To clarify, here is the quote from the usage:
-s <share> Share name (or - for all) from which path is offset
(don't include the 'f' mangle)
NOTE: if unmangle option (-m) is not set then the share name
is optional and if not specified then it must instead be
included in mangled form as part of the file/directory names.
So, you can do any of the following assuming your share name is '/'
With mangling
BackupPC_deleteFile.pl -h hostname -n - -d 4 f%2f/fvar/flog/fmaillog
BackupPC_deleteFile.pl -h hostname -n - -s / -d 4 /fvar/flog/fmaillog
BackupPC_deleteFile.pl -h hostname -n - -s %2f -d 4 /fvar/flog/fmaillog
Without mangling:
BackupPC_deleteFile.pl -h hostname -n - -s / -m -d 4 /var/log/maillog
BackupPC_deleteFile.pl -h hostname -n - -s %2f -m -d 4 /var/log/maillog
You could also use '-s -' to include any share and you could remove
the leading slash before (f)var in all but the first example.
