rsync和(post)进程同步文件。

i like rsync my photos from one (linux) disc partition to an other (backup location) using an shell script. The problem is, that I need to re-scale all photos which are saved on the backup location, for example with mogrify.

我喜欢使用shell脚本将我的照片从一个(linux)磁盘分区复制到另一个(备份位置)。问题是，我需要重新缩放保存在备份位置的所有照片，例如mogrify。

Is it possible to post-process every file, which is synced/copied by rsync? In oder to execute mogrify on every synced file?

是否可以对rsync同步/复制的每个文件进行后处理?在oder中对每个同步文件执行mogrify ?

An other way could using rsync (only) to generate the list of files which have to be synced. Next step: run a loop to mogrify every list entry in order to output the scaled photo to the backup location.

另一种方法可以使用rsync(仅)生成必须同步的文件列表。下一步:运行一个循环来固定每个列表条目，以便将缩放的照片输出到备份位置。

The problem is, that I have to add all the directories and child-directories to keep the original folder structure before saving the photo.

问题是，在保存照片之前，我必须添加所有目录和子目录以保留原始文件夹结构。

Using rsync would handle the folder creation "on the fly".

使用rsync可以动态创建文件夹。

So: is it possible to execute an command on every file synced with rsync?

那么:是否可以对每个与rsync同步的文件执行命令?

rsync has a -i/--itemize-changes flag to output a resume of what it does with each file.

rsync有一个-i/- itemize-changes标志来输出它对每个文件所做的操作。

I suggest you to play a bit with it, I'm seeing it outputs lines like >f+++++++++ file1 for a new file, >f..T...... file1 for an unchanged file, >f.sT...... file1 for an update, etc...

我建议您使用它，我看到它输出的是像>，f++++++++的文件，一个新的文件，>。文件1，未修改的文件，>f.sT…文件1更新，等等…

Having that, you can read this output into a variable, and parse this with grep and cut:

有了它，您就可以将这个输出读入一个变量，然后使用grep和cut解析它:

#!/bin/bash
log=$(rsync -i rsync-client/* rsync-server/)
newFiles=$(echo "$log" | grep '>f+++++++++' | cut -d' ' -f2)
for file in $newFiles
do
    echo "Added file $file"
done
