The normal os.popen(cmd, mode) call spawns a shell command and provides a file interface to just the input or output of the process depending on whether mode is 'r' or 'w'. This module provides the functions popen2(cmd) and popen3(cmd) which return two or three pipes to the spawned command.

On UNIX, 'cmd' may be a sequence, in which case arguments will be passed directly to the program without shell intervention (as with os.spawnv()). If 'cmd' is a string it will be passed to the shell (as with os.system()). The 'capturestderr' flag, if true, specifies that the object should capture standard error output of the child process. The default is false. If the 'bufsize' parameter is specified, it specifies the size of the I/O buffers to/from the child process.i i i t wt rN( R t ost pipet p2creadt p2cwritet c2preadt c2pwritet capturestderrt erroutt errint forkt selft pidt dup2t _run_childt cmdt closet fdopent bufsizet tochildt fromchildt childerrt NoneR t append( R R R R R R R R R R ( ( R t __init__ s, c C s‘ t | t ƒ o d d | g } n x> t d t ƒ D]- } y t i | ƒ Wq3 t j o q3 Xq3 Wz t i | d | ƒ Wd t i d ƒ Xd S( Ns /bin/shs -ci i i ( t isinstanceR t basestringt ranget MAXFDt iR R t OSErrort execvpt _exit( R R R( ( ( R R A s c C s€ | i d j oi yL t i | i t i ƒ \ } } | | i j o | | _ t i | ƒ n Wqy t i j o qy Xn | i S( sh Return the exit status of the child process if it has finished, or -1 if it hasn't finished yet.i N( R t stsR t waitpidR t WNOHANGR t removet error( R R R, ( ( R R N s c C s` | i d j oI t i | i d ƒ \ } } | | i j o | | _ t i | ƒ qY n | i S( s9 Wait for and return the exit status of the child process.i N( R R, R R- R R R/ ( R R R, ( ( R t wait[ s ( t __name__t __module__t __doc__R, t FalseR# R R R1 ( ( ( R R s " t Popen4c B s t Z d Z d d „ Z RS( Niÿÿÿÿc C sæ t ƒ t i ƒ \ } } t i ƒ \ } } t i ƒ | _ | i d j oA t i | d ƒ t i | d ƒ t i | d ƒ | i | ƒ n t i | ƒ t i | d | ƒ | _ t i | ƒ t i | d | ƒ | _ t i | ƒ d S( Ni i i R R ( R R R R R R R R R R R R R R R R R R R R" ( R R R R R R R ( ( R R# h s ( R2 R3 R!
