1.split(string, array [, fieldsep [, seps ] ]) 功能:将string表示的字符串以fieldsep为分隔符进行分隔,并将分隔后的结果保存至array为名的数组中;数组下标为从0开始的序列; #example: netstat -ant | awk '/^tcp/{split($5,ip,":");count[ip[1]]++}END{for(i in count)print i,count[i]...
成功进入到配置界面 注:linux内核中一个功能模块有三种编译方法:一种是编入、一种去去除、一种是模块化。所谓编入就是将这个模块的代码直接编译连接到zImage中去,去除就是将这个模块不编译链接到zImage中,模块化是将这个模块仍然编译,但是不会将其链接到zImage中,会将这个模块单独链接成一个内核模块.ko文件,将来...
By default, each entry occupies one double wide entry, except if the entry is one of the following: An entry with multiple comma-separated input interfaces is split into one rule for each input interface (listed after --in-interface below). For example, this entry splits into two rules: ...
