uname output: Linux linmac2 4.15.5-1-ARCH #1 SMP PREEMPT Thu Feb 22 22:15:20
UTC 2018 x86_64 GNU/Linux
Machine Type: x86_64-unknown-linux-gnu
Bash Version: 4.4
Patch Level: 19
Release Status: release
Description:
Bash rejects valid function definitions
Repeat-By:
$ func() true
bash: syntax error near unexpected token `true'
# Variant#2
$ func() { true }
> ^C
Both forms seem to be valid per [1] and are accepted by (at least)
ash, zsh and mksh
Worth noting that the Variant#2 can be made to work in bash with an addition
of a semicolon:
$ func() { true; }
