Bash command logger

I was wondering, out of curiosity, if you can encode the bash script log of the entire command running in a Bash / SSH session. I know that I historyshould log all the teams, but it seems very unreliable!

This morning I was messing around with the following bash script that logs what the user starts in the terminal but does not execute all the commands correctly.

prompt_read() {
  echo -n "$(whoami)@$(hostname):$(pwd)~$ "
  read userinput
}

prompt_read

while :; do
  if [[ $userinput != exit ]]; then
    logger "logit $userinput"
    bash -c "$userinput"
    prompt_read
  else
    kill -1 $PPID
  fi
done

Does anyone know anything that makes teams better and more reliable than history

Greetings

The reason the story seems unreliable to you is because it only records the story at the end of the BASH session, so you might lose commands.

BASH:

HISTFILESIZE=10000 # how many lines of history to store in the history file

HISTSIZE=10000 # how many lines of history to store in a session ( I think )

HISTCONTROL=ignoredups # ignore duplicate commands

shopt -s histappend # append history, rather than having sessions obliterate existing history
PROMPT_COMMAND="history -a;$PROMPT_COMMAND"

, PROMPT_COMMAND history -a , ​​, . shopt -s histappend BASH , .

Here you can find a script here to write all the bash '/ embedded commands in a text file or syslog' without using a patch or special executable.

You can also write directly without syslog to the log file.

It is very easy to deploy, as it is a simple script shell that needs to be called once when initializing "bash".
