This bug occurs only if return is not the last command in the function. >How-To-Repeat: #!/bin/sh -e f() { return 1 : } if f; then :; fi echo END I think this script should print "END", but is does not. It works as expected after changing function f to f() { return 1 } or f() { return 1 || : : } >Fix: >Release-Note: >Audit-Trail: >Unformatted:
