Little script for simple db2 database backup with progress bar.
Hello again from somewhere,
since a few months ago I have had to interact a lot with db2 for laboral reasons. Personally after "touch" db2 I think it's quite "pretty" the interaction with it. But a partner complains that she can't know the amount of progress without use the command db2 list utilities show detail, and their use may be uncomfortable for non-shell user.
After this little history i wrote an ugly bash script for this purpose (make simple backups and see the amount of progress with the plus of a progress bar :p)

Eviux thanks for your complaints to the shell xD
