python调用shell命令方法
缺点:不能获取返回值
要得到命令的输出内容,只需再调用下read()或readlines()等 例:a=os.popen(cmd).read()
此模块主要有如下方法:commands.getstatusoutput(cmd) 返回(status, output).commands.getoutput(cmd) 只返回输出结果commands.getstatus(file) 返回ls -ld file的执行结果字符串,调用了getoutput例: >>> 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'
