Answer / srinivas
Buddies here is the correct answer assume file.txt is the input file then the command would be
cat file.txt | tr "\n" ","
what above command will do is on the input (which is 3 columns each having "\n" at the end) it will replace set1 ("\n" in this case) with set2 ("," in this case).

Answer / b k roy
Suppose they are asking for displaying just one of the
columns in a directory, make a note of that column number
as it appears when we do a ls -lrt. Then we can use awk to
just display the one columns as o/p.
If column number is n, then do this:
ls -lrt | awk '{print $n}'
