scripts, Perl scripts, Windows batch files, and executable binaries that can invoke a variety of
environment variables. For instructions, see
--exclude-newer-than=mtime, --exclude-older-than=mtime
Exclude files (but not directories) from the transfer, based on when the file was last modified.
Positive mtime values are used to express time, in seconds, since the original system time (usually
1970-01-01 00:00:00). Negative mtime values (prefixed with "-") are used to express the number of
seconds prior to the current time.
-f config_file
Read Aspera configuration settings from config_file rather than aspera.conf(the default).
--file-checksum=hash
Enable checksum reporting for transferred files, where hash is the type of checksum to calculate:
sha1, md5, sha-512, sha-384, sha-256, or none (the default). When the value is none,
the checksum that is configured on the server, if any, is used. For more information about checksum
reporting, see
Important: When checksum reporting is enabled, transfers of very large files (>TB) take a long
time to resume because the entire file must be reread.
--file-crypt={encrypt|decrypt}
Encrypt files (when sending) or decrypt files (when receiving) for client-side encryption-at-rest
(EAR). Encrypted files have the file extension .aspera-env. This option requires the encryption/
decryption passphrase to be set with the environment variable ASPERA_SCP_FILEPASS. If a
client-side encrypted file is downloaded with an incorrect password, the download is successful, but
the file remains encrypted and still has the file extension .aspera-env. For more information,
see Client-Side Encryption-at-Rest (EAR)
--file-list=file
Transfer all source files and directories listed in file. Each source item is specified on a separate line.
UTF-8 file format is supported. Only the files and directories are transferred. Path information is not
preserved at the destination. To read a file list from standard input, use "-" in place of file.
For example, if list.txt contains the following list of sources:
/tmp/code/compute.php
doc_dir
images/iris.png
images/rose.png
and the following command is run:
# ascp --file-list=list.txt --mode=send --user=username --
host=ip_addr .
then the destination, in this case the transfer user's docroot, will contain the following:
compute.php
doc_dir (and its contents)
iris.png
rose.png
Restrictions:
• The command line cannot use the user@host:source syntax. Instead, specify this
information with the options --mode, --host, and --user.
• Paths specified in the file list cannot use the user@host:source syntax.
• Because multiple sources are being transferred, the destination must be a directory.
