Automating executing commands on multiple tapes and changing (loading) them

The thing that we need to be able to do is:

- Scanning tapes from failed backup jobs with bscan (a bacula command)
- loading the next tape with the mtx command

Bscan does unload tapes but does not load them.

Bscan comes with this message when it's done with a tape:

Mount Volume "XO7563L3" on device "Tape1" (/dev/nst0) and press return when ready:

The script doesn't have to be fancy like determine in what slot the volume is. It would be enough just loading the tapes from let's say slot 10 to 24 and we need to make sure they are loaded in the right order into the tape library.

The thing that we ran into is that when the above message appears it normally should input the answer but in this case it should run another command first and then input the answer.

Is Expect the program for the job and how to do it?

Thanks...

AMREPORT(1)						      General Commands Manual						       AMREPORT(1)

NAME
amreport - generate a formatted output of statistics for an Amanda run SYNOPSIS
amreport [ config ] [ -l logfile ] [ -f outputfile ] [ -p postscriptfile ] DESCRIPTION
Amreport generates a summary report of an amanda(8) backup run. If no configuration name is specified, amanda.conf is read from the cur- rent directory. See the amanda(8) man page for more details about Amanda. OPTIONS
config Name of the configuration to process. [-l logfile] Name of the log file to parse to generate the report. If a log file is not specified, it defaults to the file: logdir/log where logdir is the log directory defined in amanda.conf. [-f outputfile] Normally, amreport sends the report via e-mail to the mailto user as defined in the amanda.conf file. If outputfile is specified, then the report is put in outputfile. [-p postscriptfile] Send the postscript output to the file postscriptfile instead of to the lpr(1) command. This option has an effect only if the lbl- templ directive is specified in amanda.conf. LABEL PRINTING
Amanda can print postscript labels describing the contents of tape(s) written in a run. The labels are designed to be folded and inserted into the tape case along with the tape or hole punched and put in a 3-ring binder. Various label templates are provided to format data for different tape sizes. The information printed varies slightly between label templates due to size constraints. Labels contain one line for each host/file-system pair and may also contain the file number on the tape, the level of the dump, the original size of the dump and the size of the (possibly compressed) tape file. Add the lbl-templ parameter to the tapetype definition in amanda.conf to enable labels. If you don't add this line to your tapetype defi- nition, amreport will not print tape labels. You may use the printer keyword in amanda.conf to print to other than the system default printer. TEMPLATES
Amanda provides label templates for the following tape types. These are pretty generic labels and should be easy to customize for other tape types or particular site needs. * ExaByte 8mm tapes * DAT 4mm tapes * DLT tapes * 3-ring binder The 3-ring binder type is the most generic. It may be used to make a hardcopy log of the tapes. SEE ALSO
