wireguard-tools needs to use newer bash in El Capitan

[treble2019]

El Capitan has bash version 3.2.57(1)-release from /bin/bash (presume from xcode)

Install wireguard-tools in macports 2.6.2. It installs OK.

when one runs

wg-quick up wg0

(it complains that bash is too old and needs newer bash. Not the exact error message. sorry)

Not sure why it does not automatically use the bash installed in

/opt/local/bin/bash

I had to go to Terminal -> Preferences

Shell opens with

. -> Default login shell

. -> Command (complete path) - change here to /opt/local/bin/bash

now

wg-quick

works fine

Can you post the contents of your $PATH environment variable?

It should be look something like:

$ echo $PATH
/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

Depending on how you installed MacPorts, your $PATH should be properly set in .bash_profile, .profile, or .bashrc to include /opt/local/bin and /opt/local/sbin at the beginning (see ​https://guide.macports.org/chunked/installing.shell.html#installing.shell.postflight).

​wg-quick executes bash using /usr/bin/env bash. /usr/bin/env looks through the directories in $PATH and uses the first entry matching bash. If your $PATH has /bin before /opt/local/bin, executing bash will use the old, built-in version instead of the newest (the latest version of bash is installed as a dependency of wireguard-tools).

Thanks for the quick response. Seems I had to restart the macOS for this to work. Sorry for the noise. Just pasting for future use.

mg32:~ user32$ echo $PATH
/opt/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/X11R6/bin:/opt/X11/bin


mg32:~ user32$ echo $BASH_VERSION
3.2.57(1)-release


mg32:~ user32$ ls /opt/local/bin/bash
/opt/local/bin/bash

mg32:~ user32$ cat .profile 
PATH="/opt/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/X11R6/bin:/opt/X11/bin"
export PATH

Please close it. Thanks for your continued support for macports!
