==DESCRIPTION==<br />
<pre><br />
DESCRIPTION<br />
Many programs read input from the user a line at a time. The GNU History library is able to keep track of those lines,<br />
associate arbitrary data with each line, and utilize information from previous lines in composing new ones.<br />
<br />
</pre><br />
<br />
=OPTIONS=<br />
<pre><br />
-c 清空当前历史命令 clear the history list by deleting all of the entries<br />
-d offset 删除历史记录中第offset个命令 delete the history entry at position OFFSET. Negative<br />
offsets count back from the end of the history list<br />
<br />
<br />
-N: 显示历史记录中最近的N个记录；<br />
<br />
-a：将历史命令缓冲区中命令写入历史命令文件中；<br />
-r：将历史命令文件中的命令读入当前历史命令缓冲区；<br />
-w：将当前历史命令缓冲区命令写入历史命令文件中;<br />
<br />
-n<filename>：读取指定文件<br />
<br />
</pre><br />
=部分删除操作 清除命令执行操作的历史记录=<br />
<pre><br />
1.vim ~/.bash_history<br />
该文件即为历史记录存储文件，我们随意修改<br />
<br />
2.修改后再次 history 查看，发现并没有变化。原因：缓存<br />
执行：history -r<br />
读取历史文件并将其内容添加到历史记录中，即重置文件里的内容到内存中，完成修改！<br />
</pre><br />
=完全清除命令执行操作的历史记录=<br />
<pre><br />
1.清理历史记录（只是清理了表层，可在.bash_history找到回）<br />
history -c<br />
<br />
<br />
2.清理记录历史的记录文件内容<br />
<br />
echo " " > .bash_history <br />
echo > ~/.bash_history<br />
