I have a repository for storing all my configs (e. g. .ssh/config). From time to time I need a backup them, so I need to run these commands 

git commit -am 'Auto git backup `date -I`'
git push origin master

It is pretty annoying so I decided to make a cron job, which runs simple script with these lines above. I ran crontab -e and added new line at the end of file. I also replaced git with which git inside of script. git commit command works perfectly in contrast with git push. When I made some debug prints I got

ssh: Could not resolve hostname bitbucket.org: Name or service not known
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.

But when I run script manually, it works. I think it is because of SSH aliases in my .ssh/config, which looks like 

Host     bitbucket.org-personal
HostName bitbucket.org
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa

Host    bitbucket.org-work
HostName bitbucket.org
PreferredAuthentications publickey
IdentityFile ~/.ssh/another_id_rsa

Does somebody have idea, how to propagate SSH aliases to environment, which runs cron jobs? Also maybe I am wrong and problem is caused by something else.

    You miss how the line you wrote into the crontab look like. Are you sure the backup is run when the network is up? – Jakuje Aug 13 '17 at 20:37
  • Line in crontab is `@reboot /home/user/scripts/backup-and-commit.sh` and I added some debug messages and I'm sure cron job works as I want. Do you think it doesn't push commits because of network issues? – 32cupo Aug 14 '17 at 06:17

    Yes. The error is obvious that you do not have network. Try to postpone the run some minutes to wait for the network. – Jakuje Aug 14 '17 at 06:23

The issue was a network connection. When I added sleep (or modified solution from here How to check internet access using bash script in linux?) at the begging of the script, it works perfectly.
