I have Array of 3 elements and I retrieve these elements in for loop and perform some command on it.
and I want to store the output in single array. How can I do that?
Array1 contains
[ /home/users/abc /home/users/pqr /home/users/xyz]
I want to perform
declare -a product_array
IFS=":"
read -ra ADDR <<< "$Array1"
for i in "${ADDR[@]}"; do
DIR=${i}/aaa/deployment/traces/
product_array=( $(product_array) $(ls $DIR) )
done
I want to store everything in product_array.
The syntax
$(product_array)
is completely wrong here; it will try to run product_array as a command and interpolate its output (command substitution). You are looking for
"${product_array[@]}"
which interpolates the array of this name with proper quoting.
Though you should also avoid the undesired or outright dangerous side effects of the ls command; on the whole, you seem to simply want
for dir in "${Array1[@]}"; do
product_array+=("$dir"/*)
done
You should also avoid upper case for your private variable names; all-uppercase is reserved for system variables.
I'm still fairly new to arrays in Bash, but I just got this to work without a for loop
a="1 2 3 4"
b="a b c d"
test=($(echo $a))
echo ${test[*]}
1 2 3 4
test+=($(echo $b))
echo ${test[*]}
1 2 3 4 a b c d
