  • Locally watch MySQL process list update every 5s on a remote host. While you watch pipe to a file. The file out put is messy though but hey at least you have a history of what you see.

  • It's useful mostly for your custom scripts, which running on specific host and tired on ssh'ing every time when you need one simple command (i use it for update remote apt repository, when new package have to be downloaded from another host). Don't forget to set up authorization by keys, for maximum comfort. Show Sample Output


    -3
    echo -e '#!/bin/bash\nssh remote-user@remote-host $0 "$@"' >> /usr/local/bin/ssh-rpc; chmod +x /usr/local/bin/ssh-rpc; ln -s hostname /usr/local/bin/ssh-rpc; hostname

  • Execute it from the source host, where the source files you wish backup resides. With the minus '-' the tar command deliver the compressed output to the standar output and, trough over the ssh session to the remote host. On the other hand the backup host will be receive the stream and read it from the standar input sending it to the /path/to/backup/backupfile.tar.bz2 Show Sample Output


    13
    tar jcpf - [sourceDirs] |ssh user@host "cat > /path/to/backup/backupfile.tar.bz2"

  • This improves on #9892 by compressing the directory on the remote machine so that the amount of data transferred over the network is much smaller. The command uses ssh(1) to get to a remote host, uses tar(1) to archive and compress a remote directory, prints the result to STDOUT, which is written to a local file. In other words, we are archiving and compressing a remote directory to our local box.

    ssh user@host "tar -zcf - /path/to/dir" > dir.tar.gz
