Thanks for the quick response!

I am using netezza sql query like below, and the table contains some 2k records in it.
I want to read the result record by record and pass it in the next set of sql steps.
Code:
course=select course from table group by 1 order by 1;
N=0
for course in `nzsql -host -d db -Atc "course=select course from table group by 1 order by 1;"` ; do
   
      test[$N]="$course"
      echo "$N = $course"     #to confirm the entry
       
  let "N= $N + 1"
create table table2 as
select * from table where course=$course;
One more query here..Query2
Query3

when i use the above for loop it is reading the string line by line but if i have space or special characters between the string then it is considering as next line.
table contains the data like below.
Code:
Java
Oracle/SQL
ANSI SQL
SQL,DWH,DB
DB&Java

Above piece of code is taking the first line Java but when coming to the next line, it is splitting and taking the first word in $course.

grid-change-pass-phrase

GRID-CHANGE-PASS-(1)						  Globus Commands					      GRID-CHANGE-PASS-(1)

NAME

       grid-change-pass-phrase - Change the passphrase of a private key

SYNOPSIS

       grid-change-pass-phrase [-help] [-usage] [-version] [-versions]

       grid-change-pass-phrase [-file PRIVATE-KEY]

DESCRIPTION

       The grid-change-pass-phrase program changes the passphrase protecting a private key or PKCS12 bundle containing a private key and
       certificate. By default, grid-change-pass-phrase uses the X509_USER_KEY environment variable to locate the private key. If that is not set,
       then it looks for $HOME/.globus/userkey.pem and $HOME/.globus/usercred.p12 in succession. The path to a key can be specified by using the
       -file command-line option.

       The full set of command-line options to grid-change-pass-phrase are:

       -help, -usage
	   Display the command-line options to grid-change-pass-phrase and exit.

       -version, -versions
	   Display the version number of the grid-change-pass-phrase command. The second form includes more details.

       -file PRIVATE-KEY
	   Change the passphrase of the private key named by PRIVATE-KEY instead of the default.

EXAMPLES

       Change the passphrase of the default private key:

	   % grid-change-pass-phrase

	   Enter pass phrase for /home/juser/.globus/userkey.pem:
	   writing RSA key
	   Enter PEM pass phrase:
	   Verifying - Enter PEM pass phrase:

ENVIRONMENT VARIABLES

       The following environment variables affect the execution of grid-change-pass-phrase:

       X509_USER_KEY
	   Path to the default private key file.
