UNZIP file from ABAP

Question

Hi,
I have a requirement to retrieve a zip file from the FTP Server, unzip it to the SAP Server and process the unzipped files. Retrieving the data from the FTP server should work via FTP commands which can be executed from within an ABAP program. However, the problem is unzipping these files via ABAP and put them on the server as well. 1. How to do this from within an ABAP Program? (unix commands?)
2. Can I unzip these files with or without using the folder structure? (additional parameter for unix command?)
Kind regards,
Micky.

Answer 1

REPORT ZTESTUNIX line-size 400
                no standard page heading.
selection-screen begin of block ucmd with frame title text-001.
parameters: unixcom like   rlgrap-filename.   " ...SAP Interface file
selection-screen end of block ucmd.
data: begin of tabl occurs 500,
        line(400),
      end of tabl.
data: lines type i.
start-of-selection.
  refresh tabl.
  call 'SYSTEM' id 'COMMAND' field unixcom
                id 'TAB'     field tabl[].
  describe table tabl lines lines.
  loop at tabl.
    write:/01 tabl-line.
  endloop.
  skip 2.
  if lines = 0.
    write:/ 'NO Occurances were found'.
  else.
    write:/ 'Command was successfully executed' color col_total.
    write:/ 'Number of entries in Search' color col_total,
             lines color 6.
  endif.
end-of-selection.
while running give the command as
<b>unzip test.zip  -x dir</b>
then it will unzip test.zip file to dir called dir.
you can specify the filepath instead of file...
