194. Transpose File
Medium
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.
Example:
If file.txt has the following content:
name age
alice 21
ryan 30
Output the following:
name alice ryan
age 21 30
Solution
# Read from the file file.txt and print its transposed content to stdout.
wordcount=$(head -1 file.txt | wc -w)
col_n=1
while [[ $col_n -le $wordcount ]]; do
awk "{ print \$$col_n }" file.txt | paste -sd " "
col_n=$((col_n + 1))
done
