Question

Using bash, I have a list of strings that I want to use to replace an int. Here’s an example:

day1=Monday
day2=Tuesday
day3=Wednesday
day4=Thursday
day5=Friday
day6=Saturday
day7=Sunday

If I have an int, $dow, to represent the day of the week, how do I print the actual string? I tried this:

echo ${day`echo $dow`}

but get error of “bad substitution”. How do I make this work? Note: I can change the $day variables to a list or something.

Answer 1

Yes, it would be easiest to do this as an array:

day=([1]=Monday [2]=Tuesday ...)
echo "${day[dow]}"
