I've got a ton, most are already listed or along the same vein.
The two suggestions I have are not actual aliases but worth remembering:
- Ctrl + Alt + E - turn your alias into its original command
- \ - Place before your alias to run the original command's meaning. Useful if you overwrite a default command (overwriting default commands is not recommended though... often the alias will ignore any options passed through and so let's say you overwrite
rmwith another app that deletes files, then you forget that, and then try to delete some files usingrm-i to get a prompt for each removed file. Often the alias will just operate as normal w/o a prompt saying that it ignored-icompletely)
