Prevent accidental history editing in bash
Is it possible to prevent bash from editing the commands that have already been run?
It is possible to to prevent this "feature". I found the solution via this answer over on unix.stackexchange.
To summarize, you need to enable the revert-all-at-newline
readline setting which is off by default. If the setting is on then bash will revert any changes you made to your history when you execute the next command.
To enable this setting in your shell, you should add the following to your ~/.inputrc
file and then restart your shell:
$include /etc/inputrcset revert-all-at-newline on
The first line is needed because I guess that if you supply your own .inputrc
file the default /etc/inputrc
file is not included which is probably not what you want.
