Welcome to the **DarkWorld Shells (DWShells)** FAQ.  
DWShells are secure, Linux-based shell accounts provided by the **DarkWorld Network** for IRC community members.  
They allow users to:
* Run **IRC bots**, **ZNC bouncers**, and **automation scripts**  
* Learn **Linux commands**, **network management**, and **system administration**  
* Participate in a shared, community-driven environment

All DWShells are hosted on **Debian Linux** systems with IPv6 support, isolated user environments, and strict uptime and security standards.  
Access is free for verified DarkWorld users and subject to the [[DWShells/Rules|DWShells Usage Rules]].

== 🐧 Linux vs 🐚 Unix/OpenBSD Shells ==

Many users ask whether a **Linux shell (Debian)** is the same as a **Unix or OpenBSD shell**.  
Both systems feel similar at the command line and support IRC bots, ZNC, and scripts — but they differ in design philosophy, package tools, and security focus.

* **Linux (Debian):** Flexible, user-friendly, widely supported  
* **OpenBSD (Unix):** Minimalist, extremely secure, true Unix lineage  
* For IRC use, both work perfectly — it’s mostly about preference and purpose.

Many IRC users ask if a '''Linux shell''' (like the Debian shells offered on DarkWorld) is the same as a '''Unix''' or '''OpenBSD''' shell.  
The short answer:  
> 💬 Both feel similar at the command line, but differ in how the system is built and managed underneath.

Both allow you to host IRC bots, ZNC, and run shell scripts effectively.

----

== 🧩 Overview ==
DarkWorld provides Debian (Linux) shell accounts. Other IRC networks may offer OpenBSD or other Unix-based shells.  
For users, both let you run commands, scripts, bots, and IRC tools — the experience is 90% the same. The difference is mainly in system philosophy, package tools, and security approach.

== Frequently Asked Questions ==

=== 1. Is a Linux shell “different” from a Unix (OpenBSD) shell? ===
Not much for normal users — both are Unix-style shells where you can use commands, scripts, and bots.  
The difference is that Linux is a '''Unix clone''' (recreated from scratch), while OpenBSD is a '''direct Unix descendant''' (from the BSD family).

=== 2. Will my commands and scripts work the same on both? ===
* Most core commands (`ls`, `cd`, `grep`, `awk`, `sed`, `find`, etc.) behave the same.  
* Bash scripts written for Linux usually work on OpenBSD if you install `bash`.  
* The default shell on OpenBSD is `ksh`, not `bash`.  
* A few GNU-specific options (like `ls --color` or `grep -P`) may not work the same.

=== 3. What about installing packages and updates? ===
* **Debian/Linux:** Use `apt`, `apt-get`, `dpkg`.  
* **OpenBSD:** Use `pkg_add`, `pkg_info`, or compile from Ports.  
Linux offers huge repositories; OpenBSD offers smaller, carefully audited ones.  
Both keep software updated and secure.

=== 4. Which is more secure or stable? ===
* **OpenBSD:** Known for its extreme security focus and clean code.  
* **Debian:** Very secure too, but optimized for usability and wide compatibility.  
In practice, both are safe for IRC shells when properly configured.

=== 5. Does performance differ? ===
Both are fast and lightweight for normal shell usage.  
OpenBSD prioritizes simplicity and correctness; Debian may handle more processes and newer packages faster.

=== 6. Can I host ZNC, bots, and IRC tools on both? ===
Yes.  
ZNC, Eggdrop, BNCs, and most bots run fine on either.  
Linux tends to have more prebuilt binaries, while OpenBSD may require manual compilation.

=== 7. Why would a network choose one over the other? ===
* '''Linux (Debian)'''
  * Easier to maintain, more packages, larger support community  
  * Flexible and widely documented  
  * Perfect for beginners or multi-purpose hosting  
* '''OpenBSD'''
  * Exceptional security and reliability  
  * Minimalistic system with clean configuration  
  * Great for users who prefer a pure Unix environment

=== 8. Are there missing tools or features on one system? ===
* On OpenBSD, some GNU extensions may be missing (e.g. colorized ls, GNU sed).  
* Debian includes many GNU tools by default, which can be more feature-rich.  
* Both can install missing utilities with their package manager.

=== 9. How can I make my scripts portable across both systems? ===
* Use '''POSIX-compatible shell syntax''' instead of Bash-only features.  
* Test scripts with `/bin/sh` instead of `/bin/bash`.  
* Avoid GNU-only options unless necessary.  
* Example: use `printf` instead of `echo -e`.

Example portable script:
<syntaxhighlight lang="bash">
#!/bin/sh
echo "Hello from $USER on $(uname -s)"
</syntaxhighlight>

=== 10. Where can I read the full technical comparison? ===
See [[DWShells/Linux_vs_Unix_Shells|Linux vs Unix Shells]] for a complete table comparing design, performance, and security differences.

== ⚙️ User Tips ==
* Check `man` pages — options can differ slightly between systems.  
* On OpenBSD, remember to `pkg_add bash` if you want the same shell experience as Linux.  
* Use `uname -a` to see which system you are on.  
* Ask on IRC if unsure — DarkWorld ops and community members can help with shell issues.
