#
# Given a text file file.txt, transpose its content.
#
# You may assume that each row has the same number of columns and each field is separated by the ' ' character.
#
# For example, if file.txt has the following content:
#
# name age
# alice 21
# ryan 30
#
# Output the following:
#
# name alice ryan
# age 21 30

#!/bin/sh
# Read from the file file.txt and print its transposed content to stdout.
