When adding some aliass to .inputrc I noticed my 'a' key wasn't working on my keyboard when using Cygwin Bash. Took out all my alias and my 'a' key started working again. For testing I stripped down my .inputrc to look like this:
alias foo='ls'
set bell-style none
Here is what I noticed
- If I type 'foo' at command prompt I get 'bash: foo: command not found'
- I also can't type 'a' without a beep.
- I also don't get any beeping so 'set bell-style none' was set.
If I take out 'set bell-style none' here is what I noticed:
- My system beeps when I press 'a' but 'a' doesn't show on screen.
- If I type 'foo' at command prompt I get 'bash: foo: command not found'
- My system beeps.
If I take out "alias foo='ls'" here is what I noticed:
- Pressing 'a' works.
- Everything else works as normal.
- If I type in "alias foo='ls'" and type "foo" I get a list of directories.
I went looking for some type of logged error but couldn't find anything.
Thanks, Michael

It might be worth explaining what the
aliasline was actually causing Readline to do, and hence the beeps. – JdeBP – 2014-03-08T13:53:32.297I really have no idea, as
alias foo='ls'is completely incorrect syntax. I presume (unless disabled by a previous configuration setting) that readline would ring the bell in an attempt to warn the user when it encounters (attempts to execute) an incorrect key binding. – user19087 – 2014-03-08T20:46:47.373It's incorrect syntax that gets treated as a binding for the character that is the first letter of the word "alias", because Readline's configuration file parser has some poor error checking.
