英文:
git diff must compare only from a certain offset or char. column in a line
问题
以下是翻译后的内容：
如何在git diff中仅从某一行中的特定偏移列进行比较，例如下面的两个日志应该没有区别：
index 7e2d6d7..cb88ce6
--- a/var/log/lightdm/lightdm.log
+++ b/mnt/OSraw/var/log/lightdm/lightdm.log

你正在寻找textconv的差异。虽然文档中说它用于查找二进制文件的差异，但这里所谓的“二进制”实际上指的是在其原始形式下难以处理的任何内容。
echo lightdm.log diff=myfilter >> .git/info/attributes
上述的sed命令会在差异查看它们之前从行中去除前面的括号括起的单词，只是在初始列上涂白了一定数量的列，你可以像这样做：s,..........,----------,。
英文:
You're looking for textconv diffs. While the docs say it's for diffing binaries, what "binary" means here is really just anything that's difficult to work with in its original form.
git config diff.myfilter.textconv "sed 's,^\\[[^]]*] , ,'"
echo lightdm.log diff=myfilter >> .git/info/attributes
that sed strips leading bracketed words off the lines before the diff sees them, to just white out a fixed number of initial columns you'd do something like s,..........,----------,.
