最近有个需求就是页面上执行shell命令,第一想到的就是os.system,
os.system('cat /proc/cpuinfo')
尝试第二种方案 os.popen()
output = os.popen('cat /proc/cpuinfo') print output.read()
尝试第三种方案 commands.getstatusoutput() 一个方法就可以获得到返回值和输出,非常好用。
(status, output) = commands.getstatusoutput('cat /proc/cpuinfo') print status, output
>>> 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') '-rwxr-xr-x 1 root 13352 Oct 14 1994 /bin/ls'
