Why can't record command containing ssh into /var/log/ssh.log?
 
Code:
vim /etc/profile
export HISTTIMEFORMAT="%Y-%m-%d:%H-%M-%S:  `whoami` : "
export PROMPT_COMMAND='history -a |grep ssh >> /var/log/ssh.log'
sudo touch /var/log/ssh.log
chmod 777 /var/log/ssh.log

Login with a normal user ,to input `cat /var/log/ssh.log` ,why no record in /var/log/ssh.log?

That just puts "history |grep ssh >> /var/log/ssh.log" into the environment variable PROMPT_COMMAND

To write to a file, just execute the command:
Code:
history  |grep ssh >> /var/log/ssh.log
PS. Setting perms on any file to 777 is almost never a good idea
