Redirecting the output
For example,
if we run the below command,
Code:
symcfg list -thin -pool

, results in an output most of the times and if the out is generated i'm able to redirect the output to a file. but sometimes it doesnt result any output and even though the output is being redirected, i can see "No Thin Pools " on the screen.
script below is what i used

Code:
sudo symcfg list | grep -E 'Local|Remote' | awk '{print $1}' | while read line; do line="${line##*()}";

sudo symcfg -sid "$line" list -thin -pool -GB > /tmp/pooltmp/file_"$line".dat

exists=$(grep -c 'No|error' /tmp/pooltmp/file_"$line".dat)
if [[ $exists -gt 0 ]]
 then
 #echo "No Device Pools"
 echo ""$line"" >> /tmp/pooltmp/nodevicepools.dat
 else
 #echo "Device Pools are configured"
 echo ""$line"" >> /tmp/pooltmp/devicepools.dat
 fi

 done >> /tmp/pooltmp/output

 cat /tmp/pooltmp/devicepools.dat | while read line ; do line="${line##*()}";
 output=`awk 'END{print NR}' /tmp/pooltmp/file_"$line".dat`
 if [[ "$output" -le 2 ]]
 then
 echo ""$line"" >> /tmp/pooltmp/nopoolarrays.dat
 else
 echo ""$line"" >> /tmp/pooltmp/symmetrixid.dat
 fi
 done

 if [[ -f /tmp/pooltmp/symmetrixid.dat ]]
 then
 echo "Refer /tmp/pooltmp/symmetrixid.dat for the Local and Remote VMAX arrays with thin pools"
 else
        echo "No output file generated"
 fi

 if [[ -f /tmp/pooltmp/nopoolarrays.dat ]]
 then
 echo "Refer /tmp/pooltmp/nopoolarrays.dat for the Local and Remote VMAX arrays with no thin pools"
 else
        echo "No Output file generated"
 fi

platform::shell

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
