awk accepts data from stdin by default, printing text to stdout.Default input and output delimiters for awk:FS: Enter field delimiter, default space.RS: Enter line delimiter, default \ n.OFS: Output field delimiter, default space.ORS: Output line delimiter, default \ n.Example: Make multiple rows into a row by changing the default built-in variableFile.txt (the number of information bars for each person is not sure, the distinction is a blank line)Pedestrian ArmorTel: 13777707771Mobile: 010-1234

The installer only needs to re-create the binary resource of the setup program and write it back to the disk. decompress the package and start it with a new process. It is not difficult to save and read/write binary resources-the processing details and code have been described earlier in this article.Since Windows 95, each Windows platform has a

pointer to the structure of a file type BIO_METHOD. Its function implementation is as follows: BIO_METHOD * BIO_s_file (void) { Return ( methods_filep ); } In fact, from this structure, we can see the first class of BIO implementation, that is, all BIO actions are based on its BIO _ METHOD (the first parameter) to determine its action and behavior, so as to realize BIO polymorphism for various types . In the file type, use BIO_read and BIO_write described earlier to read the underlying file dat

A Basic introduction1.awk:Awk is a powerful text analysis tool that is irreplaceable in the processing of text files and generating reports. Awk considers text files to be structured, which defines each input row as a single record, each string in the row is defined as a field (segment), and the domain and domain are split using a delimiter.2. Functions: Flow control, mathematical operations, Process Control, built-in variables and functions, loops and judgments3. Working principle:Awk makes eac
