Machine Type: x86_64-unknown-linux-gnu
Bash Version: 4.2
Patch Level: 10
Release Status: release
Description:
The "history -s" usually removes the last history item which
is usually the "history -s" command itself, but PROMPT_COMMAND
disables history and causes an unrelated command to be deleted.
Repeat-By:
$ history -s '# line 1' ; history -s '# line 2' ; history 2
X1 # line 1
X2 # line 2
$ PROMPT_COMMAND="history -s '# line 3' ; history -s '# line 4'"
$ history 5
X1 # old command
X2 # line 1
X3 # line 2
X4 # line 3
X5 # line 4
Expect:
X1 # line 1
X2 # line 2
X3 PROMPT_COMMAND="history -s '# line 3' ; history -s '# line 4'"
X4 # line 3
X5 # line 4
No new commands will enter history as they are replaced with $'# line
3\n# line 4'
Fix:
Either add a switch to disable the deletion, or stop the
auto-delete when history is disabeled in:
parse.y 2466: parse_and_execute (savestring (command), vname,
SEVAL_NONINT|SEVAL_NOHIST);
