+* Command history.
+
+Bash allow accessing to command that you type previously. There are exist
+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 neediness, 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.
