How to clear the history of Linux commands

Article Title: how to clear the history of Linux commands. Linux is a technology channel of the IT lab in China. The basic classification steps include desktop applications, Linux system management, kernel research, embedded systems, and open-source systems:
　
1. Create a file to store Common commands, such as/root/history.txt. Write Common commands as text. Each Command occupies one line.
　
2. Run history-c on the terminal to clear messy history records
　
3. Run history-r/root/history.txt and read the command as the history of the current bash.
　
4. Run history to get a neat command list, for example:
　
　　

[root@localhost windata]# history -c [root@localhost windata]# history -r /root/history.txt [root@localhost windata]# history 1 history -r /root/history.txt 2 mount -t msdos -o iocharset=gb2312 /dev/sda1 /mnt/usb 3 mount -t vfat -o iocharset-gb2312 /dev/hda5 /mnt/windata 4 umount /mnt/windata 5 mount -t vfat -o iocharset-gb2312 /dev/hda5 /mnt/windata 6 cd /mnt/windata 7 history [root@localhost windata]#

5. In the future, commands will be messy. Repeat steps 1-4 to make the commands clear.
