Use 'ps -ef > /path/filename': see http://www.gnu.org/software/bash/man...irections.html and http://tldp.org/LDP/abs/html/io-redirection.html

In BaSH history is saved automagically to your ~/.bash_history (default location) when your shell session ends so there is nothing you have to do. (Also see 'man bash' for 'shopt -s histappend' and 'history -a'.)
