# tail functionality in Go
|
||
|
|
|
||
|
|
nxadm/tail provides a Go library that emulates the features of the BSD `tail`
|
||
|
|
program. The library comes with full support for truncation/move detection as
|
||
|
|
it is designed to work with log rotation tools. The library works on all
|
||
|
|
operating systems supported by Go, including POSIX systems like Linux and
|
||
|
|
*BSD, and MS Windows. Go 1.9 is the oldest compiler release supported.
|
||
|
|
|
||
|
|
A simple example:
|
||
|
|
|
||
|
|
```Go
|
||
|
|
// Create a tail
|
||
|
|
t, err := tail.TailFile(
|
||
|
|
"/var/log/nginx.log", tail.Config{Follow: true, ReOpen: true})
|
||
|
|
if err != nil {
|
||
|
|
panic(err)
|
||
|
|
}
|
||
|
|
|
||
|
|
// Print the text of each received line
|
||
|
|
for line := range t.Lines {
|
||
|
|
fmt.Println(line.Text)
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|

## History
|
||
|
|
|
||
|
|
This project is an active, drop-in replacement for the
|
||
|
|
[abandoned](https://en.wikipedia.org/wiki/HPE_Helion) Go tail library at
|
||
|
|
[hpcloud](https://github.com/hpcloud/tail). Next to
|
||
|
|
[addressing open issues/PRs of the original project](https://github.com/nxadm/tail/issues/6),
|
||
|
|
nxadm/tail continues the development by keeping up to date with the Go toolchain
|
||
|
|
(e.g. go modules) and dependencies, completing the documentation, adding features
|
||
|
|
and fixing bugs.
