I'm trying to copy my .profile, .rvm and .ssh folders/files to a new computer and I know how to use the cp and ssh commands but I'm not sure how to use them in order to transfer files from one computer to another. Any help would be great, thanks!
You can do this with the scp command, which uses the ssh protocol to copy files across machines. It extends the syntax of cp to allow references to other systems:
scp username1@hostname1:/path/to/file username2@hostname2:/path/to/other/file
Copy something from this machine to some other machine:
scp /path/to/local/file username@hostname:/path/to/remote/file
Copy something from another machine to this machine:
scp username@hostname:/path/to/remote/file /path/to/local/file
Copy with a port number specified:
scp -P 1234 username@hostname:/path/to/remote/file /path/to/local/file
First zip or gzip the folders:
Use the following command:
zip -r NameYouWantForZipFile.zip foldertozip/
or
tar -pvczf BackUpDirectory.tar.gz /path/to/directory
for gzip compression use SCP:
scp username@yourserver.com:~/serverpath/public_html ~/Desktop
You may also want to look at rsync if you're doing a lot of files.
If you're going to making a lot of changes and want to keep your directories and files in sync, you may want to use a version control system like Subversion or Git. See http://xoa.petdance.com/How_to:_Keep_your_home_directory_in_Subversion
