-*- outline -*-* How override PS1, PS2?When loading bash read ~/.bash_profile and ~/.bashrc.Put at end of these files PS1='\u@\H$ 'When xterm start bash - it start as non-login. So ~/.bash_profile and ~/.bashrcdidn't read. To workaround this use $ xterm -e bash -i -c "mc -x"That make bash interactive and init file was readed.* Command history.Bash allow accessing to command that you type previously. There are severaloptions to control command history behavior. Set corresponding variables inyour ~/.bashrc file (which is read by interactive shell): # ignorespace do not save lines that start with space # erasedups all previous lines matching the current line to be removed from # the history list before that line is saved export HISTCONTROL=igrorespace:erasedups export HISTIGNORE=" ?cd *":"e *":"sudo mv *":"sudo rm *":"sudo cp *":"sudo mkdir *":"sudo chmod *":"sudo chown *":ls:pwd:"vlc*"There are another options, with default values (which satisfy my needs, soI don't put they to ~/.bashrc): export HISTFILE=~/.bash_history # where is command history stored export HISTFILESIZE=500 # how many lines been in $HISTFILE export HISTSIZE=500 # how many lines been stored in bash process** mc (GNU Midnight Commander).You can also set special history rules for mc subshell in ~/.mc/bashrc file.
