[olug] Script help

[Kevin]

First thing I see wrong, that correcting will result in a different
error message: There are spaces surrounding your equals sign. Remove
them and it will result in assigning to DIRNAME the following:
"backup_", sans quotes. This assumes that date is an empty variable.
You will also need to tell bash to run the date command by placing
them in parenthesis.

DIRNAME="backup_$(date +%Y-%m%d)" to give "backup_2008-1228", sans quotes.
or
DIRNAME="backup_$(date +%F)" to give "backup_2008-12-28", also sans quotes.
