Go Language (Traverse folder)

This is a creation in Article, where the information may have evolved or changed.

Today is the question of a go language operation file, that is, how to traverse all files under a folder.

The code is as follows

Package Mainimport (    "Path/filepath"    "OS" "    fmt"    "flag") Func getfilelist (path string) {    ERR: = FilePath. Walk (Path, func (path string, f OS). FileInfo, err Error) error {        if f = = nil {return err}        if F.isdir () {return nil}        println (path)        return NI L        })    if err! = Nil {        FMT. Printf ("filepath. Walk () returned%v\n ", err)    }}func main () {    flag. Parse ()    root: = flag. ARG (0)    getfilelist (Root)}

Then traverse the following package folder

Next execute the go run filewalk.gopackage and get the following results

This will get a folder underneath all the sub-files, and then you can go through the OS. Open () opens and reads and writes.
