NS
LW
EA

awk '{up=toupper($2);a[up]}END{for(i in a) print i}' infile
This gives me the desired output..

Code:
awk '{up=toupper($2);a[up]}END{for(i in a) print i}' infile

But you can try also jim mcnamara suggestion which is better and shorter...

Code:
awk '!arr[$2]++ {print $2}' inputfile

Hi malcomex
Thank you. This command is working for me Smilie

Code:
awk '{up=toupper($2);a[up]}END{for(i in a) print i}' infile
 
NS
LW
EA

can you also tell me a function to read these values one by one ? I mean the output should be,

Code:
proceed with NS [Y/N] ?

and it should take the input from user Y or N

if it is Y it will call a function , if it is N again should display next value from the column like

Code:
proceed with LW [Y/N]?

can you please help me?Im really worried to get it Smilie

I think you have blank lines in your file but this should solve it...

Code:
#!/bin/ksh
awk 'NF{up=toupper($2);a[up]}END{for(i in a) print i}' infile | while read line
do
echo "Proceed with ${line}: Y/N:"
read ans < /dev/tty
if [[ ${ans} = "Y" ]]; then
  echo ${line}
fi

done
