Using variables defined in other bash scripts

Question

I have a bash script where I define UTF-8 Greek Symbols in a file named greek-utfb.sh. I want to run tests that display the variables for printing the greek letters in the file greek-utfb-scout.

--- greek-utfb.sh ----
utfb-greek ()
{
  Alph="\u0391"   # Alpha
  Beta="\u0392"   # Beta
  Gamm="\u0393"   # Gamma
  Delt="\u0394"   # Delta
  Epsi="\u0395"   # Epsilon
}
--- greek-utfb-scout.sh ---
greek-utf-scout ()
{
  echo -e "Alph: $Alph"
  echo -e "Beta: $Beta"
  echo -e "Gamm: $Gamm"
  echo -e "Delt: $Delt"
  echo -e "Epsi: $Epsi"
}

What do I have to add in greek-utfb-scout.sh to be able to translate the greek variables in greek-utfb.sh.

Answer 1

First, don't put the variable definitions inside a function. Instead, change greek-utfb.sh to look like this:

#!/bin/sh
Alph="\u0391"   # Alpha
Beta="\u0392"   # Beta
Gamm="\u0393"   # Gamma
Delt="\u0394"   # Delta
Epsi="\u0395"   # Epsilon

Now source this file in greek-utfb-scout.sh:

#!/bin/sh
. greek-utfb.sh
greek-utf-scout ()
{
  echo -e "Alph: $Alph"
  echo -e "Beta: $Beta"
  echo -e "Gamm: $Gamm"
  echo -e "Delt: $Delt"
  echo -e "Epsi: $Epsi"
}

After running . greek-utfb-scout.sh, the function now works as expected:

$ . greek-utfb-scout.sh
$ greek-utf-scout
Alph: Α
Beta: Β
Gamm: Γ
Delt: Δ
Epsi: Ε
