Question

我是Ubuntu和编程的新手。我正在测试我在github上找到的程序，下载并将OSM数据导入postgis。当我从终端运行它时（url和名称是假的）：

make all NAME=dbname URL='http://myurl'

使用postgres用户。

现在我需要每天运行此命令。所以我写了那个剧本：

#!/bin/bash
# go to the directory with Makefile
cd /PCuserhome/directory/to/Makefile/
# run Makefile
make all NAME=dbname URL='http://myurl'

当我从终端运行它时它会起作用。

所以我以这种方式将它添加到crontab（postgres用户）：

0,15,30,45 * * * * /PCuserhome/myscript.sh

它创建数据库，但可能无法运行渗透选择（渗透在所有用户的路径中）。有什么想法解决这个问题？谢谢！

Answer 1

crontab命令仅在最小环境变量下执行，即

$PATH（无论如何都是debian），

因此，如果您依赖$PATH中的程序，它将会失败。考虑指定渗透程序的绝对路径，无论它在何处被调用。

或者，您可以在脚本中更改export PATH="/my/bin:$PATH"本身

* * * * * env > /tmp/env.txt

p.s。：您可以通过添加简单的cron作业来检查环境
