Answer 4

use perl for fastest copy:

use File::Copy::syscopy;  # preserves OS specific file attributes
copy($foo,$bar) or die "cannot copy $foo to $bar: $!";  # always check for errors!

Try this just backup today's files:

find /home/me/files -ctime 0 -print -exec cp {} /mnt/backup/{} \;
