Summary of programming tools in Linux

Linux programming tool Summary-Linux general technology-Linux programming and kernel information, the following is a detailed description. SED and AWK

In general, sed is a more advanced data stream pattern matching and processing tool than grep, but its basic operations are for "rows" and sometimes not very convenient.

Awk can perform C-like programming and output new data streams.

Both awk and sed are used for pattern matching.

In programming, awk is generally used as a macro processor, and even awk is used as an advanced language compiler.

Awk also plays a major role in database processing. But I can't help it anymore.

Lex and yacc

In linux, it corresponds to flex and bison. VS2005 has debugging support for both scripts, which is very convenient!

Lex is used for lexical analysis, while yacc uses lex results for in-depth syntax analysis. The two must be used in combination. No overlapping functions.
