Thanks for the suggestion...I have executed only $A as per your suggestion..its working fine from command but displaying NO/BLANK Output.

[core4.1_txn5@stack1-srv1 SCRIPTS]$ cat aa
A=`top -d 1 -n 1 | awk '/^CPU states/ {print $3,$5,$7,$9} /^Mem/ {print $2,$3,$4,$5,$6,$7,$8,$9,$10}'`
echo $A
[core4.1_txn5@stack1-srv1 SCRIPTS]$
[core4.1_txn5@stack1-srv1 SCRIPTS]$ ./aa >> opt
[core4.1_txn5@stack1-srv1 SCRIPTS]$
[core4.1_txn5@stack1-srv1 SCRIPTS]$ cat opt
8309804k total, 2025836k used, 6283968k free, 100812k buffers
[core4.1_txn5@stack1-srv1 SCRIPTS]$
[core4.1_txn5@stack1-srv1 SCRIPTS]$ crontab -l
* * * * * ./SCRIPTS/aa >> /home/core4.1_txn5/SCRIPTS/opt
[core4.1_txn5@stack1-srv1 SCRIPTS]$
[core4.1_txn5@stack1-srv1 SCRIPTS]$ cat opt
8309804k total, 2025836k used, 6283968k free, 100812k buffers





[core4.1_txn5@stack1-srv1 SCRIPTS]$
[core4.1_txn5@stack1-srv1 SCRIPTS]$

As you can see, its showing blank output in the OPT file.

As i m reading many forums..i think the problem is that, in my case, the AWK command is not working through Crontab. I am not sure but i think this is due to some ENVIREMENT ISSUE...something I have to declare in the script so that it can read..

Please correct me if m wrong..

set_color

set_color(1)                                                           fish                                                           set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
