linux开启user_cmd功能记录用户所有操作指令到log message中

转载与曹阳：

修改如下/etc/下的如下文件，或者用户目录下的对应/root/.bash_profile等文件

bash.bashrc:export PROMPT_COMMAND='msg=$(history 1 | { read x y; echo "$y"; });user=$(whoami);loginuser=$(who am i); logger -t user_cmd "${msg} by ${user} from [$loginuser]"'

csh.cshrc.local:alias precmd 'set msg = `history 1|cut -f3-|sed -e "s|{||g" | sed -e "s|}||g"` ; set user = `whoami` ; set loginuser = `who am i`; logger -t user_cmd "${msg} by ${user} from [$loginuser]" >/dev/null'

ksh.kshrc:export PROMPT_COMMAND='msg=$(history 1 | { read x y; echo "$y"; });user=$(whoami);loginuser=$(who am i); logger -t user_cmd "${msg} by ${user} from [$loginuser]"'

 

生效后，效果如下：
