从symlink目录运行带有相对路径的命令

Question

I've got a directory structure like this:

bin
  drush
build -> vendor/drupal/core
vendor
  drupal
    core

So as you see, build is a symlink to the core directory. drush is an executable file. I need to be able to cd into build and call drush from there.

But if I do this:

cd build
../bin/drush

This doesn't work, because .. points to vendor/drupal directory, because when I cd into build , it in fact goes to vendor/drupal/core , of course.

I know I can call it this way: ../../../bin/drush , but is there some kind of workaround to make .. point to the root, not the actual parent?

Answer 1

You can create an another symlink in the folder "drupal" on the executable drush. So with this way, you can call it from "build".

$ cd vendor/drupal/
$ ln -s absolute_path/bin/drush dummy-drush 
$ cd build 
$ ./dummy-drush

Solution 1 : If you don't want to create anything in vendor, maybe it's better to create an alias which allows to you to execute drush (be careful to give the good path).

Solution 2 :

If the directory bin in your example is not the folder "/bin" from the root, you can add it in your PATH in order to execute every executable .

$ export PATH=$PATH:/personal_bin/
$ cd bin
$ ln -s drush dummy-drush
