Python 如何使用子流程对所有带有通配符（*）的文件进行tar

这是我想在python下运行的命令。基本上，我希望

tar

文件夹下的所有文件：

tar -jcvf doo.tar.gz /home/user/doo/*

---

返回以下错误：

tar: Removing leading `/' from member names
tar: /home/user/doo/*: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors

Traceback (most recent call last):
  File "dd.py", line 4, in <module>
    subprocess.run(['tar', '-jcvf', 'doo.tar.gz', glob.glob("*")])
  File "/usr/local/lib/python3.5/subprocess.py", line 693, in run
    with Popen(*popenargs, **kwargs) as process:
  File "/usr/local/lib/python3.5/subprocess.py", line 947, in __init__
    restore_signals, start_new_session)
  File "/usr/local/lib/python3.5/subprocess.py", line 1490, in _execute_child
    restore_signals, start_new_session, preexec_fn)
TypeError: Can't convert 'list' object to str implicitly

---

后来我用

glob

试了一下

import subprocess,  glob
subprocess.run(['tar', '-jcvf', 'doo.tar.gz', glob.glob("*")])

返回以下错误：

tar: Removing leading `/' from member names
tar: /home/user/doo/*: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors

Traceback (most recent call last):
  File "dd.py", line 4, in <module>
    subprocess.run(['tar', '-jcvf', 'doo.tar.gz', glob.glob("*")])
  File "/usr/local/lib/python3.5/subprocess.py", line 693, in run
    with Popen(*popenargs, **kwargs) as process:
  File "/usr/local/lib/python3.5/subprocess.py", line 947, in __init__
    restore_signals, start_new_session)
  File "/usr/local/lib/python3.5/subprocess.py", line 1490, in _execute_child
    restore_signals, start_new_session, preexec_fn)
TypeError: Can't convert 'list' object to str implicitly

glob

返回字符串列表。您不应该将其嵌入传递给

run

的列表中，而是将其追加

subprocess.run(['tar', '-jcvf', 'doo.tar.gz'] + glob.glob("*"))

请注意，您已经输入了主目录

subprocess.run(['tar', '-jcvf', 'doo.tar.gz'] + glob.glob("/home/user/doo/*"))

---

Shell是可以扩展的。因此，在子流程调用中指定

shell=True

，以将其展开

subprocess.run(['tar', '-jcvf', 'doo.tar.gz', '/home/user/doo/*'], shell=True)

---

我也可以这样做：

res=subprocess.check_output（['tar'，'-jcvf'，'doo.tar.gz']+glob.glob（“*”））。decode（'utf-8'）

以获得输出吗@约翰·库格曼

subprocess.run(['tar', '-jcvf', 'doo.tar.gz', '/home/user/doo/*'], shell=True)
