printf does not return error on readonly assignment

ng from *bash*. Indeed, trying to use `printf` to assign a value to `$1` for example, does return a error: > bash$ printf -v 1 2 > -bash: `1': not a valid identifier > bash$ echo $? > 2 Repeat-By: > bash$ readonly var=1 > bash$ var=2 > -bash: var: readonly variable > bash$ echo $? > 1 > bash$ printf -v var 2 > -bash: var: readonly variable > echo $? > 0 Sincerely yours, -- Arnaud GAILLARD
