so I am currently displaying the last line of a csv file using tail -n 1 file1.csv. That results in the values being displayed in one line just separated by commas. I want to be able to display a few select values by doing this echo "Value 3: $VALUES[2]"
. So put the result of tail into an array VALUES and then be able to pick what values I want to display.
With mapfile
which is a bash4+ feature
#!/usr/bin/env bash
mapfile -td, VALUES < <(tail -n 1 file1.csv)
for i in "${!VAlUES[@]}"; do
echo "$i" "${VALUES[$i]}"
done
If mapfile
is not available.
#!/usr/bin/env bash
IFS=, read -ra VALUES < <(tail -n 1 file1.csv)
for i in "${!VAlUES[@]}"; do
echo "$i" "${VALUES[$i]}"
done
I want to be able to display a few select values by doing this echo "Value 3: $VALUES[2]"
echo "Value 3: ${VALUES[2]}"
