My apologies if this question is so trivial ... I guess there really is a room for dummies ...
Anyway, just wanting to know if someone can please explain what the dot (.) infront of the command or script does and why it works and does not work in the following?
Code:
server01(oracle)[]/u01/bin/oracle/server01$: db01env
ksh: db01env: cannot execute
server01(oracle)[]/u01/bin/oracle/server01$: . db01env
Set up for db01 database (using: /opt/oracle/9.2.0.7)
oracle:db01> ls -l /u02/bin/oracle/db01env
-rw-r--r-- 1 root other 1621 Jun 26 2005 /u02/bin/oracle/db01env
I did a which db01env and it says it is not found even though /u02/bin/oracle is included in the PATH environment variable. I believe this is because db01env is not executable and the which command only checks for executables, is that a correct assumption/guess?
Am not having issues at the moment but just curious how a single dot could make such a big difference that it can make or break stuff
Any response or explanation is very much appreciated.

capture-schema
capture-schema(1m) Application Server Utility capture-schema(1m)NAME
capture-schema - stores the database metadata (schema) in a file for use in mapping and execution
SYNOPSIS
capture-schema-dburl url-username name- password password-driver a_jdbc_driver [-schemaname name] [-table tablename]* [-out filename]
Stores the database metadata (schema) in a file. You can also use the Sun Java System Studio IDE to capture the database schema. Run cap-
ture-schema as the same database user that owns the tables, so that the -username and -schemaname options are given the same username.
Additionally, you can grant the database user running the capture-schema command the ANALYZE ANY TABLE privilege.
OPTIONS -dburl JDBC URL expected by the driver for accessing a database.
-username user name for authenticating access to a database.
-password password for accessing the selected database.
-driver JDBC driver classname in your CLASSPATH.
-schemaname name of the user schema being captured. If not specified, the default will capture metadata for all tables from all
the schemas accessible to this user. Specifying this parameter is highly recommended. If more than one schema is
accessible to this user, more than one table with the same name may be captured which will cause problems.
-table name of the table; multiple table names can be specified.
-out output target; defaults to stdout. This parameter corresponds to the schema sub-element of the sun-cmp-mapping ele-
ment in the sun-cmp-mapping_1_1.dtd file.
EXAMPLES
Example 1: Using capture-schema
capture-schema -dburl jdbc:oracle:thin:@sadbuttrue:1521:ora817
-schemaname cantiflas -username CANTIFLAS -password enigma -driver
