I would like to set up a scheduled task via anacron but I would like to do so in user mode. How can I achieve this?

You can set up a separate anacron instance to run in user mode:

  1. Create a .anacron folder in your home directory and in it two subfolders, etc and spool:

    mkdir -p ~/.anacron/{etc,spool}
  2. Create a new file ~/.anacron/etc/anacrontab with contents similar to the following:

    # /etc/anacrontab: configuration file for anacron
    # See anacron(8) and anacrontab(5) for details.
    # period  delay  job-identifier  command
    1         10     testjob         test.sh
  3. Add the following line to your crontab using crontab -e:

    @hourly /usr/sbin/anacron -s -t $HOME/.anacron/etc/anacrontab -S $HOME/.anacron/spool

    I think you need to run anacron periodically; it seems to run once then quit. The system's anacron is called once every hour. I suppose a similar strategy would work here, i.e. call the user anacron from the user crontab.

    @Sparhawk agreed, in particular Ubuntu 15.10 anacron uses both /etc/apm/event.d/anacron and /etc/init/anacron.conf to take care of restarts. Dec 9, 2015 at 21:53

    You need to run anacron hourly with a cron job, e.g. 01 * * * * /usr/sbin/anacron -t /home/user/.anacron/etc/anacrontab -S /home/user/.anacron/spool Aug 17, 2016 at 5:15

    This won't work if the user has an encrypted home directory. I've replaced that last crontab -e command with an entry in my ~/.profile instead.

    @Glutanimate thank you for this! It has been driving me crazy for a long time.

This worked for me (thanks), but I didn't use the last step given in the answer:

Then add the following line to your ~/.profile:

I'm using Ubuntu Studio 12.10 Quantal and in my case instead of that last step I put that one liner here: “Applications Menu” → “Settings” → “Settings Manager” then in the Settings Manager under “Session and Startup” then the “Application Autostart” tab.

This is for those of us that are GUI users, because ~/.profile is only sourced by bash when it starts a log-in interactive shell (even ~/bashrc is not so useful since that is only sourced when bash is starting an interactive shell).

  • Mmh, I am a GUI user myself and the line in .profile has always worked fine for me (Ubuntu 12.04 here). Sep 12, 2013 at 14:33

The anacrontab shown above has a problem: anacron looks for executables only in the directories specified in PATH. So it will not find test.sh.

A better solution is to use the command run-parts:

# /etc/anacrontab: configuration file for anacron

# See anacron(8) and anacrontab(5) for details.


# period  delay  job-identifier  command
1         10     dailyjob        run-parts ${HOME}/.anacron/daily/

This requires that we create the directory daily:

mkdir -p ~/.anacron/{etc,spool,daily}

run-parts will not execute scripts with '.' in the name, such as "test.sh", so rename the script to, for example, "my-test".

There is yet another wrinkle: If the computer does not run 24/7, then one does not have control over at what time the daily script is run. I have a web scraping script that I want to be run at about 11 am, or later during the day. I fix this problem by scheduling the web scraping job in the "at" facility (sudo apt install at).

So I have a script daily/crawl which looks as follows:


current_time_as_number=$(date +%H%M)
if [ "${current_time_as_number}" -ge "${preferred_time_as_number}" ]; then
at -M -f "${HOME}/bin/crawl-dagpris.sh" "${scheduled_time}"
