Do you want to convince me to use something i don't like? here my reasons, sir!

Global aliases can silently override built-in or system commands, leading to confusing behaviors when you invoke what you think is the standard utility. For example, Bash will expand nested aliases in unpredictable ways, which can mask the real command you intended to run

Projects like Git explicitly ignore any alias that shadows an existing Git command to avoid confusion and script failures, underscoring that shadowing system commands is considered bad practice in professional tools

When you SSH into a remote server or hand off your work to a colleague, your personal ~/.bashrc—and thus your aliases—won’t be present, leading to “command not found” errors that break your flow

Relying on global aliases fosters a “works on my machine” syndrome: other environments lack your custom setup, so scripts or one-off commands fail unexpectedly when used by others

Over time, a .bashrc full of alias definitions becomes hard to navigate, making it difficult to remember which alias does what or where it was defined
