C development often involves **three API layers**:
• C standard library
• OS system calls
• POSIX APIs for portability
The standard library stays intentionally small — which is why POSIX became so important for Unix systems.

It's so great to have a standard like POSIX...
locations of explicit_bzero by platform:
linux: string.h if __USE_MISC is defined
freebsd: strings.hif __BSD_VISIBLE is defined
openbsd: string.h if __BSD_VISIBLE is defined
haiku: bsd/string.h
alpine: string.h if _GNU_SOURCE or _BSD_SOURCE is […]
that has pizza-box systems that can be arranged into a tower configuration as needed or desired.
Also said system line's OS is intended to break the current monopoly that #MacOS has on the desktop #POSIX market.

TIL: Starting with Fish Shell 4.0, it supports the POSIX shell `export` command for setting environment variables. This is implemented as a backward-compatible shim for the Fish `set` command, which may be superior but non-standard.

tfw you realize each '=' in the value of an environment variable creates an extra variable

To those who use Linux or other POSIX-compatible system: What was your first OS?
Mine was Ubuntu 8.04 Hardy Heron. It was quiet a lot of fun those days, and it was kinda cool to get the CD from local Ubuntu community.
How about you?

Non-POSIX shells like fish can cause script compatibility headaches. A common strategy: use bash for scripting & system functions, while enjoying fish's interactive features for daily terminal work. Balance power with interoperability! #POSIX 5/5
