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".
------------------------
a 1957 111
b 1902 222
c 2001 111
------------------------
i.e. the output will be
----------------
a 1957 111
c 2001 111
----------------
Such a editing is easy in perl script but I cannot easily do that
in command line.
grep -P "^.+?\t.+?\t111\n" 1.txt
is confused and very very slow and not smart.
I wonder if I could use "grep" together "cut" command.
Is there any idea?
