Assuming os x on the local machine and Ubuntu Linux remote.
First I will create tar archive with tar
tar -cvzf lessons.tar.gz lessons
Flags: c - create v - verbose z - gzip f - archive filename
Then split files in smaller pieces if something goes wrong with a connection.
split -b 250mb lessons.tar.gz lessons_part_
This will create files
lessons_part_aa
lessons_part_ab
lessons_part_ac
lessons_part_ad
...
When you want to send files from local computer to remote you can use scp tool
scp ./lessons_part_a* root@remote-host.net:/root/tmp/
After broken connection you can continue with command
scp ./lessons_part_a{g,h,i} root@remote-host.net:/root/tmp/
I probably shouldn't use root user.
I wanted to check if files are ok. Type md5 * to get md5 hashes on my mac, and md5sum * on the remote Ubuntu. If the has numbers are same then everything is good.
Now ssh to the remote.
ssh root@remote-host.net
cd /root/tmp/
and join the files
cat lessons_part_a* > lessons.tar.gz
and extract tar archive
tar -xzvf lessons.tar.gz
There are smarter and easier ways to accomplish same thing, but this was fun and educational. I learned few new commands.
