6.8.3 Replacing Older Functions with the subprocess Module

In this section, "a ==> b" means that b can be used as a replacement for a.

Note: All functions in this section fail (more or less) silently if the executed program cannot be found; this module raises an OSError exception.

In the following examples, we assume that the subprocess module is imported with "from subprocess import *".

• 6.8.3.1 Replacing /bin/sh shell backquote
• 6.8.3.2 Replacing shell pipe line
• 6.8.3.3 Replacing os.system()
• 6.8.3.4 Replacing os.spawn*
• 6.8.3.5 Replacing os.popen*
• 6.8.3.6 Replacing popen2.*
