This is really not what should be happening. |
Some users elect to copy /etc/bash/bashrc to ~/.bashrc, resulting in double-sourcing. Perhaps you are among them? There is now a check to warn users of this particular misconfiguration. |

| I have submitted a patch which, if accepted, will address the matter by refraining from defining an alias in the case that an alias or function already exists by the specified name. |

Indeed. Here's POSIX on the matter. |
Well, that's the brand new POSIX standard. Not sure whether it is already officially released or still a topic under discussion, but I am quite sure that it was not released before 2024. |

The alias utility was introduced by the publication of X/Open Common Applications Environment (CAE) Portability Guide Issue 4, also known as XPG4. That was in 1992. It was subsumed by the Single UNIX Specification in 1994. |

Afaik SUS is a superset of POSIX. Right?
Although 1994 is already 30 years ago. So I would guess the standard (alias) would have been included in POSIX by now then.

Allow me to settle this once and for all.
- alias was introduced in an official capacity by XPG4
- XPG4 was assimilated by SUSv1
- alias was therefore present in SUSv1
- alias was therefore present in SUSv2
- alias was therefore present in SUSv3, which is essentially the same as POSIX-1.2001
- POSIX-1.2001 consolidated the POSIX.1, POSIX.2, and SUS standards through the efforts of the Austin Group

So based on these, alias was standardized into POSIX in 2001 (Or in beginning of 2002).

Yes. At that point, it became an element of Shell and Utilities, Issue 6 (XCU). There it has remained through all of the subsequent issues and so-called technical corrigenda. |
