测试：
# ls -l /opt/oracle/tomcat/ |awk '/^d/{ print $NF}'
tomcatServer229-1
tomcatServer229-2
# echo tomcatServer229-1|awk '{print length($1)}'
17
# a=(" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" "" ")
# echo "tomcatServer229-1${a:17}|Alive | pid"
tomcatServer229-1 |Alive | pid
#
标绿的地方就是对空格的处理，实际上实例的长度不能够大于a中规定的字符的长度，如果超过了会怎么样呢？
Processes in Instance: SOR_SYS.99bill.com
-----------------------------+------------+-----------
instance |status | pid
-----------------------------+------------+-----------
tomcatServer229-1 |Down | N/A
tomcatServer229-2 |Down | N/A
tomcat-tomcat-tomcat-tomcat-tomcat-tomcat|Down | N/A 标绿的地方在哪里？转帖也有点职业精神嘛
