我尝试使用 lilypond、latex 和 sejda-console（用于 pdf 部分）编写用于生成歌曲集的包装脚本。到目前为止一切正常，但我对 sejda 有一个问题，这让我很生气。这是我的代码的相关部分：
for %%i in (%f%) do (
sejda-console.bat extractbybookmarks -f ".\%%~ni.pdf" -o "export\%%~ni\%title%.pdf" -l 2 -p [BOOKMARK_NAME] -e "%title%" --overwrite
)
其中 f 是“;” - 分隔的文件列表。此命令适用于第一个文件，但对所有其他文件都无效。我找不到 sejda 收到的命令之间的任何区别。这是我的控制台输出：
make_sheet.bat -t "Live it up" --supress *.lytex

更糟糕的是，如果我复制 sejda 接收的命令并将它们粘贴为新命令的参数，一切正常。我怀疑两者之间的工作目录发生了一些事情，但我不明白。
另外，请注意，尽管 echo 已关闭，但输出包括用于后续通过 for 循环的命令（以“(sejda-console.bat ...”开头）。但是，它不包括在第一次运行中。
我不是编程专家，尤其是批处理方面的专家，非常感谢任何帮助。
