pg_backup.sh: "No such file or directory" for pg_backup.config

In order to create backups of a postgres DB, I downloaded the backup scripts provided here.

I created a pg_backup.config which is located in /etc. Put pg_backup.sh in /usr/local/bin. When trying to run the script, like so:

$ pg_backup.sh -c /etc/pg_backup.config

... I get the following error message:

/usr/local/bin/pg_backup.sh: line 27: /usr/local/bin/pg_backup.config: No such file or directory

Is there something I'm doing wrong? Obviously, the script tries to load the configuration from /usr/local/bin/pg_backup.config, although I specified /etc/pg_backup.config as config input. How can I specify from where to load the configuration?

That script seems to accept a config file on the command line but then also requires one to exist next-to the binary itself (and finds that location in a less than robust way1).

The script is just broken.

The very first thing it does is parse its command line options (using a manual while loop). As it does so it removes them from the positional parameters (using shift). It stops that loop when there are no more positional parameters (when [ $# -gt 0 ] is no longer true).

Immediately upon draining the positional parameters it then goes and checks the count of positional parameters again (if [ $# = 0 ]; then) and when, inevitably, it finds that there are no more positional parameters it attempts to source its default configuration file.

The pg_backup_rotated.sh script, in contrast, has a much more reasonable mechanism for loading a configuration file (though it still uses the less-than robust way of finding the location for the default config file).
