Bash array of functions

Question

I'm trying to create an array of functions in order to iterate through each function in order.

declare -a FUNCTION
FUNCTION[1]="FUNCTION.A"
FUNCTION[2]="FUNCTION.B"
FUNCTION[3]="FUNCTION.C"

for i in "${!FUNCTION[@]}"; do
  ${FUNCTION[$i]};
done

This just prints out FUNCTION.A and says command not found. I need it to run the function. Suggestions?

Answer 1

Works fine for me.

declare -a FUNCTION
FUNCTION[1]="FUNCTION.A"
FUNCTION[2]="FUNCTION.B"
FUNCTION[3]="FUNCTION.C"

#Define one of the functions
FUNCTION.A() { echo "Inside of FUNCTION.A"; }


$ for i in "${!FUNCTION[@]}"; do   ${FUNCTION[$i]}; done

OUTPUT:

Inside of FUNCTION.A
FUNCTION.B: command not found
FUNCTION.C: command not found

Answer 2

Another way that I think looks a lot better

funcs_to_test=( voltage_force_landing voltage_warn_critical )

for testP in "${funcs_to_test[@]}"
do  
    $testP
done

And make sure to have written your functions above where you call this code
