How to read any number of inputs from user at once and store it into an array. For example this will read only a single input at a time
read -p "Please enter username: " username
echo "Dear $username,"
I want something like:
read -p "Please enter location names separated by space: "
How would i store location names into an array and then loop through it.
try this:
#!/bin/bash
read -r -p "Please enter location names separated by space: " -a arr
for location in "${arr[@]}"; do
echo "$location"
done
read in Bash has had the -a option for a very long time, so I suspect that you are running the code with another shell, possibly Dash. If you run the code with bash script.sh, or make the program executable and run it with ./script.sh, it should work unless you are using a decades-old version of Bash. You can't do what you want with Dash because it doesn't support arrays. See Does dash support bash style arrays?.read -p "Please enter location names separated by space: " location_names
for location in $location_names
do
echo $location
done
Testing.
Please enter location names separated by space: paris london new-york
paris
london
new-york
