Everyone knows the command
cd – everyone uses it several times a day. (OK – not everyone, but every Linux user.) Most of us know, that we can change back to the last directory with
$ cd -
$ pwd /home/maker/docs/sensors $ cd /opt/sensors/bmp280 $ pwd /opt/sensors/bmp280 $ cd - $ pwd /home/maker/docs/sensors
But what if you cd in your project directory and then need to change back into your docs directory? You have to type the whole path. Or do you?
