Question

我有很多tif文件（1页= 1个tif文件），我想将它们转换为单个，多重，大的tif，然后在其上启动tesseract（对于ocr）并获得pdf作为结果。< / p>

我的文件以这种方式命名：

    $ ls
    115_XRTL_000_001.tif  115_XRTL_000_004.tif  115_XRTL_000_007.tif  115_XRTL_000_010.tif
    115_XRTL_000_002.tif  115_XRTL_000_005.tif  115_XRTL_000_008.tif  115_XRTL_000_011.tif
    115_XRTL_000_003.tif  115_XRTL_000_006.tif  115_XRTL_000_009.tif

我使用以下代码：

    for f in *.tif; do base=${f%_*}; tiffcp $base* ../pdfs/$base.tif; tesseract ../pdfs/$base.tif -l fra ../pdfs/$base pdf; rm -v ../pdfs/$base.tif; done

除了带有tesseract的部分外，它的效果很好。它创建了一个循环，并且tesseract在同一个大的tif文件上无法工作。

日志：

$ for f in *.tif; do base=${f%_*}; tiffcp $base* ../../pdfs/$base.tif; tesseract ../../pdfs/$base.tif -l fra ../../pdfs/$base pdf; rm -v ../../pdfs/$base.tif; done

如何阻止循环？

另一个问题是tif文件位于不同的文件夹中。

例如，如果我带两个文件夹（我有更多）：

$ ls -R
.:
115_XRTL_000  128_XRTL_001

./115_XRTL_000:
115_XRTL_000_001.tif  115_XRTL_000_004.tif  115_XRTL_000_007.tif  115_XRTL_000_010.tif
115_XRTL_000_002.tif  115_XRTL_000_005.tif  115_XRTL_000_008.tif  115_XRTL_000_011.tif
115_XRTL_000_003.tif  115_XRTL_000_006.tif  115_XRTL_000_009.tif

./128_XRTL_001:
128_XRTL_001_001.tif  128_XRTL_001_005.tif  128_XRTL_001_009.tif  128_XRTL_001_013.tif
128_XRTL_001_002.tif  128_XRTL_001_006.tif  128_XRTL_001_010.tif  128_XRTL_001_014.tif
128_XRTL_001_003.tif  128_XRTL_001_007.tif  128_XRTL_001_011.tif
128_XRTL_001_004.tif  128_XRTL_001_008.tif  128_XRTL_001_012.tif

我希望能够启动一个命令，该命令将递归地应用于每个文件夹，并为每个文件夹创建一个pdf（带有ocr）（在../pdfs/文件夹中移动）。
