How do i check if all parameters are set in bash?
Hi,

I have 4 parameters passed to my shell and i validate if all four are entered using the following snippet:
Code:
if [ $# -ne 4 ]
then echo "Not entered" 
else echo "entered"
fi

I get the following output as 'Not entered even when i enter the values for all prompts.
Please advise.

Thanks.

pam_radius

PAM_RADIUS(8)						    BSD System Manager's Manual 					     PAM_RADIUS(8)

NAME

     pam_radius -- RADIUS PAM module

SYNOPSIS

     [service-name] module-type control-flag pam_radius [options]

DESCRIPTION

     The RADIUS service module for PAM provides authentication services based upon the RADIUS (Remote Authentication Dial In User Service) proto-
     col.

     The pam_radius module accepts these optional parameters:

     use_first_pass
		 causes pam_radius to use a previously entered password instead of prompting for a new one.  If no password has been entered then
		 authentication fails.

     try_first_pass
		 causes pam_radius to use a previously entered password, if one is available.  If no password has been entered, pam_radius prompts
		 for one as usual.

     echo_pass	 causes echoing to be left on if pam_radius prompts for a password.

     conf=pathname
		 specifies a non-standard location for the RADIUS client configuration file (normally located in /etc/radius.conf).

     nas_id=identifier
		 specifies a NAS identifier to send instead of the hostname.

     template_user=username
		 specifies a user whose passwd(5) entry will be used as a template to create the session environment if the supplied username does
		 not exist in the local password database.  The user will be authenticated with the supplied username and password, but his cre-
		 dentials to the system will be presented as the ones for username, i.e., his login class, home directory, resource limits, etc.
		 will be set to ones defined for username.

		 If this option is omitted, and there is no username in the system databases equal to the supplied one (as determined by call to
		 getpwnam(3)), the authentication will fail.

     nas_ipaddr[=address]
		 specifies a NAS IP address to be sent.  If option is present, but there is no value provided then IP address corresponding to the
		 current hostname will be used.

FILES

     /etc/radius.conf  The standard RADIUS client configuration file for pam_radius

SEE ALSO

     passwd(5), radius.conf(5), pam(8)

     The pam_radius module first appeared in FreeBSD 3.1.  The pam_radius manual page first appeared in FreeBSD 3.3.
