LINUX基础报错汇总

1. SyntaxError: invalid syntax

使用命令提示：

[root@localhost ~]# dstat
  File "/usr/bin/dstat", line 120
    except getopt.error, exc:
                       ^
SyntaxError: invalid syntax

原因：python版本问题，dstat只支持python2
解决：修改python版本

[root@localhost]# vi /usr/bin/dstat
#!/usr/bin/python2.7

[root@localhost ~]# dstat
You did not select any stats, using -cdngy by default.

2. missing operand

# stat -t
stat: missing operand
Try 'stat --help' for more information.

原因：缺少命令使用时需要带上操作数,
stat '文件'

# stat /data/
  File: ‘/data/’
