find fixed/pdf/ -name '*.pdf' -exec sh -c 'pdftotext "{}" - | grep --with-filename --label="{}" --color "Ascend"' \; | 2>&1 dump.txt

Answer 1

You can use: 您可以使用：

find fixed/pdf/ -name '*.pdf' -exec sh -c 'pdftotext "$1" - |
   grep --with-filename --label="$1" --color "Ascend"' - '{}' \; > dump.txt 2>&1

To redirect both stdout and stderr to your file dump.txt . 要将stdout和stderr都重定向到文件dump.txt 。
