how to get cronjob running every minute

I am following advice on crontab usage online, and I ran sudo crontab -e, and my cron file is:

MAILTO=cchilder@mail.usf.edu



* * * * * /home/cchilders/scripts/python/scripts-in-progress/update_projects.py

It doesn't mail me anything, but worse, I am checking my git log for a project I made changes to, and update_projects is not running at all. When I run it by hand it works as expected. From everything I read, I really thought cronjobs were simple, and just needed a time (5 symbols) and path to a script.

I have tried testing the script calling to ensure both the python path and script path are correct. For this, I made crontest.sh:

#!/bin/bash



/usr/bin/python /home/cchilders/scripts/python/scripts-in-progress/update_projects.py

Crontest.sh works when called from terminal. I have no uploaded it in user crontab, sudo crontab, and still it isn't running.

User crontab:

* * * * * /home/cchilders/scripts/bash/crontest.sh



* * * * * /home/cchilders/scripts/python/scripts-in-progress/update_projects.py

Sudo crontab:

MAILTO=cchilder@mail.usf.edu



* * * * * /home/cchilders/scripts/bash/crontest.sh



* * * * * /home/cchilders/scripts/python/scripts-in-progress/update_projects.py

What is wrong about this, if the pathway is correct? Thank you

update_projects.py looks as follows, and is working from terminal:

#!/usr/bin/env python



import os, sys, time, subprocess

from os.path import expanduser



HOME = expanduser('~')



print 'running?





def call_sp(command, **arg_list):

    #run that

    p = subprocess.Popen(command, shell=True, **arg_list)

    p.communicate()





def get_project_path():

    i = 0

    for root, dirs, files in os.walk(HOME):

        if i >= 2:

            return os.path.join(HOME, "projects")

        i += 1

        for this_dir in dirs:

            if this_dir == "django_practice":

                return os.path.join(HOME, "django_practice")



def update_projects(home_path):

    i = 0

    for root, dirs, files in os.walk(home_path):

        for this_dir in dirs:

            if this_dir.startswith("."):

                continue

            full_path = os.path.join(root, this_dir)

            print full_path

            time.sleep(2)



            is_git_project = False

            j = 0

            for subroot, subdirs, subfiles in os.walk(full_path):

                if j >= 1:

                    break

                j += 1

                if not ".git" in subdirs:

                    break

                else:

                    is_git_project = True



            if not is_git_project:

                continue



            d = {'cwd': full_path}

            print 'git pull from {}'.format(full_path)

            call_sp('git pull', **d)

            call_sp('git commit -m "automatic update"', **d)

            call_sp('git push', **d)

        dirs[:] =

1) does your script have the executable bit set? 2) does your Python script have the Python shebang line at the start? #!/usr/bin/env python

What happens if you put the script into your user's crontab instead of root's? (crontab -e instead of sudo crontab -e)

I've had problems because the crontab execution environment isn't the same as a normal terminal, and doesn't always have the same PATH variable. Try launching a shell script that explicitly runs python with its full path (returned by which python), followed by the full path to your script. I also notice that you are referencing ~ in the script: this will be the home directory of root if you launch it using sudo, so unless this is really where your files reside you should do as @ncdownpat suggests and run it from your user's crontab.

I've had problems because the crontab execution environment isn't the same as a normal terminal, and doesn't always have the same PATH variable. Try launching a shell script that explicitly runs python with its full path (returned by which python), followed by the full path to your script. I also notice that you are referencing ~ in the script: this will be the home directory of root if you launch it using sudo, so unless this is really where your files reside you should do as @ncdownpat suggests and run it from your user's crontab.
