我试图遍历目录并将所有9000左右的pdf文件转换为png
for i in *.pdf; do
pdftoppm -f 1 -l 2 -png $i ${i%.pdf*}
done
该循环仅适用于大约500种情况。当我在一些未转换的pdf文件上手动调用pdftoppm时，它可以工作。
例如，一个在循环中不起作用的文件是w7hnp - FOO BAR 8-18-12 NOT FINAL DOC.pdf。当我使用制表符补全手动调用pdftoppm时，文件名包含转义字符：w7hnp\ -\ FOO\ BAR\ 8-18-12\ NOT\ FINAL\ DOC.pdf，该命令可以正常工作。
有没有办法确保空间正确地逃脱？
我需要保留文件名以与数据库中的其他信息匹配，因此重命名将不起作用，除非我可以使用新旧名称创建字典。

您应引用以下变量：.cat1 {
border: 2px solid blue;
}
.cat2 {
border: 2px solid red;
}和<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
