This came up on comp.unix.shell: There appears to be a parsing problem in bash where the sequence $$'...' is treated as $'...', and $$"..." as $"...", when inside $(...).
$ echo 'x\nx' x\nx $ echo $'x\nx' x x $ echo $$'x\nx' 86293x\nx $ echo $(echo $'x\nx') x x $ echo $(echo $$'x\nx') x x This is with bash 4.4.12... but a quick check shows the same behavior with 4.2.37. -- Christian "naddy" Weisgerber na...@mips.inka.de
