# 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)
}
```
See [API documentation](https://pkg.go.dev/github.com/nxadm/tail).
## Installing
go get github.com/nxadm/tail/...
## 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.
## Examples
Examples, e.g. used to debug an issue, are kept in the [examples directory](/examples).
