Can I associate my command history based on my cwd

Question

I often navigate between multiple directories in a bash session. Sometimes upto 4. For each directory I am in I often have an exclusive set of commands that I fire and this set can be between 7 and 10 commands. I was wondering if it is possible to create an association between my bash command history and the cwd in which those commands were fired. Appreciate any suggestions.

Answer 1

Use the following re-definition for cd and and put these lines into .bashrc:

            HISTFILE=$HOME/.bash_history.`echo $PWD|sed -e 's/\//_/g'`
            cd () {
                history -a
                command cd "$@"
                HISTFILE=$HOME/.bash_history.`echo $PWD|sed -e 's/\//_/g'`
                history -c
                history -r
            }

Answer 2

You can use PROMPT_COMMAND to check $PWD and take appropriate action, something like this:

PROMPT_COMMAND='if [[ $PWD =~ /usr/share ]]; then echo take action in /usr/share; fi'
