アプリケーションソースコードのスクリプト

次のサンプルソースコードは、画面に「Hello World」と出力し、UEFIシェルバージョンと環境変数を表示するUEFIシェルアプリケーションを実装する方法を示しています。このスクリプト例では、すべてのFS*:ファイルシステム（FS0、FS1、FS2）をループして、特定の入力ファイル（この場合、sysconfig_backup.txt）を検索します。

エクスポート例：

fs0:\> 

@echo -off
cls
set -v myfs 0
if exist FS0:\* then
FS0:
echo "FS0:\ Found!"
goto FSFOUND
endif
echo "FS0:\ not found in system"
echo "Going to search first available file system from FS1, FS2,..., FS100"
pause
for %a run (1 100)
set -v myfs %a
if exist FS%myfs%:\* then
FS%myfs%:
echo "FS%myfs%:\ Found!"
goto FSFOUND
endif
endfor
## No valid FS found in system, so exit now
echo "No valid File System (FS0, FS1,..., FS100) found in system"
goto END
:FSFOUND
if exist sysconfig_backup.txt then
echo ===========================================================================
echo "%cwd%sysconfig_backup.txt already exists! Continuing the execution of the"
echo "script will remove existing sysconfig_backup.txt file and create a new"
echo "latest system configuration sysconfig_backup.txt file."
echo ===========================================================================
pause
rm sysconfig_backup.txt
endif
echo "Saving latest system configuration in sysconfig_backup.txt file."
sysconfig -export sysconfig_backup.txt
:END
set -d myfs

インポート例：

fs0:\> 

@echo -off
cls
set -v myfs 0
if exist FS0:\sysconfig_backup.txt then
FS0:
echo "FS0:\sysconfig_backup.txt Found!"
goto FSFOUND
endif
echo ===========================================================================
echo "FS0:\sysconfig_backup.txt not found in system"
echo "Going to search sysconfig_backup.txt from all available file system"
echo "from FS1, FS2,..., FS100"
echo ===========================================================================
pause
for %a run (1 100)
set -v myfs %a
if exist FS%myfs%:\sysconfig_backup.txt then
FS%myfs%:
echo "FS%myfs%:\sysconfig_backup.txt Found!"
goto FSFOUND
endif
endfor
## No valid sysconfig_backup.txt found in system, so exit now
echo "No valid sysconfig_backup.txt found from File System (FS0, FS1,..., FS100)"
goto END
:FSFOUND
if exist sysconfig_backup.txt then
echo ===========================================================================
echo "%cwd%sysconfig_backup.txt Found! Continuing the execution of the script"
echo "will cause system to override previous configuration and use the"
echo "configuration settings stored in sysconfig_backup.txt file."
echo ===========================================================================
pause
sysconfig -import sysconfig_backup.txt
endif
:END
set -d myfs
