How can I shorten the command for making a Git commit with author specified, without setting global configuration? -

i working on scripts on shared server, , need commit progress git repository periodically. since server , user logged in both shared, don't want set global user names , e-mails, common solution not entering commit author every time. if don't specify author, git assume name name based on shared system's user , host names, commits won't associated me. have been making commits following command address this:

git commit -m "commit message" --author="firstname lastname "

how can shorten command don't have type out author every time, without setting global configuration options?

here @ least 2 options address this:

set repository-specific options

have each user uses machine make own clone of repository. then, each user can set local user name , e-mail configuration option in copy of repository:

git config user.name "firstname lastname"
git config user.email "email@domain.com"

simply leaving off --global option create [user] section in repository's .git/config file, when user makes commit in repository, user name , e-mail attached commit.

create alias command

you can set alias committing includes author:

git config --global alias.commitauthorname 'commit --author="firstname lastname " -m'

then commit using command:

git commitauthorname "commit message"

you can leave -m out of alias if don't want use option every time.

note: approach cause git generate following message each commit used with:

your name , email address configured automatically based on username , hostname. please check accurate.

also, each commit made alias have author set accurately, committer metadata attached commit still based on username , hostname git found.
