Validate Service Name Redirection File Format Using Basic Command

The snrfck basic command requires only the -i option to read the redirection file, validate each line, and flag the first incorrect line it encounters.

For example, suppose you enter:

snrfck -ic:\cfg\testfile

where:

cfg is the directory containing the service name redirection file.
testfile is the service name redirection file.

Note: The path cfg\testfile is shown as a PC-based system in the examples.

Next, assume the redirection file contains duplicate entries.

Example of a Redirection File with a Duplicate Entry
requested_service	user_id	application_ name	assigned_service
AS400	Bob	isql	as1
AS400	*	isql	as2
AS400	Bob	isql	as2
AS400	*	Omni	omniA
AS400	*	Power Builder	powerB
DB2	*	Omni	db2omni
DB2	*	*	db2gen
<tab>	*	*	as2

In this example, snrfck returns:

c:\cfg\testfile: line3: duplicate/ambiguous row

If the file does not contain errors, the rows are sorted in the order used in the redirection operation and printed to the current window. The snrfck utility adds line numbers for clarity.

Example of a Correctly Formatted Redirection File
	requested_service	user_id	application_name	assigned_service
1:	<tab>	root	ksh	svc_ksh
2:	db2	joe	isql	svc_db2a
3:	db2	jane	isql	svc_db2b
4:	db2	sonia	Omni	svc_db2c
5:	db2	ramon	Omni	svc_db2d
6:	db2	sven	*	svc_db2gen
7:	other	*	*	svc_other
