為什麼 anacron 不執行計劃的任務？

我已經設置anacron執行幾個任務，但由於某種奇怪的權限錯誤，它似乎失敗了。

這是我的anacrontab：

# /etc/anacrontab: configuration file for anacron

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

SHELL=/bin/sh
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
# the maximal random delay added to the base delay of the jobs
RANDOM_DELAY=45
# the jobs will be started during the following hours only
START_HOURS_RANGE=3-22

#period in days   delay in minutes   job-identifier   command
1   5   cron.daily      nice run-parts /etc/cron.daily
7   25  cron.weekly     nice run-parts /etc/cron.weekly
@monthly 45 cron.monthly        nice run-parts /etc/cron.monthly

@daily  1   bashrc.daily    rsync -aAX $HOME/.bashrc /run/media/MYUSER/samsung/home/MYUSER/.bashrc
@daily  1   bash_aliases.daily  rsync -aAX $HOME/.bash_aliases /run/media/MYUSER/samsung/home/MYUSER/.bash_aliases
@daily  5   variety.daily   rsync -aAX $HOME/.config/variety/ /run/media/MYUSER/samsung/home/MYUSER/.config/variety/
@daily  3   testfile.daily  rsync -aAX $HOME/Documents/flag.hs /run/media/MYUSER/samsung/flag.hs
@weekly 5   st_apps.daily   rsync -aAX $HOME/.local/share/Steam/steamapps/ /run/media/MYUSER/samsung/home/MYUSER/.local/share/Steam/steamapps/
@weekly 15  st_ud.daily rsync -aAX $HOME/.local/share/Steam/userdata/ /run/media/MYUSER/samsung/home/MYUSER/.local/share/Steam/userdata/
@weekly 1   anacrontab.weekly   rsync -aAX /etc/anacrontab /run/media/MYUSER/samsung/home/anacrontab

這是的輸出journalctl -b --no-pager --catalog | grep anacron

jan. 14 00:02:09 MYPC anacron[73073]: Anacron started on 2022-01-14
jan. 14 00:02:09 MYPC anacron[73073]: Can't open timestamp file for job cron.daily: Permission denied
jan. 14 00:02:09 MYPC anacron[73073]: Aborted

jan. 14 00:02:50 MYPC sudo[73124]:     MYUSER : TTY=pts/0 ; PWD=/home/MYUSER ; USER=root ; COMMAND=/usr/bin/dd bs=4k of=/etc/anacrontab

有人可以在正確的方向上刺激我嗎？

我anacron之前工作過，但不再工作了，所以我決定採取不同的方法。為了能夠在沒有升級權限的情況下執行它，您需要執行以下操作：

1. .anacron使用命令在您的主目錄和兩個子目錄（etc和spool）中創建一個文件夾mkdir -p ~/.anacron/{etc,spool}。
2. etc通過執行與touch $HOME/.anacron/etc/anacrontab原始/etc/anacrontab. 例如：

# Personal anacrontab

SHELL=/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

#period in days   delay in minutes   job-identifier   command
@daily  1   bashrc.daily    rsync -aAXr $HOME/.bashrc /run/media/myuser/samsung/home/myuser/.bashrc
@daily  1   bash_aliases.daily  rsync -aAXr $HOME/.bash_aliases /run/media/myuser/samsung/home/myuser/.bash_aliases

3. 在終端中，輸入crontab -e並添加以下內容：

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

您可以測試等待 cron 執行每小時任務，也可以anacron通過 running 強制立即執行anacron -fnd -t $HOME/.anacron/etc/anacrontab -S $HOME/.anacron/spool/。

希望這對將來的其他人有所幫助！
