Functions

func CopyDir

func CopyDir(src string, dst string) error

CopyDir recursively copies a directory tree, attempting to preserve permissions. Source directory must exist, destination directory must *not* exist. Symlinks are ignored and skipped. Credit @m4ng0squ4sh https://gist.github.com/m4ng0squ4sh/92462b38df26839a3ca324697c8cba04

func CopyFile

func CopyFile(src string, dst string) error

CopyFile copies the contents of the file named src to the file named by dst. The file will be created if it does not already exist. If the destination file exists, all it's contents will be replaced by the contents of the source file. The file mode will be copied from the source and the copied data is synced/flushed to stable storage. Credit @m4ng0squ4sh https://gist.github.com/m4ng0squ4sh/92462b38df26839a3ca324697c8cba04

func FgrepStringInFile

func FgrepStringInFile(fullPath string, needle string) (bool, error)

FgrepStringInFile is a small hammer for looking for a literal string in a file. It should only be used against very modest sized files, as the entire file is read into a string.

func FileExists

func FileExists(name string) bool

FileExists checks a file's existence

func ListFilesInDir

func ListFilesInDir(path string) ([]string, error)

ListFilesInDir returns an array of files found in a directory

func PurgeDirectory

func PurgeDirectory(path string) error

PurgeDirectory removes all of the contents of a given directory, leaving the directory itself intact.

func RandomFilenameBase

func RandomFilenameBase() string

RandomFilenameBase generates a temporary filename for use in testing or whatever. From https://stackoverflow.com/a/28005931/215713

func ReplaceStringInFile

func ReplaceStringInFile(searchString string, replaceString string, origPath string, destPath string) error

ReplaceStringInFile takes search and replace strings, an original path, and a dest path, returns error
