Golang : Rename part of filename
This simple tutorial is a code fragment extract from previous tutorial for scanning and renaming partial filenames showing how you can rename part of a filename in Go.
var f os.FileInfo
path := `\targetfile.txt`
// check each file if starts with the word "dumb_"
// depending on your needs
// you can replace HasPrefix with http://golang.org/pkg/strings/#Contains or http://golang.org/pkg/strings/#HasSuffix
if strings.HasPrefix(f.Name(), "dumb_") {
base := filepath.Base(path) // get the file's basename
dir := filepath.Dir(path)
renameto := filepath.Join(dir, strings.Replace(base, "dumb_", "smart_", 1))
os.Rename(path, renameto)
}
