| ascp4: Transferring from the Command Line with Ascp 4 | 149
--mode={send|recv}
Transfer in the specified direction: send or recv (receive). Requires --host.
-N pattern
Protect ("include") files or directories from exclusion by any -E (exclude) options that follow
it. Files and directories are specified using pattern. Each option-plus-pattern is a rule. Rules are
applied in the order (left to right) in which they're encountered. Thus, -N rules protect files only
from -E rules that follow them. Create patterns using standard globbing wildcards and special
characters such as the following:
• * (asterisk) represents zero or more characters in a string, for example *.tmp matches .tmp
and abcde.tmp.
• ? (question mark) represents any single character, for example t?p matches tmp but not temp.
For details on specifying patterns and rules, including examples, see Using Filters to Include and
Exclude Files on page 126.
Note: Filtering rules can also be specified in aspera.conf. Rules found in aspera.conf are
applied before any -E and -N rules specified on the command line.
--no-open
In test mode, do not actually open or write the contents of destination files.
--no-read
In test mode, do not read the contents of source files.
--no-write
In test mode, do not write the contents of destination files.
-O fasp_port
Use the specified UDP port for FASP transfers. Default: 33001.
--overwrite={always|never|diff|diff+older|older}
Overwrite files at the destination with source files of the same name based on the method. Default:
always. Use with --compare and --resume. method can be the following:
• always – Always overwrite the file.
• never – Never overwrite the file. If the destination contains partial files that are older or the
same as the source files and --resume is enabled, the partial files resume transfer. Partial files
with checksums or sizes that differ from the source files are not overwritten.
• diff – Overwrite the file if it is different from the source, depending on the compare method
(default is size). If the destination is object storage, diff has the same effect as always.
If resume is not enabled, partial files are overwritten if they are different from the source,
otherwise they are skipped. If resume is enabled, only partial files with different sizes or
checksums from the source are overwritten; otherwise, files resume.
• diff+older – Overwrite the file if it is older and different from the source, depending on the
compare method (default is size). If resume is not enabled, partial files are overwritten if
they are older and different from the source, otherwise they are skipped. If resume is enabled,
only partial files that are different and older than the source are overwritten, otherwise they are
resumed.
• older – Overwrite the file if its timestamp is older than the source timestamp.
-P ssh-port
Use the specified TCP port to initiate the FASP session. (Default: 22)
-p
Preserve file timestamps for access and modification time. Equivalent to setting --preserve-
modification-time, --preserve-access-time, and --preserve-creation-
