我的建议是使用:

find . -name '*.lua' -exec ex '+%s/\t/  /g' -cwq {} \;

Use in place editing. Keep backups in a VCS. No need to produce *.orig files. It's good practice to diff the result against your last commit to make sure this worked as expected, in any case. sed is a stream editor. Use ex for in place editing. This avoids creating extra temp files and spawning shells for each replacement as in the top answer. WARNING: This messes with all tabs, not only those used for indentation. Also it does not do context aware replacement of tabs. This was sufficient for my use case. But might not be acceptable for you. EDIT: An earlier version of this answer used find|xargs instead of find -exec. As pointed out by @gniourf-gniourf this leads to problems with spaces, quotes and control chars in file names cf. Wheeler.

警告:这会破坏你的回购。 这将破坏二进制文件，包括那些在svn， .git!使用前请阅读评论!

找到。-iname '*.java' -type f -exec sed -i。/\t/ /g' {} +

原始文件保存为[filename]. trans。

将'*.java'替换为您正在寻找的文件类型的文件结尾。这样可以防止二进制文件的意外损坏。

缺点:

将替换文件中的所有制表符。 如果在这个目录中有一个5GB的SQL转储，将花费很长时间。

你可以使用vim:

find -type f \( -name '*.css' -o -name '*.html' -o -name '*.js' -o -name '*.php' \) -execdir vim -c retab -c wq {} \;

正如Carpetsmoker所说，它将根据你的vim设置重新标签。文件中的modeline(如果有的话)。此外，它不仅将替换行首的制表符。这通常不是你想要的。例如，你可能有文字，包含制表符。

将制表符转换为空格只是在”。Lua " files [tab -> 2个空格]

find . -iname "*.lua" -exec sed -i "s#\t#  #g" '{}' \;

我的建议是使用:

find . -name '*.lua' -exec ex '+%s/\t/  /g' -cwq {} \;

Git存储库友好方法

git-tab-to-space() (
  d="$(mktemp -d)"
  git grep --cached -Il '' | grep -E "${1:-.}" | \
    xargs -I'{}' bash -c '\
    f="${1}/f" \
    && expand -t 4 "$0" > "$f" && \
    chmod --reference="$0" "$f" && \
    mv "$f" "$0"' \
    '{}' "$d" \
  ;
  rmdir "$d"
)

操作当前目录下的所有文件:

git-tab-to-space

仅作用于C或c++文件:

git-tab-to-space '\.(c|h)(|pp)$'

您可能特别需要这个，因为那些讨厌的makefile需要选项卡。

命令git grep——cached -Il ":

只列出被跟踪的文件，所以.git中没有任何内容 不包括目录、二进制文件(将被损坏)和符号链接(将被转换为常规文件)

如在解释:如何列出所有文本(非二进制)文件在一个git仓库?

chmod——reference保持文件权限不变:https://unix.stackexchange.com/questions/20645/clone-ownership-and-permissions-from-another-file不幸的是，我找不到一个简洁的POSIX替代方案。

如果你的代码库有一个疯狂的想法，允许在字符串中使用功能原始制表符，使用:

expand -i

然后一个接一个地浏览所有非行开头的制表符，你可以列出:是否可能为制表符git grep ?
