problem using nested parallel

[Shantanu Unknown]

Hi,

I am probably doing something dumb , but I couldn't figure it out

I have a bunch of directory names in a file and I want to print out the directory names appended with some numbers.

So I do

cat filename|  seq 19 22 | parallel -j1  echo "{1}/output/{2}"

and for each row of contents of filename I want

<filenamecontent>/output19

<filenamecontent>/output20

<filenamecontent>/output21

<filenamecontent>/output22

However this is not working. What am I doing wrong? I am using tcsh(but same problem also happens in bash shell)

Instead what I get is just {1}/output{2} 19

     {1}/output{2} 20 and so on

I also replaced parallel  with parallel -N2

Thanks
