How to auto commit to my git repository using cron?

Question

I look into a lot of answers about this subject, but something is wrong here, let me explain. I create this script, to make my cron cleaner :)

#!/bin/bash

cd /home/valter.silva/Development/git/valter/ 
/usr/bin/git add -A 
/usr/bin/git commit -am "update `date`"
/usr/bin/git push

Then add it at my cron, valter.silva's cron, not my root cron:

00 * * * * /home/valter.silva/Development/git/valter/scripts/git/sync.sh

Restart my cron

sudo service cron restart
cron stop/waiting
cron start/running, process 6047

Aaand .. nothing happens..

But if I execute my script in command line, everything works fine. I know for a fact that sometimes if you don't put the whole path at cron scripts won't work correctly. And that I should use my cron to do that, not root's cron.

So what's wrong here ? Any ideas ? Thank you!

udpate

I follow Terdon suggestion, into log the operation, but it seems everything is okay, but not the push process though. Why ?

Solution 1

To add up, I have simplified the links, so it is more readable for someone looking for an answer based on huti's blog post.

So for your sync.sh I would add -u origin master for the push:

#!/bin/bash

cd /home/valter/git-project/
/usr/bin/git add -A 
/usr/bin/git commit -am "Daily update"
/usr/bin/git push -u origin master

Make sure you script can be executed by bash:

sudo chmod 765 ~/sync.sh

Then you can add a line to the /etc/crontab:

sudo nano /etc/crontab # To edit the file
01 18  *  *  * root  /home/valter/sync.sh

Be sure to reboot for the cron job to take effect, Now your script will be run every day at 18:01. If there is no modification, nothing will be pushed though.

Solution 2

I am not an git master, but I make some git tests on my local git test repo. When I run git push, then output is:

fatal: No configured push destination.
Either specify the URL from the command-line or configure a remote repository using

git remote add <name> <url>

and then push using the remote name

git push <name>

Q: Have you configured remote repository using git remote add command? If yes, try run git push with name of remote repository. If no, configure one, or use git push with remote repository url on command line (git push git://host.xz[:port]/path/to/repo.git/ ).

How did you add this to your user's crontab (you should use crontab -e)? What does crontab -l report? You can try to add SHELL=/bin/bash and MAILTO="valter.silva" into your user's crontab. Especially the latter might give you some error messages in your local mail (/var/spool/mail/valter.silva) if local mail system is working. And IMHO there is no need to restart the cron service.

crontab -e, not sudo crontab -e. The crontab -l is exactly that entry that I post it, there's only this entry in my cron.

Is the remote git server protected by an ssh key with a password by any chance ?

Did you ever figure it out? Arrived here by googling. Wondering if you ever fixed it.

[Valter Silva]

I'm trying to run this over a week now, trying to figure out what is happening to not commit my changes.

[Valter Silva]

Ok, terdon, will do that. I'm cloning my repo in a different computer now :)

[Valter Silva]

I update my post, could you please take a look ?

[Valter Silva]

I did configure with git remote add, I will look into it.
