Remove a file's "read only" attribute in vim after editing it and saving with :w!
提问by Somebody still uses you MS-DOS
I want to change the read only attribute from a file when I save it with :w!in vim. How do I do it? (I don't mind if I have to call an external script).
当我:w!在 vim 中保存文件时，我想更改文件中的只读属性。我该怎么做？（我不介意我是否必须调用外部脚本）。
I'm using Linux.
我正在使用 Linux。
I know I can use an external script using this command: autocmd BufWrite /tmp/* !sh /tmp/script.sh. So, I would like to call a chmod command when :w!is invoked: the chmod command is going to be something like this:
我知道我可以使用以下命令使用外部脚本：autocmd BufWrite /tmp/* !sh /tmp/script.sh. 所以，我想在调用时:w!调用 chmod 命令：chmod 命令将是这样的：
autocmd BufWrite <:w! condition> !chmod u+w %
So, how do I do the ":w!" condition? Is it possible or do I need to use another structure?
那么，我该怎么做 ":w!" 健康）状况？有可能还是我需要使用其他结构？

The v:cmdbang is what you are looking for.
v:cmdbang 正是您要找的。
function! g:ChmodOnWrite()
if v:cmdbang
silent !chmod u+w %
endif
endfunction
autocmd BufWrite * call g:ChmodOnWrite()

The shell command chmod u+w <name of file>does what you want. I don't know offhand how to invoke that from inside vim.
shell 命令chmod u+w <name of file>执行您想要的操作。我不知道如何从 vim 内部调用它。

You should be able to use just *:
您应该能够仅使用*：
autocmd BufWrite * !chmod u+w %
It may be better to use BufWriteCmdinstead. I think that if the chmodfails, Vim will not attempt to write.
使用它可能会更好BufWriteCmd。我认为如果chmod失败，Vim 不会尝试写入。
