如何仅打印文件最后一行?
$ cat file | awk END{print}
利用适当的工具从事这项工作。 由于你想要获得档案的最后一行,细节是工作的适当工具,特别是如果你拥有大量档案的话。 在本案中,木舟卷宗处理算法更为有效。
tail -n 1 file
如果你真的想要使用 a,
awk END{print} file
EDIT:tail -1 file
deprecated
是否需要为此使用<代码>awk? 为什么不只使用<代码>尾——n 1 我的File?
摘录档案最后一行:
编辑: www.un.org/Depts/DGACM/index_french.htm 姓名:<0>
详细情况:tail -1级档案 姓名:<0>
a. 使用:子: awk END{打印} 姓名:<0>
也可通过<条码>实现。 然而,我个人建议使用<代码>尾或wk
。
无论如何,如果你希望通过<条码>-条码>来做,这有两种方式:
方法1:
sed $!d filename
方法2:
sed -n $p filename
在此,档案名称是可分析数据的档案名称。
