how can I override alias set in .bash_aliases

Question

I like to use bash aliases to customize bash commands. Is there a way to override the bash alias settings, or should I rename the aliases to something different than the original command.

eg: my .bash_aliases includes

alias ls='ls -ltr' 

If I want to only retrieve the file name, do I need to rename the alias to something other than 'ls'? Or is there another way?

Answer 1

Add a \ (backslash) before the command to disable the alias, like this:

\ls

This will invoke the original (un-aliased) ls.

Example:

$ ls #will invoke the alias total 0 -rw-rw-r--    1 dogbane foo          0 Nov  3 16:04 c -rw-rw-r--    1 dogbane foo          0 Nov  3 16:04 b -rw-rw-r--    1 dogbane foo          0 Nov  3 16:04 a  $ \ls #will disable the alias a  b  c
