I try to set the $PATH reference to the current working directory, one machine work as expected, but another machine is not.

basically, I have set below line in .bashrc

export PATH=$PWD/bin:$PATH

if I move directory to /123, I expected that the $PATH will updated to /123/bin:$PATH but it isn't.

Are there anyway to make it read the current $PWD to use in $PATH?

Add the following line in ~/.bashrc to add ./bin directory in PATH

export PATH=./bin:$PATH

Next you need to run in terminal source ~/.bashrc to affect the change.

  • . should be ./bin if you reread their question. – Thomas Ward Dec 13 '13 at 19:23
  • @ThomasW. Thanks for correcting me, I am editing it. But at his first line he mentioned about current directory only. And never asked for ./bin/ in every directory. – sourav c. Dec 13 '13 at 19:25

If you want to be in the subdirectory bin of the current directory that is ./bin so:

export PATH=./bin:$PATH

The PATH variable is not automatically updated. When you move a folder such as /home/$USER/bin to /home/$USER/notbin you'll have to manually update your $PATH environment variable. That will fix the issue.

It may also help to manually update the full directory path you're adding to $PATH. If your directory you're adding to $PATH is /home/$USER/stuff/programs/someprogram/bin then $PWD won't really help you that much. Therefore, knowing where your stuff is stored, and putting in the full path, will make almost-certain that the correct directory ends up in the $PATH variable. (since .bashrc is located in your ~ dir, $PWD inside of ~/.bashrc will always be your home directory, when its called.)
