But you're not specifying the command-line option that tells the script 
you're specifying a filename.

 - What you're doing:

./mythconverg_restore.pl file.sql.gz

(which will never work) or

./mythconverg_restore.pl /path/to/file.sql.gz

 - What you could do:

./mythconverg_restore.pl --filename /path/to/file.sql.gz

(assuming you do not have a backuprc file that specifies a 
directory--otherwise, you'd have to specify a blank directory with 

 - The *right* way to do it:

./mythconverg_restore.pl --directory /path/to --filename file.sql.gz

(It's designed such that you specify a directory and/or a filename, but 
if you don't supply a directory, you can use an absolute path to the 
file, as in the "What you /could/ do".)


For future reference, if you tell people what command you ran, they can 
help you figure out what you did wrong (even if they don't know the 
script inside-out)...  The possibility exists--though I'm sure it's a 
tiny possibility--that the problem lies not with the backup or with the 
restore script...

Also, there /is/ a mythconverg_restore.pl --help so you can help 
yourself.  Though it has a lot of info, the quick start is generally 
enough.  I'll change it to do the quick start info for --help and have 
an extended help with everything.

I'll also put an error message in there that tells people to fix their 
command line when they specify an invalid database information file.
