Obtaining origin approvals on a documents within vi?

Usually while editing and enhancing config documents, I'll open one with vi and afterwards when I most likely to wait understand that I really did not type

sudo vi filename

Exists any kind of means to offer vi sudo advantages to conserve the documents? I appear to remember seeing something concerning this while seeking out some things concerning vi a while earlier, today I can not locate it.

When you enter into insert setting on a documents you require sudo accessibility to modify, you get a standing message claiming

-- INSERT -- W10: Warning: Changing a readonly file

If I miss out on that, usually I do

:w ~/edited_blah.tmp
:q

. after that.

sudo "cat edited_blah.tmp > /etc/blah"

. or.

sudo mv edited_blah.tmp /etc/blah

There is possibly a much less periphrastic means to do it, yet it functions.

A fast hack you can take into consideration is doing a chmod on the documents you're editing and enhancing, conserve with strength, and afterwards chmod back to what the documents was initially.

ls -l test.file (to see the permissions of the file)
chmod 777 test.file
[This is where you save in vim]
chmod xxx test.file (restore the permissions you found in the first step)

Of training course I do not advise this strategy in a system where you're bothered with security, when it comes to a couple of secs any person can read/change the documents without you understanding.

A fast Google appears to offer this suggestions :

  1. Don't attempt to modify if it's read - just.
  2. You could be able to transform the approvals on the documents. (Whether or not it will certainly allow you conserve depends on trial and error.)
  3. If you still modified anyhow, conserve to a short-lived documents and afterwards relocate.

Ryan's suggestions is usually excellent, nonetheless, if adhering to action 3, do not relocate the short-lived documents ; it'll have the incorrect possession and also approvals. Rather, sudoedit the proper documents and also read in the materials (making use of :r or such) of the short-lived documents.

If adhering to action 2, make use of :w! to compel the documents to be created.

In basic, you can not transform the reliable customer id of the vi procedure, yet you can do this :

:w !sudo tee myfile
