I have an .inputrc file set up on a system that doesn't seem to be respecting it. If I bind the file (as per this post) or try to load it with C-x C-r, nothing happens - I still do not get any of the readline functions I'm looking for, especially history-search-backward.
Is it possible I'm using a bash shell without readline enabled? If so, how do I determine that definitively? If not, is there something else I need to do to enable readline? The system in question is SUSE Linux version 3.16.7-21-desktop
EDIT with additional information:
$ echo $SHELL
/bin/bash
$ bash --version

.inputrc (including my comments). I'm using this same .inputrc on many other machines, so I don't expect it is the problem:
# "\e[A" and "\e[B" being whatever your terminal uses for up & down.
"\e[A": history-search-backward
"\e[B": history-search-forward
# Two escapes clear command line.
"\e\e": "\C-a\C-k"
# do history expansion when space entered
# Space: magic-space
#set editing-mode vi
$include /etc/inputrc
