Data Display all the words whose length is equal to the longest word in the text
Hi Guys,

I was going some trial and error to see if I can find the longest word in a text.

I was using Pipes because they are easier to use in this case.
I was stuck on this for a while so I thought I'll get some help with it.

I tried this code to separate all the words in a text in lines and this would give me the LENGTH of the longest word.
Code:
tr -s " .,;" "\n" <random.txt | tr '[A-Z]' '[a-z]' | sort -u | wc -L

But suppose if I want to display the longest word/s according to length (for example, longest word is 15 characters long and I want to display all words with the length of 15 characters).

I tried using this command but doesnt work

Code:
tr -s " .,;" "\n" <random.txt | tr '[A-Z]' '[a-z]' | sort -u | uniq -u
