user_ip=$ (who-u am I 2>/dev/null | awk ' {print $NF} ' | sed-e ' s/[()]//g ')
If ["$USER _ip" = ""];then
User_ip= ' hostname '
Fi

if [!-d/tmp/user_history];then
Mkdir/tmp/user_history
Chown Root.root/tmp/user_history
chmod 777/tmp/user_history
Chattr +a/tmp/user_history
Fi

if [!-d/tmp/user_history/${logname}];then
Mkdir-p/tmp/user_history/${logname}
Fi

Export histtimeformat= '%F%T '
Export histsize= ' 40960 '
time=$ (date ' +%y%m%d-%h:%m:%s ')
Export histfile= "/tmp/user_history/${logname}/${user_ip}[$time]"
chmod 600/tmp/user_history/${logname}/*history* 2>/dev/null
