python执行系统命令
os.system('cat /proc/cpuinfo')output = os.popen('cat /proc/cpuinfo')
print output.read()(status, output) = commands.getstatusoutput('cat /proc/cpuinfo')
print status, output
Python Document 中给的一个例子,很清楚的给出了各方法的返回。>>> import commands
>>> commands.getstatusoutput('ls /bin/ls')
(0, '/bin/ls')
>>> commands.getstatusoutput('cat /bin/junk')
(256, 'cat: /bin/junk: No such file or directory')
>>> commands.getstatusoutput('/bin/junk')
(256, 'sh: /bin/junk: not found')
>>> commands.getoutput('ls /bin/ls')
'/bin/ls'
>>> commands.getstatus('/bin/ls')
