mosh

basic things

mosh opc@oracle-learn             # 1) learn.ilima.xyz
mosh opc@oracle-docker            # 2) docker.ilima.xyz

# upload: local -> remote
scp ~/Downloads/file.txt opc@oracle-learn:/home/opc/file.txt
# download: remote -> local
scp opc@oracle-learn:/home/opc/file.txt ~/Downloads/

when an IDE instance die/stop/shutdown

# start Docker
sudo systemctl start docker

# stop Docker
sudo systemctl stop docker
sudo systemctl stop docker.socket

# give it a go
sudo docker run hello-world

Synchronize a local directory with a remote machine utilizing Secure Shell (SSH) protocol. 

# synchronize folder to a remote machine using ssh

# sync the remote destionation to a local destination
rsync -urltv -e ssh opc@oracle-learn:/home/opc/tmp-20240309-2236/ `realpath ~/Downloads/tmp`

# from local destination to a remote destination
rsync -urltv -e ssh `realpath ~/Downloads/tmp` opc@oracle-learn:/home/opc/tmp-20240309-2236/

Note: the rsync options used here are:

  • -u, --update skip files that are newer on the receiver
  • -r, --recursive recurse into directories
  • -l, --links copy symlinks as symlinks
  • -t, --times preserve modification times
  • -v, --verbose increase verbosity
  • --delete delete extraneous files from dest dirs, acts as --delete-during
  • -a option means “archive mode” which can be used to sync directories, transfer files, and preserve ownership and permissions.
  • lastly, -e is the option that allows you to specify your remote shell, in this case ssh
