The commands module contains wrapper functions for os.popen() which take a system command as a string and return any output generated by the command and, optionally, the exit status.
The commands module defines the following functions:
Return the output of ls -ld file as a string. This function uses the getoutput() function, and properly escapes backslashes and dollar signs in the argument.
Deprecated since version 2.6: This function is nonobvious and useless. The name is also misleading in the presence of getstatusoutput().
