问题描述
我想知道 subprocess.call("if [ ! -d '{output}' ]; then mkdir -p {output}; fi",shell=True)
是否会被解释sh
或 zsh
而不是 bash
在不同的服务器?
有人对此有想法吗?
我应该怎么做才能确保它被 bash
解释?

<块引用>在 shell=True 的 Unix 上,shell 默认为/bin/sh
请注意,/bin/sh 通常与不同的符号链接,例如在 ubuntu 上:
$ ls -la/bin/shlrwxrwxrwx 1 root root 4 Mar 29 2012/bin/sh ->短跑
您可以使用 executable
参数替换默认值:
... 如果 shell=True,打开Unix 的可执行参数为默认/bin/sh.
subprocess.call("if [ ! -d '{output}' ]; then mkdir -p {output}; fi",壳=真,可执行文件="/bin/bash")
I was wondering whether subprocess.call("if [ ! -d '{output}' ]; then mkdir -p {output}; fi",shell=True)
will be interpreted by sh
orzsh
instead of bash
in different server?
Anyone has ideas about this?
What should I do to make sure that it's interpreted by bash
?

On Unix with shell=True, the shell defaults to /bin/sh
Note that /bin/sh is often symlinked to something different, e.g. on ubuntu:
$ ls -la /bin/sh
lrwxrwxrwx 1 root root 4 Mar 29 2012 /bin/sh -> dash
You can use the executable
argument to replace the default:
... If shell=True, on Unix the executable argument specifies a replacement shell for the default /bin/sh.
subprocess.call("if [ ! -d '{output}' ]; then mkdir -p {output}; fi",
shell=True,
executable="/bin/bash")
