what is the difference of "apt-get install -qy" and "apt install -y"

 The difference between the two commands:

1. apt-get install -qy <package>

   • Uses apt-get, which is the older command-line tool for package management.
   • The -q (quiet) flag reduces the output verbosity.
   • The -y flag automatically answers "yes" to prompts.

2. apt install -y <package>

• Uses apt, which is a newer and more user-friendly wrapper around apt-get.
• The -y flag automatically answers "yes" to prompts.
• apt provides more user-friendly output and progress bars compared to apt-get.

Key Differences:

• apt-get vs. apt: apt-get is a lower-level tool, while apt is a more modern, interactive tool.
• -q flag in apt-get: This reduces output, whereas apt does not require it since apt already optimizes verbosity.

When to Use Which?

• Use apt-get install -qy in scripts where minimal output is preferred.
• Use apt install -y for interactive use, as it provides a better user experience.

For most modern usage, apt install -y is recommended unless you specifically need apt-get for legacy or scripting purposes.
