Golang has os package that is used for deleting a file. In this os package the filename that we wish to delete is initially specified. The file is then deleted using the os.Remove method from the os package.In this article we are using two example to demonstrate the process of deleting a file. Syntax os.Remove() The os.Remove function in Go is used to delete a file or directory identified by a file path. The file or directory path that you want to remove is the only argument for this function. Algorithm Step 1 − Create a package main ... Read More
In Golang, we can use Os Packages and IO packages to copy data from one file to another file. n the first method, we'll use OS packages like os.open, os.create and os.copy function. Whereas in the second method, we will use ioutill.Readfile and ioutil.Writefile to copy the files. Method1: Using OS Package In this illustration, the program initially uses the os.Open function to open the source file, source.txt. Then it uses the os.Generate function to create the destination file, destinaton.txt. Then, io.Copy function is used to copy the contents of the source file to the target file. Syntax os.Open ...

Both Testing and Debugging are important steps during and after the development of any software or application developed in any programming language. On the basis of their features and methods of practice, we can distinguish between Testing and Debugging. Read this article to learn more about Testing and Debugging and how they are different from each other. What is Testing? Testing is a process to check if a software application is working properly or not. The primary goal of testing is to find the errors and bugs in an application. The person who performs the testing is known as ... Read More
Rename() is one of the internal function of golang used for renaming a specific file. Here we have used three examples in the first one we are using the Rename() function present in os package while in the second example we are using TempFile() function present in the ioutil package respectively. Method 1: Using OS Package In this method, we will write a go language program to rename a specified file by another name by using the Rename() function present in os package. Syntax func Rename(oldpath, newpath string) error The Rename() function is present in os package and ... Read More
In golang, we have internal function like stat(), Open(0 and Readfile() that is used for checking whether a specific file exist or not. In the first example we are using the stat() method present in the os package while in the second and third example we are using Open() and ReadFile() function respectively. Method 1: Using STAT() Method In this method, we will use the Stat function present in os package to check if the file exists or not. Syntax Stat(file string) The stat() function is present in os package and is used to get the status of ... Read More
System testing is a type of software testing in which a software product is tested as a whole for the validation of its functional and non-functional requirements, whereas integration testing is a testing in which a software product is tested for the interfacing between its different modules that are interlinked with each other. Read this article to learn more about system testing and integration testing and how they are different from each other. What is System Testing? System Testing is a testing which is used to validate the functionality of a software product developed. It is also known as black ... Read More
In Golang, we can use openfile() and Stat() function to check whehter a file has writable permission or not. Here we have written two examples. in the first one we are using OpenFile() method present in the os package while in the second one we are using the Stat() method present in the os package respectively. Method 1: Using OpenFile() Method In this method, we will use the OpenFile() function to check the write permission of a file. This function opens a file with the given name and options, and returns a pointer to a File structure. Syntax func OpenFile(name ... Read More
Testing is a major step for the successful delivery of any application. On the basis of the level of execution of testing, we can classify testing into two categories − System Testing and Acceptance Testing. Read this article to learn more about system testing and acceptance testing and how they are different from each other. What is System Testing? System Testing is a type of testing which is used to validate the functionality of a developed software product. It is also known as black box testing. This testing involves the behavioral as well as functional testing of the software product ... Read More
Syntax defines the rules and regulations that help write any statement in a programming language, while semantics refers to the meaning of the associated line of code in the programming language. Read this article to learn more about syntax and semantics and how they are different from each other. What is Syntax? In a programming language, Syntax defines the rules that govern the structure and arrangement of keywords, symbols, and other elements. Syntax doesn't have any relationship with the meaning of the statement; it is only associated with the grammar and structure of the programming language. A line of ... Read More
In golang we have different inbuild function like Stat(), Open() and mkdir() to check whether a directory exist or not . Here we are using three functions. in the first one we are using the Stat() function present in the os package while in the second and third example we are using Open() and mkdir() function respectively to implement the result. Method 1: Using os.stat() Method The os package provides the Stat() function to get information about a file or directory. If the directory exists, the function returns a FileInfo structure, otherwise, it returns an error. Syntax func ... Read More
