linux - unix shell set command -

-

want know set -a option in below command? 

 xmloutfile=${xmloutdir}/${test_id}  set -a files "${xmloutfile}"

set -a korn shell (ksh) specific (not available in bash or posix sh) , initializes array specified value(s).

here's example:

$ set -a colors "red" "green" "blue" $ print ${colors[0]} red $ print ${colors[1]} green $ print ${colors[2]} blue

in example, ${files[0]} set $xmloutfile.

instead of using set -a can use example array[0]="value" more portable.
