问题


The way you Git ignore watching/tracking a particular dir/file. you just run this:

git update-index --assume-unchanged <file>

Now how do you undo it so they are watched again? (Let's call it un-assume.)


回答1:


To get undo/show dir's/files that are set to assume-unchanged run this:

git update-index --no-assume-unchanged <file>

To get a list of dir's/files that are assume-unchanged run this:

git ls-files -v|grep '^h'

If this is a command that you use often - you may want to consider having an alias for it as well. Add to your global .gitconfig:

[alias]
    hide = update-index --assume-unchanged
    unhide = update-index --no-assume-unchanged

How to set an alias (if you don't know already):

git config --configLocation alias.aliasName 'command --options'

Example:

git config --global alias.hide 'update-index --assume-unchanged'
git config... etc

After saving this to your .gitconfig, you can run a cleaner command.

git hide myfile.ext

or

git unhide myfile.ext

This git documentation was very helpful.

As per the comments, this is also a helpful alias to find out what files are currently being hidden:

[alias]
    hidden = ! git ls-files -v | grep '^h' | cut -c3-

git update-index function has several option you can find typing as below:

git update-index --help

Here you will find various option - how to handle with the function update-index.

[if you don't know the file name]

git update-index --really-refresh 

[if you know the file name ]

git update-index --no-assume-unchanged <file>

will revert all the files those have been added in ignore list through.

git update-index --assume-unchanged <file>



回答4:


I assume (heh) you meant --assume-unchanged, since I don't see any --assume-changed option. The inverse of --assume-unchanged is --no-assume-unchanged.

To synthesize the excellent original answers from @adardesign, @adswebwork and @AnkitVishwakarma, and comments from @Bdoserror, @Retsam, @seanf, and @torek, with additional documentation links and concise aliases...

Basic Commands

To reset a file that is assume-unchanged back to normal:

git update-index --no-assume-unchanged <file>

To list all files that are assume-unchanged:

git ls-files -v | grep '^[a-z]' | cut -c3-

To reset all assume-unchanged files back to normal:

git ls-files -v | grep '^[a-z]' | cut -c3- | xargs git update-index --no-assume-unchanged --

Note: This command which has been listed elsewhere does not appear to reset all assume-unchanged files any longer (I believe it used to and previously listed it as a solution):

git update-index --really-refresh

Shortcuts

To make these common tasks easy to execute in git, add/update the following alias section to .gitconfig for your user (e.g. ~/.gitconfig on a *nix or macOS system):

[alias]
    hide = update-index --assume-unchanged
    unhide = update-index --no-assume-unchanged
    unhide-all = ! git ls-files -v | grep '^[a-z]' | cut -c3- | xargs git update-index --no-assume-unchanged --
    hidden = ! git ls-files -v | grep '^[a-z]' | cut -c3-



回答6:


If you want to undo all files that was applied assume unchanged with any status, not only cached (git marks them by character in lower case), you can use the following command:

git ls-files -v | grep '^[a-z]' | cut -c 3- | tr '\012' '\000' | xargs -0 git update-index --no-assume-unchanged
  1. git ls-files -v will print all files with their status
  2. grep '^[a-z]' will filter files and select only assume unchanged
  3. cut -c 3- will remove status and leave only paths, cutting from the 3-rd character to the end
  4. tr '\012' '\000' will replace end of line character (\012) to zero character (\000)
  5. xargs -0 git update-index --no-assume-unchanged will pass all paths separated by zero character to git update-index --no-assume-unchanged to undo



回答7:


Adding to @adardesign's answer, if you want to reset all files that have been added to assume-unchanged list to no-assume-unchanged in one go, you can do the following:

git ls-files -v | grep '^h' | sed 's/^..//' | sed 's/\ /\\ /g' | xargs -I FILE git update-index --no-assume-unchanged FILE || true

This will just strip out the two characters output from grep i.e. "h ", then escape any spaces that may be present in file names, and finally || true will prevent the command to terminate prematurely in case some files in the loop has errors.




回答8:


If you are using Git Extensions, then follow below steps:

  1. Go to commit window.
  2. Click on the dropdown named Working directory changes.
  3. Select Show assummed-unchanged files option.
  4. Right click on the file you want to unassumme.
  5. Select Do no assumme unchanged.

You are done.




回答9:


Nothing here that is not covered. But would like to add my 2 cents. At times, I run a build and it changes lot of files and then I want to work on something, so this command really helps me a lot.

git update-index --assume-unchanged `git status | grep modified | sed 's|modified:||g'| xargs`

Hope someone else find it useful as well.
