In golang we can use ioutile.ReadFile() to read the file and for loop timer, we will limit the character numbers to read, Os.Open and bufio.NewReader function to perform the execution as well as file.Read() respectively. In this article we will learn how to use the OS asnd bufio package of Golang to read the specified number of characters from the existing file. Syntax ioutil.ReadFile(file) The ReadFile() function is present in ioutil package and is used to read the given file. The function accepts the file to be read as argument to the function. To read a specified number of ... Read More

In this golang article, we are going to use os.OpenFile() and ioutil.Readfile() to append the given file without truncating it. In the first Example, we are going to Os.Openfile to access the file and then by using file.WriteString function we will append it. In the second Example, we will use ioutil, ReadFile(), ioutil.WriteFile() and Append() functions to perform the same operation on the file without truncating it respectively. Syntax file.read() The Read() function is used to read the contents of a file. The function accepts the file whose contents are to be read as an argument and returns the ... Read More

In Golang, read-only mode refers to a mode of operation in which a file, directory, or device can only be viewed or read, but not modified or deleted. This mode is used to prevent accidental changes in the data. In computer systems, the read-only mode can be set at the file or folder level, or it can be set for an entire disk or partition. In this article, we will use three Examples to open a file in read-only mode. In the first Example we will use open function from the os package, in the second Example we will use ... Read More

In golang we can os.Openfile function of os package and ioutil.WriteFile() function of ioutil package to append a file. Then, we will use WriteString() function to print the result. In this article, we are going to learn how to create a golang programt to open a file in append mode incase the file does not exist. Syntax os.OpenFile(name/path string, flag int, perm FileMode) The OpenFile() function is present in os package. The function accepts three arguments. One is the name of the file that is to be opened followed by the int type instruction used to open a ... Read More

In Go programming language, os and io packages can be used for performing various operations on external files like copying, editing, and even appending them. In this article, we will learn two Examples to open a file in append mode. In the first Example we will use os.OpenFile function from os package and in the second Example we will use ioutil.WriteFile function from ioutil package. Syntax os.OpenFile("test.txt", os.O_APPEND|os.O_CREATE|os.O_WRONLY, 0644) The OpenFile() function is present in os package and is used to open a file. The function accepts the file to be opened as argument to the function along with ... Read More

In Golang, the functions os.openfile () and ioutil.Writefile() are used to access/open a file in read-write mode without truncating it. In this article, we will understand the functionality of these two functions using two different methods. In the first method we will use the OpenFile() function present in os package and In the second method, we will use the WriteFile() function to implement the result. Syntax os.OpenFile() The OpenFile() function is present in os package and is used to open a file. The function accepts the file to be opened as argument to the function along with ... Read More

In Golang, we can use OS functions os.OpenFile(), os.Create() and ioutil.WriteFile to open a write-only file. Here we are going to see three different Examples to understand the functionality of these functions. In the first program we will use the OpenFile() function while in the second and third program, we will use the writeFile() and create() function respectively. Syntax func WriteFile(filename string, data []byte, perm os.FileMode) error The WriteFile() function is present in the ioutil package and is used to write the data in the file. The function accepts the name of file in which data is to be ... Read More

In Golang, repeating a slice of bytes is a common operation that can be useful in many different applications.
