Tried the below code but it couldn't worked fro me.
Code:
IFS=''
while read course
do
echo $course
done < <(course=`nzsql -host -d db -Atc "select course from table group by 1 order by 1;"`)

For now, i have created a a file from query result and reading from the file.

And i have 2k course names in the table/file, so i have to schedule it in batch wise like 100 courses at a time for the execution on my database.I never tried this before and would it be possible for you to suggest a way how to schedule this requirement as batch jobs

MACHINE-INFO(5) 						   machine-info 						   MACHINE-INFO(5)

NAME
machine-info - Local machine information file SYNOPSIS
/etc/machine-info DESCRIPTION
The /etc/machine-info file contains machine meta data. The basic file format of machine-info is a newline-separated list of environment-like shell-compatible variable assignments. It is possible to source the configuration from shell scripts, however, beyond mere variable assignments no shell features are supported, allowing applications to read the file without implementing a shell compatible execution engine. /etc/machine-info contains meta data about the machine that is set by the user or administrator. Depending on the operating system other configuration files might be checked for machine information as well, however only as fallback. You may use hostnamectl(1) to change the settings of this file from the command line. OPTIONS
The following machine meta data parameters may be set using /etc/machine-info: PRETTY_HOSTNAME= A pretty human-readable UTF-8 machine identifier string. This should contain a name like "Lennart's Laptop" which is useful to present to the user and does not suffer by the syntax limitations of internet domain names. If possible, the internet hostname as configured in /etc/hostname should be kept similar to this one. Example: if this value is "Lennart's Computer" an Internet hostname of "lennarts-computer" might be a good choice. If this parameter is not set, an application should fall back to the Internet host name for presentation purposes. ICON_NAME= An icon identifying this machine according to the XDG Icon Naming Specification[1]. If this parameter is not set, an application should fall back to "computer" or a similar icon name. CHASSIS= The chassis type. Currently, the following chassis types are defined: "desktop", "laptop", "server", "tablet", "handset", as well as the special chassis types "vm" and "container" for virtualized systems that lack an immediate physical chassis. Note that many systems allow detection of the chassis type automatically (based on firmware information or suchlike). This setting (if set) shall take precedence over automatically detected information and is useful to override misdetected configuration or to manually configure the chassis type where automatic detection is not available. EXAMPLE
PRETTY_HOSTNAME="Lennart's Tablet" ICON_NAME=computer-tablet CHASSIS=tablet SEE ALSO
