git commit can't find (global) config running in cron job

Question

I want to commit some file changes using a cron job calling a script with the following line in roots crontab

0 * * * * cd /files/ && ./backup.sh >/tmp/cronlog 2>/tmp/cronerror

the script looks as follows:

#!/usr/bin/env bash

… prepare the files for the backup …

echo "commit changes …"
git add -u
git commit -m "backup"
git push

Prior to the cron setup I've also set user.email and user.name for the root user and I've checked that the script runs if I call if from the command line.

But in /tmp/cronerror I receive the following well known message.

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
…

I've also tried setting HOME=/root in the script but this doesn't seam to make a difference.

Is there a way of telling the git command where to find the global git-config when running in a cron job?

我的解决方案是使用git config …不带--global选项，它将配置存储在当前存储库中，git可以在其​​中找到它。
