Sorry, I think I have been confusing. This: date echo a | while read ; do sleep 3 & done wait date will run in 0 seconds, with BOTH /bin/sh and /bin/bash This: date while read ; do sleep 3 & done < <(echo a) wait date will run in 3 seconds with /bin/bash and get syntax errors with /bin/sh: syntax error near unexpected token `<' `done < <(echo a)' $ /bin/sh --version GNU bash, version 4.3.46(6)-release (x86_64-unknown-cygwin) Copyright (C) 2013 Free Software Foundation, Inc.
