Hello,

I have created two same directories on two different locations. The structure is as shown below.

/web_upload/
/mnt/web_upload/

Now, I want to merge all contents of both "web_upload" directories into one directory. Simply,i want to copy all data & files from "/web_upload" to "/mnt/web_upload/" , without affecting original data on "/mnt/web_upload/"

Please Help.

yes n | cp -ir web_upload/* /mnt/web_upload

Read man pages of "yes" and "cp"

Dear Friend,

Thanks for prompt reply. As per the "cp" command, I want to ask you simple question.

Will "cp" command overwrite same named directories? Suppose,i have 2 same named directories in 2 different folders. The scenario is given below.

"/data/web_upload/data_27/" directory contains,
file1
file2
file3
SQL Directory

"/mnt/web_upload/data_27/" directory contains,
file1
file2
file4
SQL Directory

So, it is clear that file1,file2 & SQL Directory - common on both directories.

Now, please let me know how to merge all data without overwriting existing files & directories?

Please Help.

It is hard to make cp overwrite entire directories - it will just copy corresponding files into it. Of course there can be name conflicts between files. That's why I recommend studying "-i" option (interactive, implies asking on overwrite) and piping "yes n" (infinite stream of "n") to cp (that way you decline all overwrite requests.

If the remote server don't have "rsync",on which i want to copy data from linux pc,Will "rsync" work?

Simply, i want to merge all data & files on UNIX PC,which don't have"rsync" package. I want to copy all data from linux pc,having "rsync" utility.

is it possible?

What "rsync over ssh" will do?

No, rsync over ssh assumes existence of rsync on both sides.

I want to configure "rsync" on centos 5.2 pc.

after the configuration, "rsync" doesn't show me the "/etc/rsync.conf" file,which is necessary for configuration.

Kindly provide me a good documentation for "rsync"



Thanks in advance.

do you mean /etc/rsyncd.conf ? I am not aware of any requirement for a plain rsync.conf since most of the options are provided on the command-line or from the ssh config files.

unless you want to run this as a daemon process, you don't need rsyncd.conf.

as for documentation, all i can suggest is man and google , or if you need help with something specific, maybe someone here can help.

Dear Friend,

This is my current scenario.

I have 2 same named directories in 2 different folders.
-------------------------------------------------
Server1

"/data/web_upload/data_27/" directory contains,
file1
file2
file3
SQL Directory
-------------------------------------------------
Server2

"/mnt/web_upload/data_27/" directory contains,
file1
file2
file4
SQL Directory
-------------------------------------------------
So, it is clear that file1,file2 & SQL Directory - common on both directories.

Now, please let me know how to merge all data without overwriting existing files & directories?

Thanks,
Nishith Vyas.

Yes.

You are right. I have to install "rsync" on both sides. but, is there any way available to "sync" data without having rsync on remote server?

Kindly Respond.

Nishith.

Please post your thread in only one forum. Posting a single thread in the most relevant forum will make it easier for members to help you and will keep the discussion in one place.

I have merged your two virtually-duplicate threads into one.

Sasha

1. make a backup copy of files on server1

2. use scp to copy dirs/files from eg server 2 to server 1, under a new dir eg server2/mnt/web_upload/data_27/

3. use the concept provided in posts #2, #4 to compare/merge files.

4. if needed, scp new fileset back to server2

5. if this is a problem that arises repeatedly, use the rsync or unison tool to keep the 2 systems synced.

wht type of files are in "/data/web_upload/data_27" directory???and why do you need to merge the 2 directories???
