如何强制/斌/ bash的跨$ P $的oneliners PTER [英] How to force /bin/bash interpreter for oneliners

问题描述

我有一个与Python使用os.system执行的单行bash命令（）

I have a one liner bash command that is executed with python os.system()

for FILENAME in mydir/PRE_*; do echo $FILENAME `printf ${FILENAME:0:12}; printf ${FILENAME:23}`; done;

它通过循环目录中的所有文件和重命名它们，采取字符12-23出了名的。当我和我的服务器登录执行它通过庆​​典，但是当我与Web用户执行它通过蟒蛇它抛出错误的命令工作正常。

It loops through all files in a directory and renames them, to take chars 12-23 out of the filename. The command works fine when I execute it through bash with my server login, but when I executed it through python with the web user it throws errors.

我发现，这是因为网络用户的默认shell是/ bin / sh的，而不是/斌/ bash的。

I found out that this is because the web user's default shell is /bin/sh instead of /bin/bash.

我能够与该用户登录并更改外壳为/ bin / bash的。

I am able to log in with that user and change the shell to /bin/bash.

所以，问题是我可以强制单行不改变默认的shell为用户提供/斌/ bash的执行？

So the question is can I force the one-liner to execute with /bin/bash without changing the default shell for the user?

推荐答案

也许你可以称呼其为：

/bin/bash -c '$cmd'

其中， CMD $ 是完整的命令行。
