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

尝试命令行工具expand。

expand -i -t 4 input | sponge output

在哪里

-i用于只展开每行的前导制表符; -t 4表示每个制表符将转换为4个空格字符(默认为8个)。 Sponge来自moreutils包，避免清除输入文件。在macOS上，moreutils包可以通过Homebrew (brew install moreutils)或MacPorts (sudo port install moreutils)获得。

最后，在使用Homebrew (brew install coreutils)或MacPorts (sudo port install coreutils)安装coreutils之后，可以在macOS上使用gexpand。

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" '{}' \;

在其他答案中建议的使用expand似乎是仅用于此任务的最合乎逻辑的方法。

也就是说，它也可以用Bash和Awk来完成，以防你想在它的同时做一些其他的修改。

如果使用Bash 4.0或更高版本，shopt内置的globstar可以使用**进行递归搜索。

在GNU Awk 4.1或更高版本中，sed可以像“inplace”一样修改文件:

shopt -s globstar
gawk -i inplace '{gsub("\t","    ")}1' **/*.ext

如果你想设置每个制表符的空格数:

gawk -i inplace -v n=4 'BEGIN{for(i=1;i<=n;i++) c=c" "}{gsub("\t",c)}1' **/*.ext

您可以使用find与制表符到空格包。

首先，安装制表符到空格

npm install -g tabs-to-spaces

然后，从项目的根目录运行这个命令;

find . -name '*' -exec t2s --spaces 2 {} \;

这将把每个文件中的每个制表符替换为2个空格。

我的建议是使用:

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