The steps are as follows:

1, create a file to store commonly used commands, such as/root/history.txt, write the common commands as text, each command occupies one line

2, run history-c in the terminal, clean up the messy history record

3, run History-r/root/history.txt, read the command as the history of the current bash

4, run history, you get a neat list of commands, such as:

[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, after the chaos of the order, repeat the 1-4 steps, but also to make the command very clear.
