I. Introduction of AWKawk: Report Generator, which is processed in behavioral units and displayed after formattingAwk is a powerful text analysis tool, with the search for grep and the editing of SED, which is especially powerful when it comes to analyzing data and generating reports. To put it simply, awk reads the file line-by-row, using spaces as the default delimiter to slice each row, and then perform various analytical processing of the cut.Second, awk variables2.1 awk built-in variables o

Explain:begin{} The most common use of this particular pattern is variable assignment. Begin this pattern is when the file does not begin to read.awk ' begin{fs= ': "; ofs="-"}{nf+=0}1", corresponding processing is 1:2:3---------> read the input delimiter into the output delimiter, but, awk has a problem, if you do not work on the field,It does not change the output delimiter, nf+=0, this assignment fart with no, NF value has not changed.

command in the form of {print}. The parameters of the print function can be variables , numeric values, or string constants. The string must be enclosed in double quotation marks. The parameters are separated by commas, and if there are no commas, all arguments are strung together. By default, a space comma is equivalent to the value in ofs .Example.
