This function returns the File descriptor. First, we create a file and then use the WriteString function to write the bytes into a newly created file. The method returns several bytes written and errors, if any. It writes a string rather than a slice of bytes. Now, if you check in the file directory, there is a new file called test.

To write bytes into the file in Golang, use the os. Write function. The Write function writes len b bytes to the File. It returns several bytes written and an error, if any. The Write function returns a non-nil error when n!

See the following example. The os. Write method writes a slice of bytes to a file named test. You can change the directory however you want. After running your program, if you open the test.

To write strings line by line, we can use the range function. Then we use fmt. Fprintln function to write strings line by line. Now a dependency of a module can be of two kind.
