sftp file compression

Former Member — Tue, 16 Sep 2008 10:51:23 GMT

Hi All,

Im using SFTP batch mode to read a series of commands from an input batchfile instead of stdin.

Example :

sftp -b batchfile user@host

Right now, I need to enable the compression for the file before sending to SFTP server.

I need to add in the switch -C in my Abap program. How to I achieve that?

Add the switch at the back of the code as below?? Please advise.Thanks.

sftp -b batchfile user@host -C

Hi,

I might not be giving u the final solution, but I can help you with compression of the file.

the below code can be made use of, inorder to compress a file.


TYPES:
t_xline(2048) TYPE x, "BINARY FILES

BEGIN OF t_line,
line(1024) TYPE c,
END OF t_line. "CONTENT

DATA:
size type i.

DATA:
data_tab TYPE STANDARD TABLE OF t_xline,
text_tab TYPE STANDARD TABLE OF t_line.

DATA:
input_x type xstring, "BINARY CONTENT INPUT
output_x type xstring. "BINARY OUTPUT OUTPUT

data : CL_ZIP type ref to CL_ABAP_ZIP .


DATA:
name type string.

name = 'c:\error.doc'. "<-- Insert full path of application server

CALL METHOD CL_GUI_FRONTEND_SERVICES=>GUI_UPLOAD
EXPORTING
FILENAME = name
FILETYPE = 'BIN'
IMPORTING
FILELENGTH = size
CHANGING
DATA_TAB = data_tab.


CALL FUNCTION 'SCMS_BINARY_TO_XSTRING'
EXPORTING
INPUT_LENGTH = size
IMPORTING
BUFFER = input_x
TABLES
BINARY_TAB = data_tab.

CREATE OBJECT cl_zip.

cl_zip->ADD(
EXPORTING
NAME = name
CONTENT = input_x
)
.

cl_zip->SAVE(
RECEIVING
ZIP = output_x
)
.

REFRESH data_tab.

CALL FUNCTION 'SCMS_XSTRING_TO_BINARY'
EXPORTING
BUFFER = output_x
IMPORTING
OUTPUT_LENGTH = size
TABLES
BINARY_TAB = data_tab
.
DATA:
lw_output_path TYPE string.

lw_output_path = 'c:\myfile.zip'. " specify the application server path where u want to create zip file.


CALL METHOD CL_GUI_FRONTEND_SERVICES=>GUI_DOWNLOAD
EXPORTING
BIN_FILESIZE = size
FILENAME = lw_output_path
FILETYPE = 'BIN'
CHANGING
DATA_TAB = data_tab
.

Regards,

Kiran

Hi Kiran,

Thanks for your code.

My requirement is to retain the code and just require to add the switch -C in somewhere else to achieve the compression.

Is my current way to append the -C at the back of the batch mode code is correct?
