Useful tips for profile

If you are familiar with unix or linux, you know how important profile settings are. If I were to build a new server environment, I would check the profile first. The following settings are the ones I set up mainly in ksh or bash environments.

.bash_profile

stty erase "^H" kill "^U" intr "^C" eof "^D"
stty hupcl ixon ixoff
stty cs8 -istrip
