Set awk output to variable in fish shell


linux unix awk gawk fish

scala is going into the background, starting a REPL because it thinks stdin is a terminal. This works for me:

set installed_version (scala -version 2>&1 < /dev/null | awk 'NR==1{ print $5 }')echo $installed_version

linux unix awk gawk fish

This is fish bug #1949 - fish doesn't run command substitutions in a subprocess, and so leaves stdin connected to the tty. Because of that, some tools don't behave as the should.

Joe Hildebrand's workaround (explicitly redirect </dev/null) is the right thing to do currently.
