tar zcf - /data2/: Run tar command to create a compressed archive of the /data2/ directory using the following tar options:.Hence, let me break it down step by step for you: It is a pipeline consisting of multiple Linux commands.

$ tar zcf - /data2/ | gpg -e | ssh 'cat - > .gpg' The remote server saves the encrypted archive file with a dynamically generated filename based on the current date: The following shell kung-fu compresses the /data2/ directory, encrypts it using gpg, and then transfers the encrypted archive to the remote server nas03 using SSH. In this example, archive /data2/ with gpg command. $ ls -l Making an encrypted archive with tar and ssh # tar zcvf - /Sample outputs: tar: Removing leading `/' from member names The following command backups /(IP 192.168.1.201) host over ssh session: >: This final part of the shell kung-fu redirects the output of the command to the file “ ” on the local host in the current directory.The -cf - options tell tar to create the archive and write it to standard output (stdout).The -C option is passed to the tar to change to the directory /etc/nginx/ before creating the archive.

The -I option is passed to the tar to compress the output.

'tar -I 'gzip -9' -C /etc/nginx/ -cf - nf': This is the command that is executed on the remote host named The tar command options are as follows:.

ssh : This command connects to the remote host www-1 as the user ubuntu using the SSH.

Here is a breakdown of the shell kung-fu for you: The above command will create a compressed archive of the file nf in the directory /etc/nginx/ on the remote server named on the local host or desktop. $ ssh 'tar -I 'gzip -9' -C /etc/nginx/ -cf - nf' > $ ssh 'cd /dir1/ & tar -cf - file | gzip -9' > In this following example, I’m going to use the ssh command to connect to the remote host and executes the following command on the remote host to make a new file named on the local machine: $ set -o noclobber Here is another syntax Of course, bash users can use the ‘ noclobber‘ option using the set command to prevent overwriting with the ‘ >‘ operator. WARNING! The ‘ >‘ operator overwrites existing files, so be cautious with filenames and commands that generate a lot of output and can quickly consume disk space.

/dir1/ : The name of the directory that will be archived using the tar command on that server ( /destination/ : It is the file that will be created on the local host.

But, in this case, you state that the archive should be written to the standard output instead of a file.

Typically you pass the archive name to the -f option. - : The hyphen (“ -“) denotes the standard output (stdout).czf : Make a compressed archive in the.tar : Creating or extract archives using the tar command.: It is the username and hostname of the remote host.ssh : Connect to remote host using ssh.using SSH, creates a compressed tar archive of the “ /dir1/” directory on that server and saves it as a local compressed archive named /destination/: The above command connects to a remote host named box as user named user (e.g. The syntax is as follows to ssh into box and run the tar command (do not miss the > operator): Let us see some examples of how to use the tar command over ssh securely to create archives on Linux, BSD/macOS or Unix-like system. You can use Unix/Linux pipes to create archives. Do not use telnet/nc command due to insecure conection. The GNU version of the tar archiving utility (and other old versions of tar) can be used through the network over ssh session. How do I use tar command over secure ssh session running on Linux or Unix-like system? How do I extract tar archive via SSH based network connection?

Ssh copy files to remote server
