How does an empty string in a file return a line break?

For example, there are such strings in the file:

A.txt

Rei9aiwe bohth4Zu Go3eimum iChieSh5iveeSh2J eiziV0bo lu2Efooz feey5Ohr

To convert into the following situation:

B.txt

Rei9aiwebohth4ZuGo3eimumiChieSh5iveeSh2JeiziV0bolu2Efoozfeey5Ohr

How to do?

Language is not limited, Php/ruby/python can.

Language is not limited, Php/ruby/python can.

sed 's/\s\+/\n/g' a.txt > b.txt

Or

tr ' ' '\n' < a.txt > b.txt

or in Python:

python -c 'open("b.txt", "w").write(open("a.txt").read().replace(" ", "\n"))'

Such a task, more than a line of code is really too wasteful.

Since the language is not limited, to an alternative, visual inspection not a few know what language

Import["a.txt"]~StringReplace~(" " -> "\n") // Export["b.txt", #] &

Add a ruby version

open("b.txt", "w").puts open('a.txt').read.gsub " ", "\n"

Python

myfile = open("a.txt")temp = ""for line in myfile.readlines():    for a in line.split():         temp +=  a + '\n'myfile.close()file_object = open('b.txt', 'w')file_object.writelines(temp)file_object.close()
