On one of my servers I see this when I log in. What does this mean and how can I get it to go away? Everything seems to work fine, but none of my other machines give this error.

-bash: HISTSIZE: readonly variable
-bash: HISTSIZE: readonly variable
-bash: HISTFILESIZE: readonly variable

weird. paste ~/.bashrc

and maybe
/etc/profile
and grep for HIST through /etc/profile.d/

Please post the contents of any of these files that exist:

• /etc/profile
• ~/.bash_profile
• ~/.bash_login
• ~/.profile
• ~/.bashrc

Well it is my /etc/profile but I'm still confused. This exact /etc/profile is on all my machines, but I only get the error for one particular machine.
