ftp -in <<FIN 
 
open $SAP_UP_SERVER
 
user $SAP_UP_USER $SAP_UP_PASSWORD

put $PM00_OUTPUTS_DIRECTORY/$SAP_UP_FILE_CSV /SAP_UP_FILE_CSV
 
quit

  1. Use code tags; check your PMs for a guide.
  2. Change "asc" to "bin" and start reading the manual pages for ftp... or documentation of any kind for any future tool you are going to use.
