Linux命令之rsync基本用法詳解
更新時間：2025年08月04日 09:57:31 作者：小黑要上天
rsync是Linux用于文件/文件夾同步的工具,支持本地及遠程傳輸,常用參數(shù)包含-a（歸檔模式）、-v（詳細輸出）、-z（數(shù)據(jù)壓縮）,可執(zhí)行全量/增量同步、排除文件及刪除目標目錄多余文件等操作,本文介紹Linux命令之rsync基本用法,感興趣的朋友一起看看吧
1.rsync介紹
linux命令rysnc是一個在linux系統(tǒng)上通過網(wǎng)絡在系統(tǒng)間同步文件夾和文件的網(wǎng)絡協(xié)議。
前提：rsync需在遠程和本地系統(tǒng)上安裝
2.rsync用法
rsync [參數(shù)] <source path> <destination path>
| 參數(shù) | 說明 |
| -v | 詳細模式輸出，傳輸時的進度等信息 |
| -z | 傳輸時進行壓縮以提高傳輸效率 |
| -a | 歸檔模式，表示以遞歸方式傳輸文件，并保持所有文件屬性，等于-rtopgdl |
| -l | 會把軟鏈接指向的目標文件復制到對端目錄中 |
| -e | 指定使用ssh還是其他方式來數(shù)據(jù)同步 |
| --bwlimit=10 | 限制傳輸速度 |
| --exclude=PATH | 表示指定排除不需要傳輸?shù)奈募忍柡竺娓募?，可以是萬用字符模式(如：*.txt) |
| --delete | 表示刪除DST中RSC沒有的文件 |
3.實例

socketpairs, hardlinks, symlinks, IPv6, batchfiles, inplace,
append, ACLs, xattrs, iconv, symtimes, prealloc

General Public Licence for details.
rsync is a file transfer program capable of efficient remote update
via a fast differencing algorithm.
Usage: rsync [OPTION]... SRC [SRC]... DEST
or rsync [OPTION]... SRC [SRC]... [USER@]HOST:DEST
or rsync [OPTION]... SRC [SRC]... [USER@]HOST::DEST
or rsync [OPTION]... SRC [SRC]... rsync://[USER@]HOST[:PORT]/DEST
or rsync [OPTION]... [USER@]HOST:SRC [DEST]
or rsync [OPTION]... [USER@]HOST::SRC [DEST]
or rsync [OPTION]... rsync://[USER@]HOST[:PORT]/SRC [DEST]
The ':' usages connect via remote shell, while '::' & 'rsync://' usages connect
to an rsync daemon, and require SRC or DEST to start with a module name.
