1. The problem statement, all variables and given/known data:
You are given a ANSI text file (a.txt) in the following format and with the following contents-:

Code:

NAME ROLL MARKS 
Sam  05      80 
John 06      90 
Mark 07      90

Columns are separated with just one space. That means that there is only one space separating name from roll and one space separating roll from marks. There may be multiple spacing in the data as seen in the last column of marks.

The objective is to print the header information and then the details of JOHN only.

The output will look like the following-:

Code:

NAME ROLL MARKS 
John 06      90

You cannot use two separate commands by using the ";" format to write both commands. You must use pipes and redirection to combine filter commands to get the desired output.
2. Relevant commands, code, scripts, algorithms:

All filter commands can be used. The resultant command must work on a BASH shell and on any Linux distro.

3. The attempts at a solution (include all code and scripts):

Well I have so far attempted two tries-:

Code:

head -1 a.txt ; head -3 a.txt | tail -1

But I can't do this even though it works because of the restriction in the problem.

Code:

head -1 a.txt | tee /dev/tty | tail

this does not work and the reason is that after running the head command I get only one line and that is printed (which will be header since it is the first line). But I am unable to get the header and the particular record.

Is there someway I can filter within the tee command ?
