Aliases<\/h2>\n

But who can remember that\u2026
Some handy git aliases without update-index<\/code> nightmarish syntax to be put in your ~\/.gitconfig<\/code>:<\/p>\n

[alias]\n    # Usage: git assume fileName\n    assume = update-index --assume-unchanged\n\n    # Usage: git noassume fileName\n    noassume = update-index --no-assume-unchanged\n\n    # Another alias because I cannot remember un\/no either\n    unassume = !git noassume\n\n    # List all currently git assumed files\n    assumed = \"!git ls-files -v | grep ^h | cut -c 3-\"\n<\/code><\/pre>\n
Or create the aliases from the CLI:<\/p>\n
git config --global alias.assume \"update-index --assume-unchanged\"\ngit config --global alias.noassume \"update-index --no-assume-unchanged\"\ngit config --global alias.unassume \"update-index --no-assume-unchanged\"\ngit config --global alias.assumed \"!git ls-files -v | grep ^h | cut -c 3-\"\n<\/code><\/pre>\n
One of our other projects Git-NumberedAdd<\/a> allows you to execute these commands with fabricated indexes instead of filenames.<\/p>\n
Skip Worktree<\/h1>\n
I\u2019ve always used assume unchanged but apparently --skip-worktree<\/code> would be a superior solution for changes in configuration files because it retains the S<\/code> flag (as seen with git ls-files -v<\/code>) when pulling upstream changes. I\u2019ll find out as upstream changes are a real pain with assumed unchanged.<\/p>\n
 <\/p>\n
git update-index --skip-worktree fileName\ngit update-index --no-skip-worktree fileName\n<\/code><\/pre>\n
Aliases<\/h2>\n
[alias]\n    hide = update-index --skip-worktree\n    unhide = update-index --no-skip-worktree\n    hidden = \"!git ls-files -v | grep ^S | cut -c 3-\"\n<\/code><\/pre>\n
Extras<\/h1>\n
