[daxgames]

@xy2z Works for me.

[xy2z]

@daxgames did you restart cmder?

[daxgames]

In the screenshot above , no. I have since restarted though and it works fine. All aliases are there..

[daxgames]

or maybe not.

Looks like it removes all 2 character aliases from the file.

Oh, probably something is using the alias name in a regular expression to remove it, but neglected to escape the alias name. And then the . characters are interpreted as "match any character" by the regular expression.

For example, probably alias .d=abc will remove all two character aliases where the second character is d.

Fixed in #2449

[chrisant996]

Oh, it's using findstr. FWIW then, an even easier and more thorough fix could be to use the /l flag (and the /b flag) to disable regex evaluation, since it's trying to do a literal search.

@chrisant996 My fix works, yours is better and may go in a future change.

Did you see the bug report on 1.3.17 release 1ith Clink 1.1.10 reg clink settings and history? Not really a bug but if you have suggestions on how to best handle from Cmder side it would be helpful.
