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; } [1] http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html -- mailto:moos...@gmail.com
