shell - How to keep a folder up-to-date with a git repo? -

this shell script periodically check github latest code, , download, compile, , run if there difference between have locally , pulled.

i know can clone new directory, , check changes, , go there, seems incredibly wasteful, git should have logic checking differences between files , updating those.

to complicate matter, "local" version may @ point "latest" version, , in case want discard "new" changes , pull "stable" repository

i have this:

status=`cd $gitdir && git pull` if [ "$status" != "already up-to-date." ]; cd $gitdir && git fetch origin cd $gitdir && git reset --hard origin/master

but fails when "local" "newer" - suggestions?

update: have looked clean option, gets rid of files excluded in .gitignore - want solution leave alone, discards changes source files , pulls latest github.

update #2: think need:

git fetch --all git reset --hard origin/master

but need testing, confirmation looking nice

update #3: seems either

git reset --hard origin/master git reset --hard head

works far overwriting local files, how know when 2 different (looking git diff.. )

first, since git 1.8.5 (nov 2013), you can utilize -c alternative git, in "git --git-dir not working expected".

status=`git -c $gitdir pull` if [ "$status" != "already up-to-date." ]; git -c $gitdir fetch origin git -c $gitdir reset --hard origin/master

second, hear on client json payload coming github webhook triggered on push github repo. way, wouldn't have execute script unless needed.
