Linux server and ksh shell script.

Don't know C or C++.
Code:
#!/bin/ksh
DATAFILE=/path/to/file/containing/user+password # both on one line separated by a <space>.
JOBLOG="what ever this is"
SQLLDR_CTL="what ever this is"
INFILE="what ever this is"

#=================================================
# Get private data from data file readable by everyone.
#=================================================

read -r loginName password < "$DATAFILE"

#=================================================
# Run SQL Loader
#=================================================

sqlplus -S "$loginName@UAT/$password" <<EOF
  
sqlldr "$loginName@UAT/$password" log="$JOBLOG" control="$SQLLDR_CTL" data="$INFILE" errors=10000 direct=true rows=10000

EOF

My original post had several typos as pointed out by RudiC in a private message. (The read had loginName twice instead of loginName and password and the sqlplus command had unquoted literal strings instead of quoted variable expansions.) I apologize for anyone who read this message before the corrections were made.

gshadow

GSHADOW(5)						   File Formats and Conversions 						GSHADOW(5)

NAME

       gshadow - shadowed group file

DESCRIPTION

       /etc/gshadow contains the shadowed information for group accounts.

       This file must not be readable by regular users if password security is to be maintained.

       Each line of this file contains the following colon-separated fields:

       group name
	   It must be a valid group name, which exist on the system.

       encrypted password
	   Refer to crypt(3) for details on how this string is interpreted.

	   If the password field contains some string that is not a valid result of crypt(3), for instance ! or *, users will not be able to use a
	   unix password to access the group (but group members do not need the password).

	   The password is used when a user who is not a member of the group wants to gain the permissions of this group (see newgrp(1)).

	   This field may be empty, in which case only the group members can gain the group permissions.

	   A password field which starts with an exclamation mark means that the password is locked. The remaining characters on the line
	   represent the password field before the password was locked.

	   This password supersedes any password specified in /etc/group.

       administrators
	   It must be a comma-separated list of user names.

	   Administrators can change the password or the members of the group.

	   Administrators also have the same permissions as the members (see below).

       members
	   It must be a comma-separated list of user names.

	   Members can access the group without being prompted for a password.

	   You should use the same list of users as in /etc/group.

FILES

       /etc/group
	   Group account information.

       /etc/gshadow
	   Secure group account information.
