set list的使用

Q:检查nagios一直报错
[root@localhost objects]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Processing object config file '/usr/local/nagios/etc/objects/hosts.cfg'...
Error: Invalid host object directive '} '.
Error: Could not add object property in file '/usr/local/nagios/etc/objects/hosts.cfg' on line 6.
Error processing object config files!

Solution:
检查配置文件
/usr/local/nagios/etc/objects/hosts.cfg

完全看不出头绪嘛

说第6行{   附近有问题
用set list 查看

我也是醉了，大括号后面有一个空格
删掉就好了

[root@localhost objects]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

[root@localhost objects]# service nagios restartRunning configuration check...done.
Stopping nagios: done.
Starting nagios: done.

总结：set list的使用

用处：检查不可见的特殊字符，把它显示出来，如我这里的空格

^M  window的文件符号

^I  制表符
