What is a shell script?Shell script is similar to batch processing under Windows/dos, that is, the use of various commands pre-placed into a file, convenient one-time execution of a program file, mainly for the convenience of administrator settings or management. However, it is more powerful than batch processing under Windows and is more efficient than editing programs with other programming programs, and it uses commands under Linux/unix.Initial knowledge of shell scriptsAfter you write a list

file compiled generated by the class file, found the results of the same as in the Java file. Then look at the charset specified in the JSP as iso-8859-1. String a= "Chinese";Out.println (a);%> Similarly, the file is written in UltraEdit, "Chinese" is also stored as GB2312 encoding "D6 D0 CE C4". First simulate the process of generating Java files and class files: JSPC uses iso-8859-1 to interpret "Chinese" and maps it to Unicode. Since Iso-8859-1 is a 8-bit, and is a Latin language, its mappin
