制作 bash 文件以显示到终端

Question

我遇到了获取问题

source ./venv/bin/activate
python3 run.py > console.log.txt 2>&1 & tail -f console.log.txt
deactivate

当我将它放入 .sh 并尝试 bash 运行它时，在终端上显示任何内容。当我直接在终端中运行该命令时它可以工作。无论如何我可以解决这个问题吗？

运行 bash -x startup.sh 显示：

+ source ./venv/bin/activate
++ '[' ./venv/bin/activate = start.sh ']'
++ deactivate nondestructive
++ unset -f pydoc
++ '[' -z '' ']'
++ '[' -z '' ']'

Answer 1

试试这个：

 #!/bin/bash

pwd
echo
cd ~/<your_folder_where_venv_folder_is_present>; source venvPython375/bin/activate
echo "-- Inside Virtual ENV dir: `pwd`"
python3 run.py > console.log.111.txt 2>&1 &  timeout 5 tail -f  console.log.111.txt
echo "-- Deactivating from Venv"
deactivate
echo

由于您没有告诉tail 何时停止，它会一直等待您的用户输入并且永远不会返回。使用timeout 5 或任何号码都会有所帮助。

我的例子 run.py 是：

#!/bin/python

import os
for k, v in os.environ.items():
    print(f'{k}={v}')
