abalone shell value

Problem Description: In the local virtual machine Linux environment, Redis is installed and operated using the shell. I have stored in Redis the value of STR is Chinese "we", but when I get the value of str under the shell get to is: \xe6\x88\x91\xe4\xbb\xac.Workaround: Just want you to start redis-cli when you add the

function allows us to divide a complex function into several modules, which makes the program structure clearer and the code reuse more efficient. Like other programming languages, the Shell supports functions as well. The Shell function must be defined before use.The Shell functions are defined in the following format:Function_name () { List of commands [r

The Shell function returns the value, generally has 3 kinds of ways: Return,argv,echo 1) Return statementThe return value of the Shell function, as in other languages, can be returned through the return statement.Example: #!/bin/bash- function mytest () { echo "arg1 = $" If [$ = 1]; then return 1 els

The Linux shell can be user-defined, and can be invoked randomly in a shell script. Here's how it's defined, and what the call needs to pay attention to. First, define the shell function (define functions) Grammar: [Function] funname [()] { Action [Return int;] } Description 1, can be defined with function fun () or directly fun (

1. When the shell script executes the Python script, you need to use the return value of the Python script to determine the command to be executed by the following program Example: There are two py programs hello.py Copy Code code as follows: def main (): Print "Hello" If __name__== ' __main__ ':Main ()world.py def main ():Print "Hello" If __name__== ' __main__ ':Main ()

AWK offers the most powerful features: Can be matched for regular expressions Style mount Flow control Mathematical operators Process Control Statements Built-in variables and functions You can think of awk as a complete programming language, and it's incredibly fast to handle text. Now a lot of shell log analysis tools can be used to accomplish this. The design is simple and the speed is very good. Related to the above six a
