If I do:
#!/usr/bin/env bash
. "$HOME/.foo/bar.sh"
will it invoke/load that bar.sh script with sh?
is it any different than:
#!/usr/bin/env bash
source "$HOME/.foo/bar.sh"
-
Both load the script into the current shell, whatever that may be (wherever the syntax is valid); no other shell is invoked.Ignacio Vazquez-Abrams– Ignacio Vazquez-Abrams2018-05-12 20:48:49 +00:00Commented May 12, 2018 at 20:48

If you source another script in a bash script, then it's bash that sources that other script. The two command that you list are equivalent in bash.

yeah still trying to figure out why sh is being run from a bash parent shell lol thanksAlexander Mills– Alexander Mills2018-05-12 20:31:08 +00:00Commented May 12, 2018 at 20:31

It is worth noting that the
sourcebuilt-in (but not.) is a Bash extension, possibly inspired by the command of the same name in csh. It is not in the specifications for the POSIX shell.John Bollinger– John Bollinger2018-05-12 23:18:37 +00:00Commented May 12, 2018 at 23:18 -
@JohnBollinger I believe this is where the question actually comes from. Alexander is aware that
sourceis abashextension and that.is not, so he wonders if.would invokesh(which it doesn't).2018-05-13 06:27:25 +00:00Commented May 13, 2018 at 6:27
