Dojo: The Longest Line
HardOne-Liner Dojo10-15 minThe brief
The file /root/prose.txt has lines of different lengths. In ONE line, find the SINGLE longest line and write it (its text only) to /root/answer.txt.
There's no 'longest line' command — you compose one. awk can prefix each line with its length; sort numerically, take the top, then strip the length back off. Spicy, but it's just the pipeline pattern again.
What you'll do
- Write the longest line of /root/prose.txt to /root/answer.txt, in one line
