How to print the current path in Golang
Gutha Vamsi KrishnaOverview
In this shot, we will learn how to get the current path in the working directory.
We will use the Getwd() method provided by the os package in Golang to get the current path.
Return value
The Getwd() method returns two values:
Directory path: The current working directory path.Error: Any error that occurs.
Code
package main
import (
"os"
"fmt"
)
func main() {
//Get working directory path
curdir, err := os.Getwd()
//check if any error occurs
if err != nil {
//display error if
fmt.Println(err)
}
//display the path
fmt.Println(curdir)
}
Code block to capture both error and current directory path
Explanation
In the code above:
- Line 4: We import the
ospackage, which provides functions likeGetwd(). - Line 5: We import the format package
fmt, which is useful for formatting input and output. - Line 11: We call the
Getwd()method and assign the two return variables tocurdiranderr.curdirrepresents the current directory anderrrepresents error. - Line 14: We check if the error
erris present.- Line 15: We print the error
errif an error occurs.
- Line 15: We print the error
- Line 20: We print the current working directory path
curdir.
We can also use _ if we don’t want to use the error value returned by Getwd(), as shown in the code snippet below:
Note: We should only use
_when we are sure there will not be any errors.
package main
import (
"os"
"fmt"
)
func main() {
//Get working directory path
curdir, _ := os.Getwd()
//display the path
fmt.Println(curdir)
}
Code block to capture only current directory path
