Yuck! Look at all of those spaces in the filename! :-) (Recalling all of the discussion over the past couple of days concerning whitespace in filenames and the problems that it causes.) > When these two expand here: > > tar $tarparameters $backuppath | 7z $zparameters $zfilename > > I end up with all of the terms but the $zfilename still needs quoting > somehow as it contains spaces, how do you fix that or do I have to > escape all of the spaces with back ticks? Do you really need spaces in the filename? (Editorial remark: Unix users always avoid putting whitespace in filenames because they are a pain.) You can quote the filenames like this: tar $tarparameters "$backuppath" | 7z $zparameters "$zfilename" Personally I would remove the spaces. And I would use a date format that will sort nicely. I would think that by date would be good enough. zfilename="backup.$(date +"%F").$backuplevel.tar.7z" or with the time too zfilename="backup.$(date +"%F.%T").$backuplevel.tar.7z" By using "%a %h %H%M %d-%m-%Y" (e.g. Fri Jan 0455 14-01-2011) and putting the day of the week first it means that the collation order will be by day of the week. Personally I wouldn't care for that ordering. Instead I would order it %F (e.g. 2011-01-14) so that it will be arranged by time. Bob
