折腾：
【已解决】Mac中mv移动文件的逻辑和如何实现中断后继续即断点续传
期间，已经参考：
而直到了：
rsync时，想要查看到整体的进度，可以通过：
–info=progress2
但是这个参数的具体含义是什么，需要去研究清楚。
即用之前，还是先去搞清楚rsync更多的参数和用法

其中：
- -a, –archive archive mode; same as -rlptgoD (no -H)
- 此处完全忽略不考虑文件的各种属性，比如时间等等，所以可以不用-a
- -n, –dry-run show what would have been transferred
- 暂时也不用
- –remove-source-files sender removes synchronized files (non-dirs)
- 此处为了安全，暂时还是不用这个 删除源文件 的选项了
- 等同步完成后，再去手动删除源文件就好
- –info=progress2
- 没找到这个选项啊
rsync –info
3.1.0版本后，才有 –info
而此处Mac中的rsync是：
rsync version 2.6.9 protocol version 29
所以要去mac中升级rsync：
【已解决】Mac中通过brew升级rsync
看了看新版本的help中，果然有info参数：
➜ output rsync --help rsync version 3.1.3 protocol version 31 --info=FLAGS fine-grained informational verbosity
不过没有找到progress2
mac rsync progress2
rsync progress2
sync – rsync –info=progress2 percent complete of copying a large directory is non-uniform? – Ask Ubuntu
没找到解释，发现是：
解释了参数含义：
rsync
“–info=FLAGS
This option lets you have fine-grained control over the information output you want to see. An individual flag name may be followed by a level number, with 0 meaning to silence that output, 1 being the default output level, and higher numbers increasing the output of that flag (for those that support higher levels). Use –info=help to see all the available flag names, what they output, and what flag names are added for each increase in the verbose level. Some examples:
rsync -a –info=progress2 src/ dest/
rsync -avv –info=stats2,misc1,flist0 src/ dest/
Note that –info=name’s output is affected by the –out-format and –itemize-changes (-i) options. See those options for more information on what is output and when.
This option was added to 3.1.0, so an older rsync on the server side might reject your attempts at fine-grained control (if one or more flags needed to be send to the server and the server was too old to understand them). See also the “max verbosity” caveat above when dealing with a daemon.”
【总结】
rsync中，想要显示进度的话：
- 对于每个文件，其进度显示，可以用 –progress
- 但是对于整体的进度，之前是不支持的
- 新版本3.1.0之后支持了，参数是：–info=progress2
- –info：用于显示（更加详细的）信息（实现更细粒度的控制）
- 后面的值的格式是：参数名+数字
- progress2：
- progress：表示显示进度方面的信息
- 2：表示显示整体的进度
- 0：表示silence -》不显示进度
- 1：表示默认default输出的信息
- 2：表示更高一级的显示
- 此处指的是就是 全局的，整体的，进度的信息显示
而–info其他还支持哪些参数，可以通过：
rsync –info=help
而看到：
➜ output rsync --info=help Use OPT or OPT1 for level 1 output, OPT2 for level 2, etc.; OPT0 silences. BACKUP Mention files backed up COPY Mention files copied locally on the receiving side DEL Mention deletions on the receiving side FLIST Mention file-list receiving/sending (levels 1-2) MISC Mention miscellaneous information (levels 1-2) MOUNT Mention mounts that were found or skipped NAME Mention 1) updated file/dir names, 2) unchanged names PROGRESS Mention 1) per-file progress or 2) total transfer progress REMOVE Mention files removed on the sending side SKIP Mention files that are skipped due to options used STATS Mention statistics at end of run (levels 1-3) SYMSAFE Mention symlinks that are unsafe ALL Set all --info options (e.g. all4) NONE Silence all --info options (same as all0) HELP Output this help message Options added for each increase in verbose level: 1) COPY,DEL,FLIST,MISC,NAME,STATS,SYMSAFE 2) BACKUP,MISC2,MOUNT,NAME2,REMOVE,SKIP
对于–info=progress2的输出的信息的含义，可参考：
