ubuntu crontab python 定时任务备记

crontab -e 写入:

# at  a.m every week with:
#   * *  tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab() and cron()
#
# m h  dom mon dow   command
  * * * notify-send 'take a break now!' 
*/30 * * * * export DISPLAY=:0.0; /bin/bash /home/jkmiao/workspace/shell/take_break.sh 
*/ * * * * /bin/bash /home/jkmiao/workspace/test/crontab_test.sh
*/ * * * * /home/jkmiao/workspace/test/crontab_test.py

注意:

# 如果已经在test.py首行加入了#!/usr/local/bin/env python，那么在crontab定时任务定义只需要：

  * * * /x/test.py

# 否则需要指定绝对路径
  * * * /usr/local/bin/python2. /x/test.py

# 同时注意, 程序中的文件路径也必须为绝对路径,否则pemission denied 错误
