Functions

func Append 

func Append(dst string, src string) error

Append creates or appends the dst file or dir, filled with content from src file. If the dst file already exists, it is truncated. If the dst file does not exist, it is created with mode 0666 (before umask). If the dst dir does not exist, it is created with mode 0755 (before umask). parent dirs will not be created, otherwise, use AppendAll instead.

func AppendAll 

func AppendAll(filename string, data []byte) error

AppendAll appends data to a file named by filename. If the file does not exist, AppendAll creates it with mode 0666 (before umask) If the dir does not exist, AppendAll creates it with 0755 (before umask) (before umask); otherwise AppendAll appends it before writing, without changing permissions.

func AppendAllFrom 

func AppendAllFrom(filename string, r io.Reader) error

AppendAllFrom appends data to a file named by filename from r until EOF or error. If the file does not exist, AppendAllFrom creates it with mode 0666 (before umask) If the dir does not exist, AppendAllFrom creates it with 0755 (before umask) (before umask); otherwise AppendAllFrom appends it before writing, without changing permissions.

func AppendAllIfNotExist 

func AppendAllIfNotExist(path string) (*os.File, error)

func AppendFileAll 

func AppendFileAll(filename string, data []byte, dirperm, fileperm os.FileMode) error

AppendFileAll is the generalized open call; most users will use AppendAll instead. It appends data to a file named by filename. If the file does not exist, AppendFileAll creates it with permissions fileperm (before umask) If the dir does not exist, AppendFileAll creates it with permissions dirperm (before umask) otherwise AppendFileAll appends it before writing, without changing permissions.

func AppendFileAllFrom 

func AppendFileAllFrom(filename string, r io.Reader, dirperm, fileperm os.FileMode) error

AppendTruncate truncates the original src file in place after appending or creating a copy dst, instead of moving the src file to dir and optionally creating a new one src.

func AppendTruncateAll 

func AppendTruncateAll(dst string, src string) error

If the dst file does not exist, it is created with mode 0666 (before umask). If the dst dir does not exist, it is created with mode 0755 (before umask). parent dirs will not be created, otherwise, use CopyAll instead.

func CopyAll 

func CopyAll(dst string, src string) error

CopyAll creates or truncates the dst file or dir, filled with content from src file. If the dst file already exists, it is truncated. If the dst file does not exist, it is created with mode 0666 (before umask). If the dst dir does not exist, it is created with mode 0755 (before umask).

CopyFile is the generalized open call; most users will use Copy or Append instead. It opens the named file or directory with specified flag (O_RDONLY etc.). CopyFile copies from src to dst. parent dirs will not be created, otherwise, use CopyFileAll instead.

func CopyFileAll 

func CopyFileAll(dst string, src string, flag int, dirperm, fileperm os.FileMode) error

CopyFileAll is the generalized open call; most users will use CopyAll or AppendAll instead. It opens the named file or directory with specified flag (O_RDONLY etc.). If the dst file does not exist, and the O_CREATE flag is passed, it is created with mode fileperm (before umask). If the dst directory does not exist, it is created with mode dirperm (before umask). If successful, methods on the returned File can be used for I/O. If there is an error, it will be of type *PathError.

func CopyRename

It can be used when some program can‐ not be told to close its logfile and thus might continue writing (appending) to the previous log file forever. Note that there is a very small time slice between copying the file and truncating it, so some logging data might be lost.

If pattern includes a "*", the random string replaces the last "*". Multiple programs calling NextFile simultaneously will not choose the same file.

If the dir does not exist, it is created with mode 0755 (before umask).

func RenameFileAll 

func RenameFileAll(oldpath, newpath string, dirperm os.FileMode) error

RotateFile logrotate reads everything about the log files it should be handling from the series of con‐ figuration files specified on the command line. Each configuration file can set global options (local definitions override global ones, and later definitions override earlier ones) and specify rotatefiles to rotate. A simple configuration file looks like this:

func NewRotateFile 

func NewRotateFile(layout string) *RotateFile
Example 
package main

import (
	"time"

	os_ "github.com/searKing/golang/go/os"
)

func main() {
	file := os_.NewRotateFile("log/test.2006-01-02-15-04-05.log")
	defer file.Close()
	file.MaxCount = 5
	file.RotateInterval = 5 * time.Second
	file.MaxAge = time.Hour
	file.FileLinkPath = "log/s.log"
	for i := 0; i < 10000; i++ {
		time.Sleep(1 * time.Millisecond)
		file.WriteString(time.Now().String())
		//if err := file.Rotate(false); err != nil {
		//	fmt.Printf("%d, err: %v", i, err)
		//}
	}
}

Output:

func NewRotateFileWithStrftime 

func NewRotateFileWithStrftime(strftimeLayout string) *RotateFile
Example 
package main

import (
	"time"

	os_ "github.com/searKing/golang/go/os"
)

func main() {
	file := os_.NewRotateFileWithStrftime("log/test.%Y-%m-%d-%H-%M-%S.log")
	file.MaxCount = 5
	file.RotateInterval = 5 * time.Second
	file.MaxAge = time.Hour
	file.FileLinkPath = "log/s.log"
	for i := 0; i < 10000; i++ {
		time.Sleep(1 * time.Millisecond)
		file.WriteString(time.Now().String())
		//if err := file.Rotate(false); err != nil {
		//	fmt.Printf("%d, err: %v", i, err)
		//}
	}
}

Output:

func (*RotateFile) Close 

func (f *RotateFile) Close() error

Close satisfies the io.Closer interface. You must call this method if you performed any writes to the object.

func (*RotateFile) Rotate 

func (f *RotateFile) Rotate(forceRotate bool) error

Rotate forcefully rotates the file. If the generated file name clash because file already exists, a numeric suffix of the form ".1", ".2", ".3" and so forth are appended to the end of the log file

This method can be used in conjunction with a signal handler so to emulate servers that generate new log files when they receive a SIGHUP

func (*RotateFile) Write 

func (f *RotateFile) Write(b []byte) (n int, err error)

func (*RotateFile) WriteAt 

func (f *RotateFile) WriteAt(b []byte, off int64) (n int, err error)

WriteAt writes len(b) bytes to the File starting at byte offset off. It returns the number of bytes written and an error, if any. WriteAt returns a non-nil error when n != len(b).

If file was opened with the O_APPEND flag, WriteAt returns an error.

func (*RotateFile) WriteString 

func (f *RotateFile) WriteString(s string) (n int, err error)

WriteString is like Write, but writes the contents of string s rather than a slice of bytes.

	RotateModeNew RotateMode = iota

	// RotateModeCopyRename Make a copy of the log file, but don't change the original at all. This option can be
	// used, for instance, to make a snapshot of the current log file, or when some other

	// option will have no effect, as the old log file stays in place.
	// see option: `copy` in https://man7.org/linux/man-pages/man8/logrotate.8.html
	RotateModeCopyRename RotateMode = iota

	// RotateModeCopyTruncate Truncate the original log file in place after creating a copy, instead of moving the
	// old log file and optionally creating a new one. It can be used when some program can‐
	// not be told to close its rotatefile and thus might continue writing (appending) to the
	// previous log file forever. Note that there is a very small time slice between copying
	// the file and truncating it, so some logging data might be lost. When this option is
