Hi, I come into unix with csh, but i switch to bash . I want to clear my command history for each session, history -c, but for some reason this doesn't work in the .bashrc file. I know that the file is running after I type bash on my csh command line because I get the hello back. If I am already in bash and type source .bashrc, then it will work perfectly. What's going on?

#.bash
set -o vi
PS1="\H"\.ba."\!"\>
history -c
source .aliases
echo HELLO
