shell/TransposeFile.sh

#!/usr/bin/env bash

#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

# Read from the file file.txt and print its transposed content to stdout.
