osx - How is the PATH env variable set when opening a BASH shell in Terminal.app on OS X? -

Whether startup script- In that order when the PATH variable is set to OS Bash Shell in Terminal.App on X?

I have got the criminal secret secret code / usr / libexec / path_helper Appears in the / etc / path and /etc/paths.d/ in that directory.

The first bash source / etc / profile that executes the following code:

  If [-x / Usr / libexec / path_helper]; So eval `/ usr / libexec / path_helper -s` # The above line is a secret sauce, to say that ... # adds the default PATH value to the file / etc / paths # then read / etc / Paths.d / directory And the # directory (one per line) listed in each file is linked to the pathfind if ["$ {BASH-no}"! = "No"]; Then [-r / etc / bashrc] & amp; Amp; . / Etc / bashrc fi  

next to bash ~ / .bash_profile , ~ / .bash_login , and ~ / .profile .

List these steps, PATH is created as such:

1. Enter the directory in the / etc / paths To PATH
2. The directory is listed in the file /etc/paths.d/ attached to PATH - Note, this is added in comparison to being predetermined.
3. In various PATH = {DIR_2_ADD}: "$ {PATH}" my ~ / .bash_profile and ~ / .bashrc files are already done PATH
