ascp: Transferring from the command line
Ascp is a scriptable FASP transfer binary that enables the transfer
to and from Aspera transfer servers to which you have authentication credentials. Transfer settings
are customizable and can include file manipulation on the source or destination, filtering of the
source content, and client-side encryption-at-rest.
Ascp command reference ascp executable is a command line FASP transfer program. This reference describes ascp syntax, command options, and supported environment variables.Ascp general examples Ascp file manipulation examples Ascp can manipulate files and directories as part of the transfer, such as upload only the files in the specified source directory but not the directory itself, create a destination directory, and move or delete source files after they are transferred.Ascp transfers with object storage and HDFS Ascp transfers to and from servers in the cloud are similar to other Ascp transfers, though they might require explicit authorization to the storage as an authorization token or storage credentials.Multi-Session transfers Ascp can transfer content faster by using multi-session transfers (also known as parallel transfers and multi-part transfers) to and from multi-node and multi-core servers and clusters, on premises or in the cloud. This topic describes the syntax of a multi-session transfer and provides an example.Using standard I/O as the source or destination Ascp can use standard input (stdin) as the source or standard output (stdout) as the destination for a transfer. The syntax depends on the number of files in your transfer; for single files use stdio:// and for multiple files use stdio-tar:// . The transfer is authenticated by using SSH or a transfer token.Using filters to include and exclude files ascp transfers all source files in the transfer list.Symbolic link handling Creating SSH keys from the command line Reporting checksums Client-Side Encryption-at-Rest (EAR) .aspera-env extension. Anyone downloading these .aspera-env files must have the password to decrypt them, and decryption can occur as the files are downloaded or later once they are physically moved to a computer with no network connection.Comparison of ascp and ascp4 options ascp and ascp4 ; however, some options are available for only one or the behavior of an option is different. The following table lists the options that are available only for Ascp or Ascp4 , and the options that are available with both. If the option behavior is different, the ascp option has ** added to the end and the difference is described following the table.Ascp FAQs
