Automatically acquire the operation log in the terminal when logging in to Linux

This is the first post in a long time. Recently, I'm playing with ubuntu mate installed on gpd-micropc.


I was looking for a way to automatically get the operation log in the terminal. At first I thought I should write a script command in .bashrc, but it doesn't seem to work. .. I found various articles that I searched for and that were helpful. How do I log all input and output in a terminal session?


ubuntu-mate installed on gpd micropc

OS: Ubuntu 19.10 eoan                                                                                                   
Kernel: x86_64 Linux 5.3.0-40-generic
Shell: bash
DE: MATE 1.22.2
CPU: Intel Celeron N4100 @ 4x 2.4GHz
GPU: Mesa DRI Intel(R) UHD Graphics 600 (Geminilake 2x6)-

What i did

1. Create rsyslog configuration file

Since the log will be output with the logger command, create a configuration file below

vim /etc/rsyslog.d/bash.conf


local6.*    /var/log/commands.log

2. Add .bashrc

Add the following to .bashrc under the home directory of the user whose operation log is to be acquired.

vim /home/hoge(Target user)/.bashrc

/home/hoge(Target user)/.bashrc

whoami="$(whoami)@$(echo $SSH_CONNECTION | awk '{print $1}')"export PROMPT_COMMAND='RETRN_VAL=$?;logger -p local6.debug "$whoami [$$]: $(history 1 | sed "s/^[ ]*[0-9]\+[ ]*//" ) [$RETRN_VAL]"'

3. Restart the rsyslog service

Restart the rsyslog service

systemctl restart rsyslog.service 

4. Create a configuration file for log rotation

Create a config file to rotate daily with logrotate.d

vim /etc/logrotate.d/commands


»-rotate 7
»-su root root                                                                                                          


Read .bashrc

source .bashrc 

Confirm that the file is created under / var / log as shown below.

ls -la /var/log/commands.log*
-rw-r-----1 syslog adm 4753 March 15 19:34 /var/log/commands.log

Mar 15 19:34:39 hoge hoge: [email protected] [3457]: 2020-03-15 19:34:37 source .bashrc  [0]
Mar 15 19:36:56 hoge hoge: [email protected] [3457]: 2020-03-15 19:36:56 ls -la /var/log/commands.log* [0]


I'm wondering if I can logrotate. .. After that, I want the output like the script command. ..
