Shell – Show message when cd into specific directory

cd-commandshell

How can I display a message when I cd into a specific directory? This directory is a local one, and I just need a reminder when I go into it from the terminal.

If I were you, I would toy around with something like that in my shell configuration file (e.g. ~/.bashrc):

reminder_cd() {
    builtin cd "$@" && { [ ! -f .cd-reminder ] || cat .cd-reminder 1>&2; }
}

alias cd=reminder_cd

This way, you can add a .cd-reminder file in each directory you want to get a reminder for. The content of the file will be displayed after each successful cd to the directory.

gim@tenebreuse ~/tmp % echo 'warning: this directory is pure junk' > .cd-reminder
gim@tenebreuse ~/tmp % cd ..
gim@tenebreuse ~ % cd tmp
warning: this directory is pure junk
gim@tenebreuse ~/tmp %

You can use

cd -

or you could use

cd "$OLDPWD"

Bash – Creating an alias to Change Directory and have that directory be the current working directory in new terminal tabs

You have to go another way. Add a line at the end of your .bashrc that changes directory in the last directory the previous bash instance had as CWD (current working directory).

A line like this worked for me:

cd $(readlink  "/proc/$(echo -n $(ps -u $(whoami) -eo stat,pid,cmd | awk '$3 == "'$(which bash)'" && $1 ~ /\+/{print $2}' | sort | head -1))/cwd")

Explanation:

cd $(...): changes directory to whatever is determined below
readlink /proc/$(...)/cwd: reads the link where /proc/pid/cwd points to (current working directory)
echo -n $(...): removes the trailing newline
ps -u $(whoami) -eo stat,pid,cmd: shows my process in a simple format
awk '$3 == "'$(which bash)'" && $1 ~ /\+/{print $2}' if it's a bash and bash is in the foreground process group (indicated by the + in the stat field), then print the pid
sort | head -1 we want only the lowest pid

Edit:

In your case this might be a better solution:

cd $(readlink /proc/$(pgrep -n meteor)/cwd)

It determines the pid of the newest instance of meteor and changes to this current working directory.
