The default delimiter is \s+, any amount of any whitespace.

This is the shortest for now. I am not good at awk than perl

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.

perl -ne 'print if (split)[2]==111'
awk does beat shortest possible perl here though.

Gack! That's no better than the grep version!
awk -F'\t' '($3 == 111)' < 1.txt

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

Very quick solution using awk. I know there are other (more pretty) ways, but
this may get you started.
cat | awk '$0 ~ /^.*\t.*\t111.*/'
The regular expression matches:
"111"
So it looks for 111 in 3rd column separated by tabs (I included your column
with a, b, c in a little test so I had

Hi all,
I want to extract the lines of which the specified column is matched
by command line programs(grep,cut,wc,...) not any script file.
For example, there is tab separated matrix text like the following.
and I want to extract of which the value of column number 2 is "111".
