This article will explain in detail how to view history commands in linux. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The linux View History command can use the history command, which lists all commands that have been typed. All commands typed by the user are recorded in a file, which is saved in the home directory of the currently logged-in user.

This article operating environment: centos 7 system, thinkpad T480 computer.

In the Linux environment, you can view recently typed commands by pressing the arrow keys up and down. But this method can only be viewed one by one, in fact, the system provides a way to view all the historical commands.

Enter the following command in the terminal to view all commands:

[root@template ~] # history 1 ifconfig 2 vim / etc/ssh/sshd_config 3 / etc/init.d/sshd restart 4 vim / boot/grub/grub.conf 5 vim / etc/selinux/config 6 vim / etc/sysconfig/network-scripts/ifcfg-eth0 7 rm-rf / etc/udev/rules.d/70-persistent-net.rules 8 useradd vsroot 9 echo-e'vsroot\ tALL= (ALL)\ tNOPASSWD: ALL' > > / etc/sudoers 10 yum clean all 11 rm-rf / var/log/yum.log 12 rm-rf / var/lib/yum/* 13 rm-rf / root/install.log 14 rm-rf / root/install.log.syslog 15 rm-rf / var/log/anaconda.*

The history command lists all commands that have been typed, and commands typed by the user are recorded in a file that is saved in the home directory of the currently logged-in user.

The file name is: .bash_history, which is a hidden file.

Cleanup of historical operation commands:

If you do something bad on the server, you can clear it with the "history-c" command, so that others cannot view the historical operation commands when they log in to the terminal.

However, this command does not clear the records saved in the file, so you need to manually delete the records in the .bash _ profile file.
