Learn awk, you must remember to practice, only in practice to find problems, the following on my experience in learning and practice, summed up the difference between rs,ors,fs,ofs and contact. One, RS and ors 1,rs is the record delimiter , the default delimiter is \ n, specific usage look down Copy Code code as follows: [Root@krlcgcms01 mytest]# cat test1//test file 111 222 333 444 555 666 2,rs default delimiter \ n

It's faster to understand it.Suppose a company applied for a 10 m Telecom broadband, and suddenly one afternoon, the network speed was extremely slow. Employees in the company complain constantly and strongly demand smooth network recovery. As a network manager, you need to find out the cause immediately:Different devices use different

* + Html and * html are unique tags of IE, which are not supported by firefox at the moment. * + html is also unique to IE7. Therefore, to solve the compatibility problem of padding, we need to rely on the labels mentioned above. Taking sccas-site as an example, the left-side navigation bar produces ie6, ie7, and ff browser incompatibility on padding. The modification code is as follows: # Menu7 li {Height: 25px;/* Border-right: 1px solid #666666 ;*/Text-decoration: none;Margin: 0px 0px 0px-40px
