Linux Networking Shell Basics

UNIX/Linux command collection for networking lookups, system inspection, and a few Bash utilities.

Repository Areas

Directory	Contents
network/	Commands around interfaces, routing, DNS, ARP, traceroute, and services
system/	System information, users, processes, packages, paths, and permissions
scripting/	Bash scripts plus an interactive menu for browsing/running items

Some commands reflect BSD/macOS style output (ifconfig en0, netstat -nr) and may need adjustment on a modern Linux host.

Run

Inspect a command file:

cat network/04
cat system/01

Run the menu:

cd scripting
./03

Run the user listing script:

cd scripting
./01

scripting/02 can delete local users. It is blocked by default and requires an explicit opt-in:

cd scripting
ALLOW_USER_DELETE=1 ./02

Review it before running on any real machine.

Check Syntax

bash -n network/* system/* scripting/*

The GitHub Actions workflow runs Bash syntax validation for all files under network/, system/, and scripting/.
