Longest line in a file

Question

I\'m looking for a simple way to find the length of the longest line in a file. Ideally, it would be a simple bash shell command instead of a script.

Answer 1

Just for fun, here's the Powershell version:

cat filename.txt | sort length | select -last 1

And to just get the length:

(cat filename.txt | sort length | select -last 1).Length
