A new version a14.sh.txt is created which supports a format of saved passwords. The bash shell and Perl scripts are zipped and available on the web [zip], and also are embedded below (for an MS Word version of this document [doc]):

The new version of the script deals with a well structured password file, having the following format (where the asterisks are to be replaced by password values):

ftp switzernet.com switzern ******

ftp www.unappel.ch unappel ******

ftp unappel.ch unappel ******

ftp intarnet.com intarnet ******

ftp parinternet.ch parinter ******

The differences between the old and new scripts show that a function ftp_upload is added, responsible for uploading the results to 5 different mirror FTP servers:

The new version (a14.sh.txt) is currently executed twice per day by the cron:
