Using awk to align columns in text file?

Question

Would awk be useful to convert \"Input\" to \"Desired output\"?

Input

testing speed of encryption
test 0 (64 bit key, 1         


        

Answer 1

A trick to align right using column is to use rev:

$ head -1 file; tail -n+2 file | rev | column -t | rev
