semanage fcontext

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

  • List all file labelling rules:

sudo semanage fcontext {{[-l|--list]}}

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

sudo semanage fcontext {{[-l|--list]}} {{[-C|--locallist]}} {{[-n|--noheading]}}

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

sudo semanage fcontext {{[-a|--add]}} {{[-t|--type]}} {{samba_share_t}} {{'/mnt/share(/.*)?'}}

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

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

  • Relabel a directory recursively by applying the new rules:

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