The workflow went in at severity: error on the assumption that a never-linted repository would have a backlog worth grandfathering. It did not -- error found nothing, and warning found exactly two things, so the cautious setting was protecting against a problem that was not there. zimbra_backup.sh: SC2024, sudo does not affect redirects. The `> "$BACKUP_FILE"` runs as root rather than as the sudo'd zimbra user, so backups landed root-owned inside a directory the script deliberately chowns to zimbra:zimbra. Kept the redirect -- root can always write there, and piping into `tee` would put tee's status in $? and hide a zmmailbox failure -- and handed ownership over explicitly afterwards. The suppression is narrow and states why. disk_cleanup.sh: SC2034, total_freed was assigned and never read. CI now holds at warning with a clean tree, so anything that trips it is new rather than inherited.
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.
Included Scripts
