首先需要開啟win10下的ubuntu子系統，如何開啟參考文章Windows10 安裝Ubuntu子系統

開啟Windows Powershell,輸入bash回車即可進入ubuntu子系統，輸入cat /etc/issue回車即可檢視當前Ubuntu版本號

PS C:\Users\ming> bash
[email protected]:/mnt/c/Users/ming# cat /etc/issue
Ubuntu 16.04.2 LTS \n \l

[email protected]
 
:/mnt/c/Users/ming#

預設的路徑為win10對應的C:\Users\ming資料夾

在當前資料夾下建立一個名為task的資料夾，用於儲存計劃任務的檔案

[email protected]:/mnt/c/Users/ming# mkdir task

第一種方式crontab -e建立任務：

輸入crontab -e建立任務表，進入task資料夾：

[email protected]:/mnt/c/Users/ming# cd task/
[email protected]
 
:/mnt/c/Users/ming/task# crontab -e

編輯計劃任務為* * * * * /bin/sh /mnt/c/Users/ming/task/hello.sh >> /mnt/c/Users/ming/task/hello.log，表示每分鐘執行一次task目錄下的hello.sh檔案，並將結果儲存到同文件夾下的hello.log檔案中。

# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command
* * * * * /bin/sh /mnt/c/Users/ming/task/hello.sh >> /mnt/c/Users/ming/task/hello.log
~                                                                                          ~                                                                                                                                                                                                                                                                    -- INSERT --
 

[email protected]:/mnt/c/Users/ming/task# vim hello.sh

#!/bin/sh
echo $(date '+%Y-%m-%d %H:%M:%S');
echo "Hello World"

執行cron服務啟動計劃任務

[email protected]:/mnt/c/Users/ming/task# service cron start
 * Starting periodic command scheduler cron                                         [ OK ]
[email protected]:/mnt/c/Users/ming/task#

第二種方式：檔案建立計劃任務

建立hello檔案並編輯：

[email protected]:/mnt/c/Users/ming/task# vim hello

* * * * * /bin/sh /mnt/c/Users/ming/task/hello.sh >> /mnt/c/Users/ming/task/hello.log
~                                                                                                                                                                                 ~                                                                                                                                                                                  ~                                                                                                                                                                                                                                                                      -- INSERT --

[email protected]:/mnt/c/Users/ming/task# crontab hello

{

將hello.sh的頂部加上#!/bin/sh

在執行shell命令

[email protected]:/mnt/c/Users/ming/task# sh /mnt/c/Users/ming/task/hello.sh >> /mnt/c/U
sers/ming/task/hello.log
[email protected]:/mnt/c/Users/ming/task#

}
