Can solve the problem of file scrolling in Linux？

[hz-kelpie]

like the file'/root/.bash_history'

when my '/root/.bash_history' start roll

root@kelpie-btf:~# wc -l /root/.bash_history 

2000 /root/.bash_history

root@kelpie-btf:~# echo $HISTSIZE

1000

this util work abnormal ,but "tail -f /root/.bash_history " can still work

this is my config

t, err := tail.TailFile(p, tail.Config{
	Location: &tail.SeekInfo{
		Offset: 0,
		Whence: io.SeekEnd,
	},
	ReOpen:      true,
	Follow:      true,
	Poll:        true,
	MustExist:   false,
	Pipe:        false,
	MaxLineSize: 10000
})
