Hi RudiC , I just tried it now. If I run the command as zabbix user by escaping double quotes it ran correctly.
Code:
su -l zabbix -s /bin/bash -c "nodetool cfstats cassdb.tests | grep \"Memtable switch count\""
Memtable data size: 12

But problem is this is not working from bash script. Below is the script I am trying.
Code:
#!/bin/bash
KEYSPACE="$1"
ATTRIBUTE="$2"
nodetool cfstats cassdb.${KEYSPACE} | /bin/grep "$ATTRIBUTE" | awk -F: '{print $2}' | sed -e 's/^[ \t]*//'

When I run above script as root user it works perfectly.
Code:
#/opt/zabbix/cassandra.sh tests "Memtable switch count"
12

Where as when executed as zabbix user it dosent works.
Code:
su -l zabbix -s /bin/bash -c "/opt/zabbix/cassandra.sh tests "Memtable switch count""
109
0
105
12

Here 12 is printed as bottom along-with other attributes values which has "Memtable" string in it.

I tried escaping double quotes from bash script but somehow not able to figure out exact syntax.

Thanks RavinderSingh, I tried both the options which you provided but they are not working. No output for the command.

Thanks,
Pushpraj

gst-complete-0.8

gst-complete-0.8(1)						   User Commands					       gst-complete-0.8(1)

NAME

       gst-complete-0.8, gst-complete - perform bash completion for gst-launch command lines

SYNOPSIS

       complete -Cgst-complete-0.8 gst-launch

       gst-complete [--gst-list-mm] [--gst-mm=string] [--print]

DESCRIPTION

       gst-complete-0.8 enables bash to provide context-sensitive tab completion for gst-launch command lines. See gst-launch(1) for the syntax of
       gst-launch command lines.

       You must have a version of bash that supports programmable completion. Such versions of bash provide the complete built-in command.

       gst-complete is a wrapper script that runs the latest installed version of gst-complete-X.X. For example, if both gst-complete-0.7 and gst-
       complete-0.8 are installed on your system, gst-complete runs gst-complete-0.8.

OPTIONS

       The following options are supported by gst-complete-0.8 and gst-complete:

       --help	       Display detailed usage message. You can also use -? to specify this option.

       The following options are supported by gst-complete only:

       --gst-list-mm   List found major/minor versions. This option displays the versions that are available.

       --gst-mm=string Force  major/minor  version.  This  option  enables you to specify a specific version to run, if you do not want to run the
		       default version.

       --print	       Print wrapped command line. This option displays the command that will be run, and then runs the command.

EXAMPLES

       Example 1: Generating the Registry of Available Plugins by Running gst-compprep

       Run the following command in your .bash_profile or other appropriate place:

       example% complete -C gst-complete-0.8 gst-launch

       Example 2: Running the Wrapper Script and Displaying the Command Name

       example% gst-complete --print
       /usr/bin/gst-complete-0.8

FILES

       The following files are used by this application:

       /usr/bin/gst-complete-0.Executable for bash completion for gst-launch

       /usr/bin/gst-complete   Wrapper script that runs the latest installed version of gst-complete-X.X
