tr command is used for translating characters, not for filtering columns from an output. As you said, try this:

Code:
ls -l | awk '{ print $5 }'

Thanks for this prompt reply.. But I know this...

What can we use instead of 'awk' to do the same?? cut???

The obvious (and most sensible) command to use is awk.

You can use cut, but first you would have to pipe it through tr to remove multiple spaces:

Code:
ls -l | tr -s ' ' | cut -d ' ' -f 5

Thanks All,

I have got the solution..

Code:
lines=`ls -l | tr -s [:space:] | cut -d ' ' -f 5 | wc -l`
lines=`expr $lines - 1`

echo "Fifth column of 'ls -l' command:::"
ls -l | tr -s [:space:] |cut -d ' ' -f 5 | tail -n $lines
