The program will print the contents of test.txt Now the program can be run from any location and it will print the contents of test.txt.ДЇor example, it will work even when I run it from my home directory cd ~/Documents/filehandling package mainДata, err := ioutil.ReadFile('/home/naveen/Documents/filehandling/test.txt') Please change this path to the absolute location of your test.txt. I have modified the program and changed the path to an absolute one in line no. The simplest way to solve this problem is to pass the absolute file path.

Bundling the text file along with the binary.

There are three ways to solve this problem, Since test.txt is not found in the location from which the binary is run, the program complains that it cannot find the file specified. The binary is independent of the source code and it can be run from any location.

What go install does is, it creates a binary from the source code. File reading error open test.txt: no such file or directory If this program is run from any other location, for instance, try running the program from ~/Documents/ cd ~/Documents/ This program will print, Contents of file: Hello World.

If you are not aware of how to run a Go program, please visit to know more. If test.txt is located at ~/Documents/filehandling, then run this program using the following steps, cd ~/Documents/filehandling/ Please run this program from the location where test.txt is present. 14 we convert data to a string and display the contents of the file. 9 of the program above reads the file and returns a byte slice which is stored in data. Please run this program from your local environment as it's not possible to read files in the playground. package mainДЇmt.Println('Contents of file:', string(data)) Create a file filehandling.go with the following contents. test.txt contains the following string Hello World. I have a text file test.txt which will be read from our Go program filehandling.go. I have created a folder filehandling inside my Documents directory by running mkdir ~/Documents/filehandling.Д¬reate a Go module named filehandling by running the following command from the filehandling directory. Let's read a file and print its contents. This is done with the help of the ReadFile function of the ioutil package. One of the most basic file operations is reading an entire file into memory.

Passing the file path as a command line flag.

This tutorial has the following sections. In this tutorial, we will learn about how files can be read using Go. 35 in Golang tutorial series.ДЇile reading is one of the most common operations performed in any programming language.
