The example writes a string to a file with ioutil.WriteFile. The opening and closing of the file are handled for us. This is a higher-level convenience function. The outil.WriteFile writes data to the specified file. _, err2 := f.WriteString("My first fav programming languge is Go Lang \nMy second fav programming languge is Java \nMy third fav programming languge is Python\n")Īfter executing the above program, open the 'sample.txt' file and you should able to see the content of the file as below: My first fav programming languge is Go Lang
Let's first create an empty 'sample.txt' file that we want to write upon. The example writes a string to a text file. The File.WriteString function writes the contents of a string to a file. Let's create a 'sample.txt' file and add the following content to it: My first fav programming languge is Go Lang By default, the function breaks the data into lines with line termination stripped. It reads data by tokens the Split function defines the token. The Scanner provides a convenient interface for reading data such as a file of newline-delimited lines of text. Output: G:\GoLang\examples>go run go_example.go Let's create a file named go_example.go and add the following content to it:Ĭontent, err := ioutil.ReadFile("sample.txt") My third fav programming languge is Python
My second fav programming languge is Java My first fav programming languge is Go Lang Let's create a 'sample.txt' file and add the following content to it: The example reads the whole file and prints it to the console.
This function is convenient but should not be used with very large files. The ioutil.ReafFile function reads the whole file into a string.
