我的实际版本的pdfgrep(1.3.0)允许以下:

pdfgrep -HiR 'pattern' /path

当执行pdfgrep——help时:

H:打印每个匹配项的文件名。 i:忽略大小写区别。 R:递归搜索目录。

它在我的Ubuntu上运行得很好。

如果你想用pdftotext查看文件名，使用以下命令:

find . -name '*.pdf' -exec echo {} \; -exec pdftotext {} - \; | grep "pattern\|pdf" 

谢谢所有的好主意!

我尝试了xargs方法，但正如这里所指出的，xargs将使它不可能(或非常困难)包括打印实际的文件名……

所以我尝试了GNU并行。

parallel "pdftotext -q {} - | grep --with-filename --label='['{}']' --color=always --context=5 'pattern'" ::: *.pdf

This prints not only the pattern, but with --context=5 also 5 lines above and below as well for context. With -q pdftotext won't print any error messages or warnings (quiet). I use brackets [] as labels instead of braces {}. If you wanted braces --label='{'{}'}' will make that happen. Note that {} is replaced by the actual filename by GNU parallel, e.g. 'Example portable document file name with spaces.pdf' ({} is already using single quotes '). By using --label={} only the filename will be printed, which may be the favored way of displaying the filename. I also noticed that the output was without color when I tried it, except when forcing it by adding --color=always with grep. It may be useful to add --ignore-case to the grep command for a case-insensitive keyword search.

如果所有PDF文件都应该递归处理，包括当前目录(.)中的所有子目录，这可以通过find来完成:

find . -type f -iname '*.pdf' -print0 | parallel -0 "pdftotext -q {} - | grep --with-filename --label='['{}']' --color=always --context=5 'pattern'"

With find, -iname '*.pdf' acts case-insensitive. With -name '*.pdf' only lower-case .pdf files will be included (the normal case). Since I sometimes also encountered Windows PDF-files with an upper-case .PDF file extension, I tend to prefer -iname... The above command also works with the -print find option (instead of -print0), so it will be line-based (one file name per line), then -0 (NUL delimiter) must be omitted from the parallel command. Again, including --ignore-case in the grep command will make the search case-insensitive.

作为处理整个命令行的一般建议，parallel -dry-run将打印将要执行的命令。

$ find . -type f -iname '*.pdf' -print0 | parallel --dry-run -0 "pdftotext -q {} - | grep --with-filename --label='['{}']' --color=always --ignore-case --context=5 'pattern'"
pdftotext -q ./test PDF file 1.pdf - | grep --with-filename --label='['./test PDF file 1.pdf']' --color=always --ignore-case --context=5 'pattern'
pdftotext -q ./subdir1/test PDF file 2.pdf - | grep --with-filename --label='['./subdir1/test PDF file 2.pdf']' --color=always --ignore-case --context=5 'pattern'
pdftotext -q ./subdir2/test PDF file 3.pdf - | grep --with-filename --label='['./subdir2/test PDF file 3.pdf']' --color=always --ignore-case --context=5 'pattern'

我的实际版本的pdfgrep(1.3.0)允许以下:

pdfgrep -HiR 'pattern' /path

当执行pdfgrep——help时:

H:打印每个匹配项的文件名。 i:忽略大小写区别。 R:递归搜索目录。

它在我的Ubuntu上运行得很好。

首先将所有pdf文件转换为文本文件:

for file in *.pdf;do pdftotext "$file"; done

然后像往常一样使用grep。这是特别好的，因为当您有多个查询和许多PDF文件时，它是快速的。

还有pdfgrep，它做的正是它的名字所暗示的。

pdfgrep -R 'a pattern to search recursively from path' /some/path

我用它做过简单的搜索，效果很好。

(Debian、Ubuntu和Fedora中都有软件包。)

从1.3.0版本开始，pdfgrep支持递归搜索。这个版本从Ubuntu 12.10 (Quantal)开始在Ubuntu中可用。
