How can I make a progress bar while copying a directory with cp?
提问by octosquidopus
I suppose I could compare the number of files in the source directory to the number of files in the target directory as cp progresses, or perhaps do it with folder size instead? I tried to find examples, but all bash progress bars seem to be written for copying single files. I want to copy a bunch of files (or a directory, if the former is not possible).
我想我可以在 cp 进行时将源目录中的文件数与目标目录中的文件数进行比较，或者用文件夹大小来代替？我试图找到示例，但所有 bash 进度条似乎都是为复制单个文件而编写的。我想复制一堆文件（或一个目录，如果前者不可能）。

You can also use rsyncinstead of cplike this:
您也可以使用rsync代替cp这样的：
rsync -Pa source destination
rsync -Pa source destination
Which will give you a progress bar and estimated time of completion. Very handy.
这将为您提供进度条和预计完成时间。非常便利。

To show a progress bar while doing a recursive copy of files & folders & subfolders (including links and file attributes), you can use gcp(easily installed in Ubuntu and Debian by running "sudo apt-get install gcp"):
要在递归复制文件、文件夹和子文件夹（包括链接和文件属性）时显示进度条，您可以使用gcp（通过运行“sudo apt-get install gcp”轻松安装在 Ubuntu 和 Debian 中）：
gcp -rf SRC DEST
Here is the typical output while copying a large folder of files:
这是复制大型文件文件夹时的典型输出：
Copying 1.33 GiB 73% |##################### | 230.19 M/s ETA: 00:00:07
Notice that it shows just one progress bar for the whole operation, whereas if you want a single progress bar per file, you can use rsync:
请注意，它仅显示整个操作的一个进度条，而如果您希望每个文件有一个进度条，则可以使用rsync：
rsync -ah --progress SRC DEST

You may have a look at the tool vcp. Thats a simple copy tool with two progress bars: One for the current file, and one for overall.
你可以看看这个工具vcp。这是一个带有两个进度条的简单复制工具：一个用于当前文件，一个用于整体。

Here another solution: Use the tool bar
这是另一个解决方案：使用该工具 bar
You could invoke it like this:
你可以这样调用它：
#!/bin/bash
filesize=$(du -sb | awk '{ print }')
tar -cf - -C ./ | bar --size ${filesize} | tar -xf - -C
You have to go the way over tar, and it will be inaccurate on small files. Also you must take care that the target directory exists. But it is a way.
你必须绕过 tar，它在小文件上会不准确。此外，您必须注意目标目录是否存在。但这是一种方式。

A simple unixway is to go to the destination directory and do watch -n 5 du -s. Perhaps make it more pretty by showing as a bar . This can help in environments where you have just the standard unix utils and no scope of installing additional files . du-sh is the key , watch is to just do every 5 seconds.
Pros: Works on any unix system Cons: No Progress Bar
一个简单的 unix方法是转到目标目录并执行watch -n 5 du -s. 也许通过显示为条形来使其更漂亮。这在您只有标准 unix 实用程序而没有安装附加文件范围的环境中会有所帮助。du-sh 是关键， watch 就是每 5 秒做一次。
优点：适用于任何 unix 系统 缺点：没有进度条

My preferred option is Advanced Copy, as it uses the original cpsource files.
我的首选选项是Advanced Copy，因为它使用原始cp源文件。
$ wget http://ftp.gnu.org/gnu/coreutils/coreutils-8.21.tar.xz
$ tar xvJf coreutils-8.21.tar.xz
$ cd coreutils-8.21/
$ wget --no-check-certificate https://raw.githubusercontent.com/atdt/advcpmv/master/advcpmv-0.5-8.21.patch
$ patch -p1 -i advcpmv-0.5-8.21.patch
$ ./configure
$ make
The new programs are now located in src/cp and src/mv. You may choose to replace your existing commands:
新程序现在位于 src/cp 和 src/mv 中。您可以选择替换现有命令：
$ sudo cp src/cp /usr/local/bin/cp
$ sudo cp src/mv /usr/local/bin/mv

How about something like
怎么样的东西
find . -type f | pv -s $(find . -type f | wc -c) | xargs -i cp {} --parents /DEST/$(dirname {})
It finds all the files in the current directory, pipes that through PV while giving PV an estimated size so the progress meter works and then piping that to a CP command with the --parents flag so the DEST path matches the SRC path.
它查找当前目录中的所有文件，通过 PV 将这些文件通过 PV 进行管道传输，同时为 PV 提供估计的大小，以便进度表正常工作，然后将其传输到带有 --parents 标志的 CP 命令，以便 DEST 路径与 SRC 路径匹配。
One problem I have yet to overcome is that if you issue this command
我尚未克服的一个问题是，如果您发出此命令
find /home/user/test -type f | pv -s $(find . -type f | wc -c) | xargs -i cp {} --parents /www/test/$(dirname {})
the destination path becomes /www/test/home/user/test/....FILES... and I am unsure how to tell the command to get rid of the '/home/user/test' part. That why I have to run it from inside the SRC directory.
目标路径变为 /www/test/home/user/test/....FILES... 并且我不确定如何告诉命令摆脱“/home/user/test”部分。这就是为什么我必须从 SRC 目录中运行它的原因。
