Re: print N times

 In bourne-/bash-shell and with GNU sed you could do:
 

 N=${1:-4}

 echo 'abcd' |

 sed -e "
    /\n/q

    h
    :loop
       G
       s/\n/&/$N
    Tloop
    /\n.*\n/D
    P;d
 "
 

 If GNU sed not there, then we need to resort to the "t"/"b" combo, like as
 

 in place of the Tloop use these three constructs as is:
 

 tend
 bloop
 :end
