Thank you.
You mean -w option?
I want to uniq by any column,any data. For example,
if 2nd column uniq is operated,
1 a
BBB 100 bbb
CC 100 cc
the output will be
10000 a
BBB 100
a 91
2 dog 62
3 apple 89
-
the output will be
-
1 eagle 197
2 camera 91
3 apple 89
-
Such a editing is easy in perl script but I cannot easily do that
in command line.
Is there any idea?

This is the shortest for now. I am not good at awk than perl
but I'll usually use this.

The default character of delimiter seems to be space, so
this does not work well.
Instead, I write
perl -ne 'print if (split(/\t/))[2]==111'
Then, it worked well.

Oh, you are one liner.
This sentence is a little long but I am used to perl so
it is relatively easy.

is confused and very very slow and not smart.
I wonder if I could use "grep" together "cut" command.
Is there any idea?
