Setting up & Operating GIT repositories

Client Setup

identify yourself,

#git config --global --edit
git config user.name
git config user.name "your name or user@hostname"
git config user.email
git config user.email "your@email"

some defaults,

#git config --global push.default simple
#git config --global core.editor elvis

Basic usage

see the changed files

git log
git show COMMIT --stat
git show COMMIT

see the 5 last commit diffs

git log --patch -5

see what’s been staged for commit already

git diff --cached --stat
git diff --cached
git status -v

Dirty speed-up tweaks

for text or html files, eventually avoid comments

git config --global alias.nc 'commit -a --allow-empty-message -m ""'
git config --global alias.ci 'commit --allow-empty-message -m ""'
git config --get-regexp alias

–or– directly use the shell aliases for that matter

alias push='git commit -a --allow-empty-message -m "" && git push'
alias commit='git commit --allow-empty-message -m ""'
alias stat='git diff --stat --cached origin/master'

Fetching a repository

Github

git clone git@github.com:ACCOUNT/REPO.git
#git clone https://github.com/pbraun9/slackbuilds.git

Gitlab on-premises

git clone ssh://git@gitsrv/home/git/project.git
#git clone http://git@gitsrv/home/git/project.git
#git clone https://git@gitsrv/home/git/project.git

GIT in production

update the list of branches and switch to the new revision

    git fetch -a
    git checkout release-1.1.0
    git pull

and restart the application

Troubleshooting

CAs

Don’t forget to define your trust store, you need to do that manually on NetBSD

git config --global http.sslVerify true

Enabling RAW control chars

If you got shit like this when doing git diff,

ESC[32m+ESC[mESC[32m#

==> enable “raw” control characters in your PAGER,

git config --global core.pager "less -r"

Sharing a repo across the file-system

If you need to share a repo with another user, using group permissions as such

#homedir does not need to be writable, but executable
chmod 750 /home/gollum/
cd /home/gollum/

#now making the repo writable for the group
chown -R gollum:gollum pub.git/
find pub.git/ -type d -exec chmod 770 {} \;
find pub.git/ -type f -exec chmod 660 {} \;
find pub.git/ ! -type d ! -type f

you need to fsck/prune/repack/fsck after changing perms. The link (see below) even says you need to do it on both sides, local and remote.
