* 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 ~/.bashrc
didn'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 several
options to control command history behavior. Set corresponding variables in
your ~/.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, so
I 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.
