There are two ways in which a Perl program needs to handle user input parameters:The first method is to use the @argv arrayThe second approach is to call the Getopt::long module, which is convenient and powerful. This article mainly introduces this method.Getopt::long invocation instance in Perl:#!/usr/bin/perluse getopt::long;my ($verbose, $monitor, $debug, $test);My @libs = ();My%flags = ();' monitor! ' ' Debug:i ' ' Test|t=s ' ' Lib=s ' ' Flag=s ' );Print "verbose= $verbose

First look at the effect: In Linux terminal, ANSI escape sequence to control colorBasic rule: Precede with \033[, end with \033[0m reset to original colorYou can enter the following sentence in the terminal, you can see the output of the green hello. >>echo-e ' \033[0;32mhello\033[0m ' where 0;32m controls the color.The simplest, as long as the 0;32m in the 2 change to 0-7, it corresponds to different colors. Using this, in Python, you can do this

write a relative path, it is relative to the current working directory's path, not the path relative to List.txt.The file list can be either a single file path or a directory path. Note the relative path and absolute path are distinguished, and the rules are the same as described earlier.In addition to containing the specified directory/file, you can also exclude the specified directory/file.G:\>7z.exe a g:\temp. zip g:\temp\ [email protected]:\temp\list.txt-X indicates that the files and direc
