通过 python 执行 bash 脚本出现语法错误

通过 python 执行 bash 脚本出现语法错误

因此，我尝试通过 Python 获取文件。代码如下：

import os
source = 'source /home/software/cadence/release2013/setup/xyz.setup p'
os.system(source)

由此得出以下结论：

/home/software/cadence/release2013/setup/xyz.setup: line 23: syntax error near unexpected token `$HT'
/home/software/cadence/release2013/setup/xyz.setup: line 23: `switch ($HT)'

现在，我向你保证。xyz.setup 没有任何问题。它已经被无数次地引用，并且被许多人引用过。此外，当我直接通过终端引用它时

source /home/software/cadence/release2013/setup/xyz.setup p
 Program Research license set

它工作得很好！我很困惑。有人能帮忙吗？如果不行，还有其他方法吗？我试过了subprocess.call，但是参数无法传递给文件。

这是 xyz.setup，尽管其中肯定没有错误。

您的脚本语法正确csh，但os.system调用默认 shell /bin/sh。如果您希望脚本被正确解释，请使用

subprocess.call(['/bin/csh','-c','source /home/software/cadence/release2013/setup/xyz.setup'])
