What is your definition of "highest length"? You say you want multiple lines, does that mean like "Top 5 highest length"? – jesse_b Apr 28 '18 at 14:33

I read it as “if there’s a tie, all the longest lines” – Jeff Schaller Apr 28 '18 at 14:34

No I only want that "line which has higher length among all the lines" and "if there is tie then all the longest line" – Shah Honey Apr 28 '18 at 15:24

"higher" is a comparative word, and as such needs qualification. Do you mean "highest", i.e. the "longest line or joint-longest lines"? – Chris Davies Apr 28 '18 at 15:33

@Shah, if the lines in the file were "ab", "cd", and "e", what is your expected result? – Jeff Schaller Apr 28 '18 at 16:13

1there are other solutions in that question that handle more than one line with max length... in gawk as well as other tools – Sundeep Apr 28 '18 at 16:20

Check length of line (if no arguments passed to the length function it uses $0, the whole line).
Where length is greater than variable x, set x to the length. And set variable a to the contents of the line.
Finally, on reaching end of file, print the contents of variable a.
awk 'length>x{x=length;a=$0}END{print a}' inputfile
