Usage Notes

Run the scripts as the root user; Ubuntu and Debian require enabling root login first.

Install lrzsz to transfer the script files, then execute with bash reset_v10.sh. The interactive menu offers 26 options, including NIC renaming, network configuration, hostname setting, repository configuration, firewall and SELinux toggling, swap disabling, timezone setting, kernel and resource tuning, SSH hardening, PS1 customization, default editor selection, history format, and more.

When changing CentOS Stream 9/10 mirrors, ensure update_mirror.pl is present in the same directory as the reset script.

Follow the on‑screen prompts to select actions; choose option 26 to exit the script.
