history

[william benton]

when I log into free bsd I am in the sh shell. i type history at the command line and the machine says history not found. If I type h at the command line it works like i expect the history command to work. In the csh or tcsh shells history works as well as h. why does entering history at the command line work in the csh and tcsh  shells  but not in the sh shell. Considering that all three shells seem to have the same .cshrc file?
