Here's the script. The problem line is in red (error in first post).

Since I'm a n00b, I welcome any security tips in writing this script as well.

Example usage: ./restore.sh 05-20-12 may20 whereby 05-20-12 is a datestamp of the DB file (i.e. backup.05-20-12.sql) and may20 is the database to-be-created in MySQL (that will hold the restored data).

I've been using TextEdit on my Mac (plaintext format, not rich-text) and copying the script into the file via the nano command. Would that be causing a problem, even if TextEdit is in plain-text editing mode?

Code:

#!/bin/sh

cat <<Header

MYSQL_TZINFO_TO_S(1)					       MySQL Database System					      MYSQL_TZINFO_TO_S(1)

NAME

       mysql_tzinfo_to_sql - load the time zone tables

SYNOPSIS

       mysql_tzinfo_to_sql arguments

DESCRIPTION

       The mysql_tzinfo_to_sql program loads the time zone tables in the mysql database. It is used on systems that have a zoneinfo database (the
       set of files describing time zones). Examples of such systems are Linux, FreeBSD, Solaris, and Mac OS X. One likely location for these
       files is the /usr/share/zoneinfo directory (/usr/share/lib/zoneinfo on Solaris). If your system does not have a zoneinfo database, you can
       use the downloadable package described in Section 10.6, "MySQL Server Time Zone Support".

       mysql_tzinfo_to_sql can be invoked several ways:

	   shell> mysql_tzinfo_to_sql tz_dir
	   shell> mysql_tzinfo_to_sql tz_file tz_name
	   shell> mysql_tzinfo_to_sql --leap tz_file

       For the first invocation syntax, pass the zoneinfo directory path name to mysql_tzinfo_to_sql and send the output into the mysql program.
       For example:

	   shell> mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root mysql

       mysql_tzinfo_to_sql reads your system's time zone files and generates SQL statements from them.	mysql processes those statements to load
       the time zone tables.

       The second syntax causes mysql_tzinfo_to_sql to load a single time zone file tz_file that corresponds to a time zone name tz_name:

	   shell> mysql_tzinfo_to_sql tz_file tz_name | mysql -u root mysql

       If your time zone needs to account for leap seconds, invoke mysql_tzinfo_to_sql using the third syntax, which initializes the leap second
       information.  tz_file is the name of your time zone file:

	   shell> mysql_tzinfo_to_sql --leap tz_file | mysql -u root mysql

       After running mysql_tzinfo_to_sql, it is best to restart the server so that it does not continue to use any previously cached time zone
       data.
