semanage fcontext

Manage persistent SELinux security context rules on files/directories. See also: semanage, restorecon. More information: https://manned.org/semanage-fcontext.

• List all file labelling rules:

sudo semanage fcontext --list

• List all user-defined file labelling rules without headings:

sudo semanage fcontext --list --locallist --noheading

• Add a user-defined rule that labels any path which matches a PCRE regex:

sudo semanage fcontext --add --type {{samba_share_t}} {{'/mnt/share(/.*)?'}}

• Delete a user-defined rule using its PCRE regex:

sudo semanage fcontext --delete {{'/mnt/share(/.*)?'}}

• Relabel a directory recursively by applying the new rules:

restorecon -R -v {{path/to/directory}}
