_______________________________________________________________
You can see in the picture below that:
declare -a "$ExecuteThisData"
resulted in executing the string "$ExecuteThisData" without
eval being explicitly invoked. I believe this is unintentional since
this is a variable assignment:
commands to reproduce above:
ExecuteThisData='a=([$(expr 4 - 3)]=$(echo '1ne' | tr '1' 'o'))'
b="$ExecuteThisData"
echo "$b"
echo "$ExecuteThisData"
unset a
declare -a "$ExecuteThisData"
declare -p a
echo ${a[1]}
_______________________________________________________________
Note however that: { declare -a a="$Data" } :
produces the expected result of assigning each space
delimited element to a
separate array element, and does not execute the data.
_____________________________________________
In Summary:
declare -a "$string" # results in execution of $string
declare -a a=($string) # does not result in execution of $string
I can't find the compiler version for bash but it is debian jessie's
compiled version. Your response
would be appreciated.
