/bin/sh: 1: /home/samitha/bash.sh: Permission denied

回答1:
you can try the following solution as well:
chmod +x post.php
chmod +x bash.sh
echo "* * * * * /home/samitha/bash.sh >> /home/samitha/log/cron.log 2>&1" >> cronjob
chmod +x cronjob
/etc/init.d/crond start #redhat based servers like centos
/etc/init.d/cron start #debian based servers like ubuntu
crontab cronjob
回答2:
The user executing that cron (the one who executes cron -e) doesn't have proper rights for executing that script. That is: either the script lacks the execution flag, or it's not possible to reach it because some of its ancestor directories lack the execution flag.

The problem could be that your user does not have the rights to execute the file.
First you set the execution flag for your script
chmod +x /home/samitha/bash.sh
Then you should check the permissions for the php file with
ls -lah /var/www/Controller
If neither your usergroup nor your username shows up, you have to run the script with superuser rights or change its permissions.
First way would be put your entry in
sudo crontab -e
or the second one would be (which I would not recommend, as everyone would be allowed to execute the script by calling your site)
chmod a+x /var/www/Controller/post.php
回答4:
- File must be executable (@see chmod)
- All parent directories must have the execution flag (@see chmod)
- If crontab is running by different user i.e. not owner, maybe this user don't have rights to execute. (@see chown)
