Shell | Array is separating elements containing spaces -


i have file containing records like

abc def, pqrm, tuv<linebreak> qwe ett, tyr, rty<line break> asd fgh, ghj, lkj<line break>

i have created array first column in above file below ``

tokenname= ($( awk 'begin {fs = ","}; {print $1}' <filename> ))

now when accessing element using 

for tname in "${tokenname[@]}"     echo $tname done

i expecting output 

abc def qwe ett asd fgh

but printing output 

abc  def qwe  ett asd  fgh

please suggest how can resolved

shell expansion happen on whitespace. can avoid awk , in shell looping through file line line , appending first column in array:

arr=()  while ifs=, read -r c1 _;    arr+=("$c1") done < file

then test output array:

declare -p arr # running should emit following line output: declare -a arr='([0]="abc def" [1]="qwe ett" [2]="asd fgh")'
