将目录下的所有Java文件递归转换为4个空格而不是制表符:

find . -type f -name *.java -exec bash -c 'expand -t 4 {} > /tmp/stuff;mv /tmp/stuff {}' \;

我的建议是使用:

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

评论:

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.

使用反斜杠转义sed。

在linux上:

将所有*.txt文件中的所有制表符替换为1个连字符: Sed -i $'s/\t/-/g' *.txt 将所有*.txt文件中的所有制表符替换为1个空格: Sed -i $'s/\t/ /g' *.txt 将所有*.txt文件中的所有制表符替换为4个空格: Sed -i $'s/\t/ /g' *.txt

在mac电脑上:

将所有*.txt文件中的所有制表符替换为4个空格: Sed -i " $'s/\t/ /g' *.txt

在发现混合制表符和空格后，我使用style重新缩进所有的C/ c++代码。如果您愿意，它还可以强制使用特定的括号样式。

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。

没有人提到rpl?使用rpl可以替换任何字符串。 要将制表符转换为空格，

rpl -R -e "\t" "    "  .

非常简单。
