You manage SELinux file contexts by showing the current context and then applying the policy’s default to the file. First, display the SELinux context for the file with ls -Z filename. This prints the security context currently assigned to that specific file, giving you a snapshot to verify. If you find it isn’t the correct default, restore it using restorecon -v filename. The restorecon command consults the SELinux policy and reapplies the default context for that path, and the -v option makes it show exactly what changes were made. This combination ensures you both verify and revert to the sanctioned context. Other approaches don’t fit as well: listing without a filename shows contexts for multiple items rather than a single file; changing the context with chcon sets a new, user-specified context rather than the policy’s default; getenforce only reports whether SELinux is enforcing; and using restorecon without -v would still restore correctly but wouldn’t provide visibility into the changes.
