Occurs in bash 4.4 and later. Rudimentary test results: 4.2.53(1)-release : pass 4.3.0(1)-release : pass 4.3.30(1)-release : pass 4.3.48(1)-release : pass 4.4.0(1)-release : fail 4.4.12(1)-release : fail 4.4.18(1)-release : fail 5.0.0(1)-release : fail 5.0.9(1)-release : fail - Alex Kerzner Repeat-By: ~~~ # Long way, but potentially easier to implement a test case for bash +o history # attempt to start a new shell with history disabled set -o | grep history # See that history is still on ~~~ ~~~ # Short way, a sweet and simple method bash +o history -i -c 'set -o | grep history' ~~~ In both cases: Expected: 'history off' printed; command not sent to history file (if shell is interactive, etc.) Actual: 'history on' printed; command sent to history file (if shell is interactive, etc.)
