Is there a api like 'path.resolve' in node? Or something can do the same?
For Example (nodejs code): path.resolve("~/sample.sh") Should got: /home/currentuser/sample.sh

The absolutePath function works by beginning at the starting folder and moving up one level for each "../" in the relative path. Then it concatenates the changed starting folder with the relative path to produce the equivalent absolute path.
In simple words, an absolute path refers to the same location in a file system relative to the root directory, whereas a relative path points to a specific location in a file system relative to the current directory you are working on.
An absolute path is defined as specifying the location of a file or directory from the root directory(/). In other words,we can say that an absolute path is a complete path from start of actual file system from / directory. Relative path is defined as the path related to the present working directly(pwd).
Resolving ~ (denoting the user home) is a different story, and usually it's the shell that resolves this. For details see Expand tilde to home directory.
If you want to do it from Go code, you may use the user.Current() function to get details about the current user, including its home folder which will be User.HomeDir. But still, you'll have to handle replacing this yourself.
Original answer follows.
You may use path.Join() or filepath.Join().
For example:
base := "/home/bob" fmt.Println(path.Join(base, "work/go", "src/github.com")) Output:
/home/bob/work/go/src/github.com You may use path.Clean() and filepath.Clean() to "remove" dots . and double dots .. from your path.
You may use filepath.Abs() to resolve relative paths and get an absolute (prepending the working directory if it's not absolute). filepath.Abs() also calls Clean() on the result.
For example:
fmt.Println(filepath.Abs("/home/bob/../alice")) Outputs:
/home/alice <nil> Try the examples on the Go Playground.
