Looking for examples how to add simple localization to your bash scripts, and how to do testing, this is probably what you need ...

# localization:

http://www.linuxtopia.org/online_books/advanced_bash_scripting_guide/localization.html

# gettext

# step 1: update your strings

# before translation
function version()
{
   echo "Usage:     $0 --help"
   echo "Version:   $version"
   echo "Author:    $author"
   echo "Donation:  $donation"
}

# after translation
function version()
{
   echo $"Usage:     $0 --help"
   echo $"Version:   $version"
   echo $"Author:    $author"
   echo $"Donation:  $donation"
}

# step 2: create some sort of structure for your source
mkdir --parent --verbose locale/nl/LC_MESSAGES/
mkdir --parent --verbose lang

# step 3: check the strings
bash -D pct-scanner-script

# step 4: dump po strings to your directory
bash --dump-po-strings pct-scanner-script > lang/nl.pot

# step 5: try to merge existing po with new updates
# remove duplicated strings by hand or with sed or something else
# awk '/^msgid/&&!seen[$0]++;!/^msgid/' lang/nl.pot > lang/nl.pot.new
msgmerge lang/nl.po lang/nl.pot

# step 5.1: try to merge existing po with new updates
cp --verbose lang/pct-scanner-script-nl.po lang/pct-scanner-script-nl.po.old
awk '/^msgid/&&!seen[$0]++;!/^msgid/' lang/pct-scanner-script-nl.pot > lang/pct-scanner-script-nl.pot.new
msgmerge lang/pct-scanner-script-nl.po.old lang/pct-scanner-script-nl.pot.new > lang/pct-scanner-script-nl.po

# step 5.2: try to merge existing po with new updates
touch lang/pct-scanner-script-process-nl.po lang/pct-scanner-script-process-nl.po.old
awk '/^msgid/&&!seen[$0]++;!/^msgid/' lang/pct-scanner-script-process-nl.pot > lang/pct-scanner-script-process-nl.pot.new
msgmerge lang/pct-scanner-script-process-nl.po.old lang/pct-scanner-script-process-nl.pot.new > lang/pct-scanner-script-process-nl.po

# step 6: create .mo file
msgfmt -o locale/nl/LC_MESSAGES/pct-scanner-script.mo lang/nl.po

# step 7: move single .mo file to system locales
sudo cp --verbose locale/nl/LC_MESSAGES/pct-scanner-script.mo /usr/share/locale/nl/LC_MESSAGES/
sudo chown root:root /usr/share/locale/nl/LC_MESSAGES/pct-scanner-script.mo
sudo chmod 644 /usr/share/locale/nl/LC_MESSAGES/pct-scanner-script.mo
sudo ls -hal /usr/share/locale/nl/LC_MESSAGES/pct-scanner-script.mo

# step 8: move all .mo files to system locales
sudo cp --verbose --recursive locale/* /usr/share/locale/
sudo chown root:root /usr/share/locale/nl/LC_MESSAGES/pct-scanner-script.mo
sudo chmod 644 /usr/share/locale/nl/LC_MESSAGES/pct-scanner-script.mo
sudo ls -hal /usr/share/locale/nl/LC_MESSAGES/pct-scanner-script.mo

# step 9: add the following to you bash script under #!/bin/bash
TEXTDOMAINDIR=/usr/share/locale
TEXTDOMAIN=pct-scanner-script

# step 10: start testing

LANG=nl_NL
bash pct-scanner-script --version

LANG=en_GB
bash pct-scanner-script --version
