Every file here is a shell script that the README invites people to run as root, and nothing has been linting them: .github/workflows was deleted in 5eadf64 and never replaced. The bugs found in this week's audit -- values interpolated into a command string, an unguarded find -delete, exit statuses read from $? after the fact -- are largely the class a linter catches for free. Starts at severity: error deliberately. The existing scripts have never been through a lint pass, so failing on warnings from day one would block every PR on pre-existing findings rather than on new ones. The intent is to tighten to warning, then to nothing, as the backlog is cleared.
Linux System Administration Scripts
Automate routine tasks: This project provides a collection of Bash scripts to automate common Linux system administration duties. Automating daily sysadmin tasks improves efficiency and consistency by reducing manual repetition and the risk of human error. Each script is designed to be distribution-agnostic, using only standard base utilities (e.g. rsync, tar, awk, grep, netstat/ss, systemctl) available on most Linux systems. All scripts are released under the GNU GPL v3.0 license and include usage information in their headers.
