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
awk '{for(i=1;i<=NF;i++){if(NR==1){s[i]=$i;}else{s[i]=s[i]" "$i; }}}END{for(i=1;s[i]!="";i++){print s[i]}}' file.txt
