扩展示例函数时出现 bash 脚本问题

我正在使用abcde（更好的 CD 编码器）和我的树莓派，并想使用搜索和嵌入专辑封面的新功能。为此，有abcde.conf一个部分可以让你定义自己的post_encode ()函数。

来自的一个工作示例http://www.andrews-corner.org/getalbumart.html看起来像这样：

#--------------------------------------------------------------------------#
#  A post_encode function to embed album art downloaded with abcde 2.7     #
#  and greater using the new getalbumart function. OUTPUTTYPE must be      # 
#  mp3 and and tagging is with eyeD3. To use this function copy the        # 
#  entire code block and paste it into your ~/.abcde.conf file.            #
#                                                                          # 
#                abcde: Downloading Album Art...                           #
#         http://www.andrews-corner.org/getalbumart.html                   #
#--------------------------------------------------------------------------#
post_encode ()
{
ARTISTFILE="$(mungefilename "$TRACKARTIST")"
ALBUMFILE="$(mungefilename "$DALBUM")"

if [ "$VARIOUSARTISTS" = "y" ] ; then
FINDPATH="$(eval echo "$VAOUTPUTFORMAT")"
else
FINDPATH="$(eval echo "$OUTPUTFORMAT")"
fi

FINALDIR="$(dirname "$OUTPUTDIR/$FINDPATH")"
cd "$FINALDIR"

if [ "$OUTPUTTYPE" = "mp3" ] && [ "$TAGGER" = "$EYED3" ] ; then
vecho "Preparing to embed the album art..." >&2
else
vecho "Not embedding album art, you need mp3 output and eyeD3 tagging..."  >&2
return 1
fi

if [ -e "cover.jpg" ] ; then
for i in *.mp3
do
eyeD3 --add-image cover.jpg:FRONT_COVER "$i"
done

mkdir backup
mv cover.jpg backup
vecho "Your files have had the album art embedded..." >&2
else
vecho "No album art found so no image embedded..." >&2
fi
}

我希望能够一次性对几种格式执行此操作（abcde 的优势之一），但无法通过一个函数实现全部操作。

这是我的失败的尝试制作一个post_encode ()功能：

post_encode ()
{
ARTISTFILE="$(mungefilename "$TRACKARTIST")"
ALBUMFILE="$(mungefilename "$DALBUM")"

if [ "$VARIOUSARTISTS" = "y" ] ; then
FINDPATH="$(eval echo "$VAOUTPUTFORMAT")"
else
FINDPATH="$(eval echo "$OUTPUTFORMAT")"
fi

FINALDIR="$(dirname "$OUTPUTDIR/$FINDPATH")"
cd "$FINALDIR"

if [[ "$OUTPUTTYPE" == *"mp3"* ]] && [ "$TAGGER" = "$EYED3" ] ; then
vecho "Preparing to embed the album art..." >&2
else
vecho "Not embedding album art, you need mp3 output and eyeD3 tagging..." >&2
return 1
fi

if [ -e "cover.jpg" ] ; then
for i in *.mp3
do
eyeD3 --add-image cover.jpg:FRONT_COVER "$i"
done

if [[ "$OUTPUTTYPE" == *"flac"* ]] ; then
vecho "Preparing to embed the album art..." >&2
else
vecho "Not embedding album art, you need flac output.." >&2
return 1
fi

if [ -e "cover.jpg" ] ; then
for i in *.flac
do
metaflac --import-picture-from=cover.jpg "$i"
done

mkdir backup
mv cover.jpg backup
vecho "Your files have had the album art embedded..." >&2
else
vecho "No album art found so no image embedded..." >&2
fi
}

以下是关于跑步的抱怨abcde：

pi@EMK-RPi2B ~ $ abcde
/etc/abcde.conf: line 512: syntax error at unexpected word `}'
/etc/abcde.conf: line 512: `}'
^[Grabbing entire CD - tracks01 02 03 04 05 06 07 08 09 10 11 12 13 14 15

我在这里做错了什么？那里只有一{}对匹配的，对第 512 行的投诉是关于}上面的最后一个...

更正此问题：

if [ -e "cover.jpg" ] ; then
for i in *.mp3
do
eyeD3 --add-image cover.jpg:FRONT_COVER "$i"
done

在：

if [ -e "cover.jpg" ] ; then
for i in *.mp3
do
eyeD3 --add-image cover.jpg:FRONT_COVER "$i"
done
fi
