英文:
Conditional removing of text using sed
问题
以下是您要的翻译结果：
我有这个文件：
HEADER2023053112460600000004000000000.000002023053112364820230531123707

我需要删除第二列的第11和第12个字符，如果它们分别匹配3和4。
我能想到的最好的方法是这样的：
sed -E 's/^([^[:blank:]]+[[:blank:]]+)([^[:blank:]]{10})(34)([^[:blank:]]+)[[:blank:]]+/ /' 文件名
它几乎能够得到期望的结果。问题是第三列和第四列之间的间距：被替换的行干扰了原始的空格数量，我需要保持完全相同的空格。
希望对您有所帮助。

And I need to remove the 11th and 12th characters on the second column if they both match 3 and 4 respectively.
The best I could came up with is this:
sed -E 's/^([^[:blank:]]+[[:blank:]]+)([^[:blank:]]{10})(34)([^[:blank:]]+)[[:blank:]]+/\1\2\4 /' file
HEADER2023053112460600000004000000000.000002023053112364820230531123707

Which almost gets the desired result. Problem is the spacing between the third and fourth column: the lines that got replaced messed with the original number of spaces and I need it to be the exact same thing.
Any help would be most welcome.
