我想用anacron在Ubuntu13.04上每周做一次工作。
这是我的/etc/crontab:
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
# m h dom mon dow user command
17 * * * * root cd / && run-parts --report /etc/cron.hourly
25 6 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6 * * 5 root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6 1 * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
#这是我的/etc/anacrontab:
# /etc/anacrontab: configuration file for anacron
# See anacron(8) and anacrontab(5) for details.
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
HOME=/root
LOGNAME=root
# These replace cron's entries
1 5 cron.daily run-parts --report /etc/cron.daily
7 10 cron.weekly run-parts --report /etc/cron.weekly
@monthly 15 cron.monthly run-parts --report /etc/cron.monthly这是我的/etc/cron.Week/0 0anacron:
#!/bin/sh
#
# anacron's cron script
#
# This script updates anacron time stamps. It is called through run-parts
# either by anacron itself or by cron.
#
# The script is called "0anacron" to assure that it will be executed
# _before_ all other scripts.
test -x /usr/sbin/anacron || exit 0
anacron -u cron.weekly最后,这里是我输入的脚本/etc/cron.Week/:
#!/bin/sh
curlftpfs -o allow_other,skip_pasv_ip mauro-casa.no-ip.org:21001/Volume_1/Foto/Marta/ /home/mauro/Pubblici/Marta_NAS/
sleep 5
rsync -rlt --update --ignore-existing --size-only --exclude=.picasaoriginals/* --exclude=.picasaoriginals --exclude=.directory --exclude=.dropbox --exclude=picasa.ini --temp-dir=/home/mauro/.rsync-temp/ /home/mauro/Dropbox/Marta/ /home/mauro/Pubblici/Marta_NAS/
umount -l /home/mauro/Pubblici/Marta_NAS/这个脚本显然是chmoded +x,如果手动执行它(使用sudo),它工作得很好。
按照要求,这里的输出
cat /var/log/cron.log | grep "Oct 13"

您没有发布要运行的脚本的实际名称,但是它很可能包含一个点('.'),就像它以‘..sh’结尾一样。
run -部件将不运行除了字母、数字字符或连字符以外的其他任何内容的脚本。去掉点,你就没事了。

通常,anacron不作为守护进程运行。在基于Debian的系统上,它与/etc/cron.d/anacron的经典cron一起运行。它也在系统启动后开始,从睡眠中恢复并改变电源管理状态。
您可以检查最后一次使用sudo cat /var/spool/anacron/cron.weekly运行anacron作业的日期。

cat /etc/cron.d/anacron将告诉您anachron将运行的时间和时间,例如:
# /etc/cron.d/anacron: crontab entries for the anacron package
SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
30 7 * * * root start -q anacron || :向你展示它每天早上7:30运行,但每周只运行一次。它检查写入的日期。
sudo cat /var/spool/anacron/cron.weekly(如果日期较旧,它将启动并更新该文件中的日期)
