This is a configure-time option, but unless your vendor changes it, it's off by default. It can also be changed in a startup file or another file that gets sourced, like bash-completion. > Likewise, hostcomplete seems to be disabled when bash is > non-interactive, which behavior is also not documented. This isn't the case in bash as it's distributed: $ cat x31 shopt hostcomplete $ ./bash ./x31 hostcomplete on $ ./bash -c 'shopt hostcomplete' hostcomplete on $ ./bash --version GNU bash, version 4.3.30(881)-maint (i386-apple-darwin12.2.0) Copyright (C) 2014 Free Software Foundation, Inc.
