Hi All. Thanks for your valuable suggestions.

With the help of my colleagues, I'm able to do what I was expecting to do. Here is the code which works for me.

Code:
for userid in `awk 'NR==1, NR==25' user-ids.txt`;
do
aws workspaces command to create workspaces  UserName=$userid,BundleId=<bundleID>
done
for userid in `awk 'NR==26, NR==50' user-ids.txt`;
do
aws workspaces command to create workspaces  UserName=$userid,BundleId=<bundleID>
done

DtWsmGetWorkspacesOccupied(library call)								  DtWsmGetWorkspacesOccupied(library call)

NAME

       DtWsmGetWorkspacesOccupied -- get the workspaces in which a window resides

SYNOPSIS

       #include <Dt/Wsm.h>
       Status DtWsmGetWorkspacesOccupied(
       Display *display,
       Window window,
       Atom **ppaWorkspaces,
       int *pNumWs);

DESCRIPTION

       The  DtWsmGetWorkspacesOccupied	function  works  with the CDE workspace manager, dtwm(1), and returns the list of workspaces in which this
       window resides.	Each element of the list is the name of a workspace (converted to an X atom).

       The display argument is the X display.

       The window argument is the window of interest.

       The *ppaWorkspaces argument is the address of a pointer to receive the pointer to a list of workspace names (converted to X atoms).

       The pNumWs argument is the address of an integer to receive the number of elements in the list of workspaces returned in *ppaWorkspaces.

RETURN VALUE

       Upon successful completion, the DtWsmGetWorkspacesOccupied function returns Success and the workspace manager returns in  *ppaWorkspaces  a
       list  of  atoms identifying the occupied workspaces, and returns in pNumWs the number of occupied workspaces; otherwise, it returns a value
       not equal to Success.

APPLICATION USAGE

       If the DtWsmGetWorkspacesOccupied function is not successful, failure may be due to a memory allocation error or failure to find  the  cor-
       rect  workspace information (that is, the CDE workspace manager, dtwm(1), is not running).  The application must use XtFree(3) to free data
       returned in *ppaWorkspaces.

SEE ALSO

       Dt/Wsm.h - DtWsm(5), XtFree(3), dtwm(1).
