Copy and synchronize file commands between Linux machines

2. 1 different machine copy files
4. SCP file Login user @ Machine ip:/Directory/Sub-directory
6. SCP filename [email protected]10.20. 130.202:/home/test/
10. 2 file [clip] Sync rsync
12. Question [NET friend proposed]
14. How do I write a command of a Linux value that copies one or several subdirectories? If there are several directories under/project,/project/aaa/project/ccc/project/ddd .... I want to copy the PROJECT/AAA into the/tmp directory, the project directory is also copied (and you don't want to use mkdir to create project in the TMP directory first.) Because this is just an example), I actually want to back up the system, that is, some folders and files in a directory to backup, but some folders and files are not copied, such as log folders, etc.
18. Look at the following directory
20. [[email protected] dass] # ll
22. Total 260
24. Drwxrwxr-x 7 dass dass 4096 Oct bonus-portal
26. Drwxrwxr-x 8 dass dass 4096 Mar cis-portal
28. DRWXRWXRWX 6 201 201 4096 Nov cronolog-1.6. 2
30. -rw-rw-r-- 1 dass dass 193967 Oct cronolog-1.6. 2.tgz
32. Drwxr-xr-x 8 dass dass 4096 Oct iad-api
34. Drwxr-xr-x 8 dass dass 4096 Oct ias-api
36. Drwxr-xr-x 8 dass dass 4096 Oct ias-iboss
38. Drwxrwxr-x 7 dass dass 4096 Oct info-portal
40. Drwxrwxr-x 7 dass dass 4096 Oct pis-portal
42. Drwxrwxr-x 7 dass dass 4096 Apr 4 pp_tomcat6
44. Drwxr-xr-x 7 dass dass 4096 Nov regist-api
46. Drwxrwxr-x 7 dass dass 4096 Oct sis-portal
48. Drwxrwxr-x 7 dass dass 4096 3 :sqxx-portal
50. Drwxr-xr-x dass dass 4096 Oct ( tomcat )
52. Drwxrwxr-x 7 dass dass 4096 Oct tvs-portal
54. Drwxr-xr-x 7 dass dass 4096 Nov vod-img-task
56. Drwxr-xr-x 7 dass dass 4096 Oct vod-portal
58. [[email protected] dass] # pwd
60. /opt/dass
64. Just want to copy the/opt/dass/tomcat directory to/tmp
66. Execute the following command:
68. Rsync-ar/opt/dass/tomcat/tmp
72. What is Rsync?
74. SHANGHAI-big wave scouring sand () :
76. Synchronization commands
78. And you can sync it to another machine.
80. Pingxiang-Mark Hurd () :
82. Oh
84. SHANGHAI-big wave scouring sand () :
86. The same file will not be copied again
88. Pingxiang-Mark Hurd () :
90. As if it was a RAC or something.
92. SHANGHAI-Big Wave Amoy () :
94. Why I only add-R No,-ar on the line-a see man is archive
96. Man can't understand, ah, can use on the line!
98. Shanghai-miracle (): :
100. It is a quick means of saying you want recursion and want to preserve almost everything-a this should be allowed to be recursive and reserved permissions
104. SHANGHAI-Big wave Amoy :
106. Well
108. Shanghai-miracle () :
110. If you have a hard link, add-h
