tail of file

英 [teɪl ɒv faɪl]

美 [teɪl əv faɪl]

【计】文件尾部

Two commands allow you to display either the first part ( head) or last part ( tail) of a file.
可以使用两个命令显示文件的开始部分（head）或结束部分（tail）。
The tail utility prints the last part of each file ( 10 lines by default).
tail工具打印每个文件的最末尾部分的内容（默认是10行）。
This tells tail to print the last ten lines of the specified file but, instead of exiting, it waits for more text to appear in the file and prints it as it appears.
该选项告诉tail打印指定文件的最后10行，但是它不仅打印已有的内容，还会等待该文件中将要出现的更多内容，并对其进行打印。
Another common use of tail is to follow a file using the-f option, usually with a line count of1.
tail的另一个常见用法就是使用-f选项跟踪（follow）文件，通常使用一个行计数1。
